MAX7306/MAX7307 is an I2C-compatible, serial-interfaced four-level translating I/O device operating from 1.62V to 3.6V. The MAX7307 features a port supply (VLA) that allows level translation on I/O ports to operate from a separate power supply from 1.4V to 5.5V. The MAX7306 features an address select input (AD0) to allow up to four unique slave addresses. MAX7306/MAX7307 ports P2, P3 and P4 can be configured as inputs, push-pull outputs and open-drain outputs. Port P1 can be configured as a general-purpose input, open-drain output or an open-drain INT output. Ports P2 and P3 can be configured as OSCIN and OSCOUT respectively. The MAX7306/MAX7307 include an internal oscillator for PWM, blink and key debounce or to cascade multiple MAX7306/MAX7307s. The external clock can be used to set a specific PWM and blink timing. The RST input asynchronously clears the 2-wire interface and terminates a bus lockup involving the MAX7306/MAX7307. All ports configured as output feature 33-step PWM, allowing any output to be set from fully off, 1/32 to 31/32 duty cycle, to fully on. All output ports also feature LED blink control, allowing blink periods of 1/8 second, 1/4 second, 1/2 second, 1, 2, 4 or 8 seconds. Any port can blink during this period with a 1/16 to 15/16 duty cycle. MAX7306/MAX7307 are specified over the -40°C to +125°C temperature range and are available in 10-pin µDFN (2mm x 2mm) and 10-pin µMAX®.

MAX7304 is a 16-port GPIO and LED driver with I2C interface from MAXIM company, which supports 1.62V to 3.6V power supply and has high level of ESD protection.

The MAX6966/MAX6967 is a serial interface peripheral from Texas Instruments that provides 10 I/O ports that can be configured as either current drivers, logic outputs, or Schmitt logic inputs. It supports PWM dimming and per-LED switching control.

The MAX6946/MAX6947 is an I2C-/SMBusTM-compatible serial-interfaced peripheral that provides microprocessors with 10 I/O ports rated to 7V. Each port can be configured as a 2.5mA to 20mA constant-current LED driver (static or PWM), a 1.25mA to 10mA constant-current LED driver (static or PWM), an open-drain logic output, or an overvoltage-protected Schmitt logic input. Analog and switching LED intensity control includes individual 8-bit PWM control per output, individual 1-bit analog current control (half/full scale) per output, and a global 3-bit DAC current control that applies to all LED outputs. The MAX6946/MAX6947 can stagger the PWM timing of the 10-port outputs in consecutively phased 45° increments. Staggering the outputs spreads the PWM load currents over time in eight steps, helping to even out the power-supply current and reduce the RMS current. For a similar part with an SPITM-/QSPITM-/ or MICROWIRETM- compatible interface, refer to the MAX6966/MAX6967 data sheet.

This document describes a product with open drain PIO pins that can be controlled and their logic level can be determined over 1-Wire bus for closed-loop control. It replaces and is fully compatible with DS2407 but has no user-programmable power-on settings and no Hidden Mode.

The DS28E04-100 is a 4096-bit, 1-Wire® EEPROM chip with seven address inputs. The address inputs are directly mapped into the 1-Wire 64-bit Device ID Number to easily enable the host system to identify the physical location or functional association of the DS28E04-100 in a multidevice 1-Wire network environment. The 4096-bit EEPROM array is configured as 16 pages of 32 bytes with a 32 byte scratchpad to perform write operations. EEPROM memory pages can be individually write protected or put in EPROM- emulation mode, where bits can only be changed from a 1 to a 0 state. In addition to the memory, the DS28E04-100 has two general-purpose I/O ports that can be used for input or to generate level and/or pulse outputs. Activity registers also capture port activity for state change monitoring. The DS28E04- 100 communicates over the single-contact 1-Wire bus. The communication follows the standard Maxim 1-Wire protocol.

The DS2413 is a dual-channel programmable I/O 1-Wire® chip. The PIO outputs are configured as open-drain and provide up to 20mA continuous sink capability and off-state operating voltage up to 28V. Control and sensing of the PIO pins is performed with a dedicated device-level command protocol. To provide a high level of fault tolerance in the end application, the 1-Wire IO and PIO pins are all capable of withstanding continuous application of voltages up to 28V max. Communication and operation of the DS2413 is performed with the single contact Maxim/Dallas 1-Wire serial interface.

The LTC ®2436-1 is a 2-channel differential input micropower 16-bit No Latency ∆Σ TM analog-to-digital converter with an integrated oscillator. It provides 0.5 LSB INL and 800 nV RMS noise independent of VREF. The two differential channels convert alternately with a channel identification included in the conversion result. It uses delta-sigma technology and provides single conversion settling of the digital filter. Through a single pin, the LTC2436-1 can be configured for better than 87dB input differential mode rejection at 50Hz and 60Hz ±2%, or it can be driven by an external oscillator for a user defined rejection frequency. The internal oscillator requires no external frequency setting components. The converter accepts any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The full-scale differential input range is from –0.5 •␣VREF to 0.5 • VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere between GND and VCC. The DC common mode input rejection is better than 140dB. The LTC2436-1 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE TM protocols.

The MAX16060/MAX16061/MAX16062 are 1% accurate, quad-/hex-/octal-voltage µP supervisors in a small thin QFN package. These devices provide supervisory functions for complex multivoltage systems. The MAX16060 monitors four voltages, the MAX16061 monitors six voltages, and the MAX16062 monitors eight voltages. These devices offer independent outputs for each monitored voltage along with a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds (down to 0.4V) or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30µA pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing. An additional feature is a watchdog timer that asserts RESET when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving WDI unconnected. These devices are offered in 16-, 20-, and 24-pin thin QFN packages (4mm x 4mm) and are fully specified from -40°C to +1°C.
