• LINEAR LT 1331 3V RS562 or 5V/3V RS232 Transceiver with One Receiver Active in Shutdown handbook

  This datasheet provides the features and characteristics of the LT1331. The LT1331 is a 3-driver, 5-receiver RS232 transceiver designed for 3V and mixed 3V/5V systems. Receivers operate from 3V logic supply VL, while the onboard charge pump and drivers operate from 5V or 3V supply VCC. The transceiver has two shutdown modes. One mode disables the drivers and the charge pump, the other shuts down all circuitry except for one low power receiver which can be used for ring detection. The VCC supply may be shut down while in ring detection mode. While shut down, the drivers and receivers assume high impedance output states. When VCC = 5V, the LT1331 is fully compliant with all EIA-RS232 specifications. If VCC = 3V, output drive levels are compatible with all known interface circuits. Special bipolar construction techniques protect the drivers and receivers beyond the fault conditions stipulated for RS232. The RS232 I/O pins are resilient to multiple ±10kV ESD strikes. An advanced driver output stage operates up to 120kbaud while driving heavy capacitive loads.

• LINEAR Dual Monolithic Ideal Diode Manages Multiple Power Inputs Design Note 356 handbook

  This document introduces the LTC4413 dual monolithic ideal diode, which helps to reduce the size and improve the performance and reliability of handheld battery-operated devices. The device can automatically select and isolate up to three power sources, such as a wall adapter, an auxiliary supply and a battery. It provides a low loss automatic PowerPath TM management solution for demanding applications that may require short-circuit protection, thermal management and system-level power management and control. The LTC4413 contains two isolated low voltage (2.5V to 5.5V) monolithic ideal diodes. Each ideal diode channel provides a low forward voltage drop (typically as low as 40mV when conducting low current) and a low RDS(ON) (below 100mΩ) when conducting high current—features that are important to extend battery life and reduce heat in portable applications. Furthermore, each channel is capable of providing up to 2.6A of continuous current from a small 3mm × 3mm, 10-pin DFN package. Current-limit and thermal shutdown features further enhance system reliability.
