A3250 and A3251 are field-programmable, chopper-stabilized, unipolar Hall-effect switches designed for use in high-temperature applications. These devices use a chopper-stabilization technique to eliminate offset inherent in single-element devices. The A3250 and A3251 are externally programmable devices. The devices have a wide range of programmability of the magnetic operate point (BOP) while the hysteresis remains fixed. This advanced feature allows for optimization of the sensor switchpoint and can drastically reduce the effects of variations found in a production environment, such as magnet and device placement tolerances. These devices provide on-chip transient protection. A Zener clamp on the power supply protects against overvoltage conditions on the supply line. These devices also include short-circuit protection on the output.

The A1180, A1181, A1182, and A1183 devices are sensitive, two-wire, unipolar, Hall effect switches. They feature on-chip protection, supply transient protection, reverse-battery protection, an on-board voltage regulator, and operate in the voltage range of 3.5V to 24V. They utilize chopper stabilization, exhibit low switchpoint drift over the operating temperature range, and have low stress sensitivity. They can be field-programmed to optimize switchpoints.

UDN2580 series is a versatile integrated circuit that can work with many combinations of logic and load voltage levels, meeting interface requirements beyond the capabilities of standard logic buffers. UDN2580A and A2580SLW source drivers can drive incandescent, LED, or vacuum fluorescent displays. Internal transient-suppression diodes permit the drivers to be used with inductive loads such as relays, solenoids, dc and stepping motors, and mag- netic print hammers. The Types UDN2580A and A2580SLW are high-current source drivers used to switch the ground ends of loads that are directly connected to a -50 V supply. Typical loads are telephone relays, PIN diodes, and LEDs. The UDN2585A and A2585SLW are drivers designed for applications requiring low output saturation voltages. Typical loads are low-voltage LEDs and incandescent displays. The eight non-Darlington, 25 V outputs will simultaneously sustain continuous load currents of -120 mA at ambient temperatures to +70°C. The UDN2588A and A2588SLW have separate logic and driver supply lines. Their eight drivers can serve as an interface between positive logic (TTL, CMOS, PMOS) or negative logic (NMOS) and either negative or split- load supplies to -80 V. These drivers are packaged in plastic DlPs (suffix A) or surface-mount- able wide-body SOlCs (suffix LW), and are rated for operation over the temperature range of -20°C to +85°C.

The UGN/UGS3059KA and UGN/UGS3060KA ac-coupled Hall-effect gear-tooth sensors are monolithic integrated circuits that switch in response to changing differential magnetic fields created by moving ferrous targets. These devices are ideal for use in non-zero-speed, gear-tooth-based speed, position, and timing applications such as in anti-lock braking systems, transmissions, and crankshafts.
