TIOS101 Digital Sensor Output Drivers

TIOS101 Digital Sensor Output Drivers

Texas Instruments' TIOS101 devices are configurable as high-side, low-side, or push-pull drivers. These devices are capable of withstanding up to 1.2 kV (500 Ω) of IEC 61000-4-5 surge and feature integrated reverse polarity protection.

A simple pin-programmable interface allows easy interfacing to the controller circuits. The output current limit can be configured using an external resistor. Fault reporting and internal protection functions are provided for undervoltage, over circuit current and overtemperature.
