TS3121IYLT

TS3121IYLT is a rail-to-rail, open-drain comparator with embedded fail-safe input/output. The device can operate with input/output pins biased while the supply pin is shut down to VCC = 0V for energy saving applications. A guaranteed start-up time ensures a stable output condition after activating the supply rail. It can be used in applications where space on the board is limited. It can thus reduce the overall cost of the PCB. Typical applications include industrial, automotive, power tools, overcurrent protection, controllers, sensors.
