Overview
The TLV3701CDBVR, part of the TLV370x family, is a nanopower push-pull output comparator manufactured by Texas Instruments. This device is notable for its extremely low supply current of 560 nA per channel, making it ideal for battery-powered and wireless handset applications. The TLV3701CDBVR operates over a wide supply voltage range from 2.7 V to 16 V and features an input common-mode range that exceeds the rails, from –0.1 V to VCC + 5 V. It is designed to provide robust performance in harsh environments, including reverse battery protection up to 18 V and the ability to handle inputs 5 V above the positive supply rail without damage.
