FEATURES Nanopower Voltage Detector in Single 4 mm 2 Package Ultra Low Total Supply Current: 1µA (max) Supply Voltage Operation: 0.65V to 2.5V Preset 0.78V UVLO Trip Threshold Internal ±10mV Hysteresis Resettable Latched Comparator Complimentary and Open-drain Comparator Outputs Separate Comparator Output Supply Pin APPLICATIONS Power-Fail Indicator Low-Battery Detection Battery-Backup Detection CPU, Microprocessor, and Logic Reset Controller Battery-powered Systems DESCRIPTION The TS12001 voltage detector combines a 0.58V reference and a comparator with resettable comparator latch in a single package. The TS12001 operates from a single 0.65V to 2.5V power supply and consumes less than 1µA total supply current. Optimized for ultra-long life operation, the TS12001 expands Touchstone’s growing “NanoWatt Analog™” high-performance analog integrated circuits portfolio. The voltage detector exhibits a preset UVLO threshold voltage of 0.78V (typ) or can be set to other threshold voltages with two external resistors. The comparator exhibits ±10mV of internal hysteresis for clean, chatter-free output switching. The TS12001 also offers both push-pull and open-drain outputs. When compared against similar products, the TS12001 offers a factor-of-2 lower power consumption and at least a 33% reduction in pcb area. The TS12001 is fully specified over the -40°C to +85°C temperature range and is available in a low- profile, 10-pin 2x2mm TDFN package with an exposed back-side paddle. A 0.65V/1µA Nanopower Voltage Detector with Dual Outputs TYPICAL APPLICATION CIRCUIT The Touchstone Semiconductor logo and “NanoWatt Analog” are registered trademarks of Touchstone Semiconductor, Incorporated. A Nanopower 1.8V Core System Voltage Detector |
