DESCRIPTION
The TS12001 voltage detector combines a 0.6V reference and a 35µs 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 0.8V (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-TBD lower power consumption and at least a 55% 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.
