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 the 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.
