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.
