0.58V reference, 0.65µW voltage detector with dual o/ps from Touchstone

Touchstone Semiconductor has announced the new TS12001 voltage detector that combines a 0.58V reference and a resettable latched comparator in a single package.

The TS12001 can be used in fixed-platform and battery-powered systems. The main applications include power-fail indicators, low-battery and battery-backup detection, and CPU/microprocessor/logic reset controllers.

The device works from a single 0.65V to 2.5V power supply and consumes less than 1µA total supply current. This detector generates a reset signal whenever the monitored voltage drops below an internally preset 0.78V threshold or below an external, resistor-programmable reset threshold voltage.

The internal comparator of the device shows ±10mV of hysteresis for clean, chatter-free output switching. The TS12001 also provides both push-pull and open-drain outputs. Its push-pull output can source or sink current and the open-drain output can be used in wired-OR or mixed system voltage applications.

The device operates over the -40 DegC to +85 DegC temperature range and is available in a low-profile, 10-lead 2 x 2 mm TDFN package with an exposed back-side paddle.

The device is in stock and ready to ship from Touchstone’s worldwide distributor, Future Electronics at a price starting $0.32 each in 1,000 piece quantities.
