Touchstone Semiconductor announced TS12001 voltage detector combining a 0.58V reference and a resettable latched comparator in a single package.
The chip operates from a single 0.65V to 2.5V power supply and consumes less than 1µA total supply current. The device produces 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 TS12001’s internal comparator exhibits ±10mV of hysteresis for clean, chatter-free output switching. It also offers 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.
Target applications for the TS12001 include power-fail indicators, low-battery and battery-backup detection, and CPU/ microprocessor/logic reset controllers.
Pricing starts at $0.32 each in 1,000 piece quantities.
