Touchstone Semiconductor Announces Its Newest 0.65µW Voltage Detector with Dual Outputs
The New TS12001 Cuts Power Consumption by 2 and Reduces PCB Area by 33%
MILPITAS, Calif. – June 26, 2012 – Touchstone Semiconductor, a developer of high-performance, low power analog integrated circuit solutions, today announced the new TS12001 voltage detector, which combines a 0.58V reference and a resettable latched comparator 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. This 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. The TS12001 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.
The TS12001 is an ideal choice for fixed-platform and battery-powered systems where total PCB area and power consumption matter. Target applications for the TS12001 include power-fail indicators, low-battery and battery- backup detection and CPU/ microprocessor/logic reset controllers.
