STM1061 Low Power Voltage Detector

STM1061 Bluetooth Headset Application exampleThe STM1061 low power Voltage Detector provides monitoring of battery, power-supply, and regulated system voltages. A precision voltage reference and comparator monitors the Vcc input and compares it with a specified voltage threshold condition with 2% threshold accuracy. When Vcc falls below a specified threshold, the output (/OUT) is forced low and remains asserted as long as the Vcc input remains below Vth– plus hysteresis (Vhyst).
Available in factory-trimmed voltage thresholds in 0.1V increments
