The document provides an overview of STMicroelectronics voltage detectors, which monitor system supply voltage and assert an output signal when it drops below a defined threshold. Key features include low current consumption, precise temperature-compensated references, and laser-programmed thresholds ranging from 1.6V to 6.0V in 100mV steps.
Typical applications include battery monitoring, power-supply monitoring, portable medical devices, and power fail detection.
The detectors are laser programmed to operate over a range of 1.6V to 6.0V in 100mV steps.
A 10kΩ pull-up resistor is sufficient in most applications.
