Using STMicroelectronics Voltage Detectors

1 Introduction

Voltage detectors are designed to monitor the system supply voltage and assert the output
signal, OUT, every time it goes below a defined voltage threshold.
The major advantages of these circuits are low current consumption and a precise
temperature-compensated voltage reference, VREF (see Figure 1). STMicroelectronics
voltage detectors are also laser programmed to the desired voltage threshold over the range
of 1.6V to 6.0V in 100mV steps and
