微处理器电压监视器与 Microprocessor Voltage Monitor with
General Description
The ICL7665 warns microprocessors µPs of overvoltage and undervoltage conditions. It draws a typical operating current of only 3µA. The trip points and hysteresis of the two voltage detectors are individually programmed via external resistors to any voltage greater than 1.3V. The ICL7665 will operate from any supply voltage in the 1.6V to 16V range, while monitoring voltages from 1.3V to several hundred volts. The Maxim ICL7665A is an improved version with a 2%-accurate VSET1 threshold and guaranteed performance over temperature.
