应用功能:过欠压检测微处理器电压监视器 The ICL7665 warns microprocessors (mPs) 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
