Maxim MAX703CSA

备用电池电路4.65V1

Overview

The  MAX703/MAX704  microprocessor  (μP)  supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions  in  μP  systems.  These  devices  significantly improve system reliability and accuracy compared to that obtained with separate ICs or discrete components.

● Battery-Backup Power Switching● Precision Supply-Voltage Monitor • 4.65V (MAX703) • 4.40V (MAX704)● 200ms Reset Pulse Width● Debounced TTL/CMOS-Compatible Manual Reset Input● 200μA Quiescent Current● 50nA Quiescent Current in Battery-Backup Mode● Voltage Monitor for Power-Fail or Low-Battery Warning● 8-Pin DIP and SO Packages● Guaranteed RESET Assertion to VCC = 1V
