MAX6364PUT44中文资料美信数据手册PDF规格书

General Description

The MAX6361–MAX6364 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in microprocessor (µP) systems. The circuits significantly improve system reliability and accuracy compared to that obtainable with separate ICs or discrete components.

Their functions include µP reset, backup battery switchover, and power failure warning.
