M62021L System Reset-IC

The M62021 is a system IC that controls the memory backup function of microcomputer (internal RAM). The IC outputs reset signals (RES/RES) to a microcomputer at power-down and power failure. It also shifts the power supply to RAM from main to backup, outputs a signal (CS) that invokes standby mode, .

M62021L Features

* Built-in switch for selection between main power supply and backup power supply to RAM.

* Small difference between input and output voltage (IOUT = 80 mA, VIN = 5 V) 0.2 V Typ

* Detection voltage (power supply monitor voltage) 4.40 V ± 0.2 V

* Chip select signal out
