P POWER SUPPLY SUPERVISOR WITH BATTERY BACKUP SWITCH

IMP690A Features

* of these four functions are: a) 1.6 second watchdog timer to keep microprocessor responsive b) c) 4.40V or 4.65V VCC threshold for microprocessor reset at power-up and power-down SPDT (single-pole, double-throw) PMOS switch connects backup power to RAM if VCC fails Key Features x Design improvement

IMP690A General Description

Pin Number IMP690A/IMP692A IMP802L/IMP802M 1 IMP805L 1 Name VOUT Function Voltage supply for RAM. When VCC is above the reset threshold, VOUT connects to VCC through a P-channel MOS device. If VCC falls below the reset threshold, this output will be connected to the backup supply at VBATT (or VCC.
