MAXIM INTEGRATED / ANALOG DEVICES MAX690ACSAT Microprocessor Supervisor

The MAX690ACSA+T is an 8-pin NSOI compact microprocessor supervisory circuit designed to simplify power supply monitoring and battery control in microprocessor systems. It enhances system reliability and accuracy compared to using separate ICs or discrete components. The device provides functions such as reset output during power-up, power-down, and brownout conditions; battery backup switching for CMOS RAM and other low-power logic; a 1.25V threshold detector for power fail warnings or low battery detection; and an optional watchdog timer that generates a reset pulse if not toggled within 1.6 seconds. It operates with a supply voltage range of 1V to 5.5V, a temperature range of 0°C to 70°C, features precision supply monitoring at 4.65V, an active low reset, low quiescent current of 50nA in backup mode, and a reset pulse width of 200ms, with reset assertion at VCC = 1V.
