MAX690AESA+T

The MAX690AESA+T is a microprocessor supervisory circuit in 8 pin NSOIC package. This device reduces the complexity and number of components required for power supply monitoring and battery control functions in microprocessor (µP) systems. The device significantly improves system reliability and accuracy compared to separate ICs or discrete components. It perform following functions such as reset output during power-up, power-down and brownout conditions, battery backup switching for CMOS RAM, CMOS µP or other low power logic, 1.25V threshold detector for power fail warning or low battery detection or to monitor a power supply other than +5V and reset pulse if the optional watchdog timer has not been toggled within 1.6s. This device is typically used in battery powered computers and controllers, intelligent instruments.
