MAX696CWE+

The MAX696CWE+ is a microprocessor supervisory circuit in 16 pin WSOIC package. This supervisory circuit reduce the complexity and number of components required for power supply monitoring and battery control functions in microprocessor (μP) systems. It includes μP reset, backup battery switchover, watchdog timer, CMOS RAM write protection and power failure warning. MAX696 device perform functions such as a reset pulse if the optional watchdog timer has not been toggled within a specified time, individual outputs for low line and watchdog fault conditions. The reset time may be left at its default value of 50ms or may be varied with an external capacitor or clock pulses. A separate 1.3V threshold detector for power fail warning, low battery detection or to monitor a power supply other than VCC. The device significantly improves system reliability and accuracy compared to that obtained with separate ICs or discrete components.
