Microprocessor Power Management With Watchdog Timer

The R5101G series are Microprocessor Power Management ICs with high accuracy output voltage and detector threshold and with ultra low supply current by CMOS process. Each of these ICs consists of a voltage Regulator a voltage detector and a watchdog Timer Thus, the R5101G Series have the function of a Power Management for Microprocessor a monitor of the voltage of a power source and a Microprocessor Supervisor The built-in voltage Regulator with an internal driver Transistor CAN supply typically 50mA current to a system when the voltage difference between input and output is 2V. Therefore these ICs are very suitable for various power supply systems for Microprocessors The output voltage is monitored by the voltage detector which is built-in these ICs. The built-in voltage detector has an output delay function and the delay time CAN be set by an external capacitor(CD).
