The DS1236 power supply controllerThe working voltage is 5.0V; the working temperature range is -40~85℃; it can halt or restart the malfunctioning microprocessor; it can be used in external overload key monitoring; when the power supply fault is approaching, it will send the forecast to the processor; it converts static RAM into non-easy-lost storage; when the power supply voltage fault is too large, it will fulfill writing protection unconditionally; the cell current is lower than 100nA; the monitor precision is 10%Vcc, the monitor precision of DS1236-5 is 5%/Vcc. The main pins are as follows:VBAT: the +3 battery voltage input; VCC0: the switch SRAM power supply output.
