FUNCTION
Ground
Active-Low Open-Drain Output. Connect to an external pullup resistor. Can be pulled up to a voltage higher
than V CC , but less than 6V.
Manual Reset Input. A logic-low on MR asserts reset. Reset remains asserted as long as MR is low, and for
the reset timeout period (t RP ) after the reset conditions are terminated. Connect to VCC if not used.
Supply Voltage and Reset Threshold Monitor Input
