Pin Function
Delay Set Input: Connect external capacitor to GND to set the
Common Ground.
Open-Drain Output: Capable of sinking 150mA.
Power-On Reset Output: Open-drain output. Active low indicates
The exposed pad must be soldered to a large PCB and
Active high signal drives open-drain N-MOSFET.
Note that this pin is high impedance. There should be a pull low
100kΩ resistor connected to GND when the control signal is
floating.
