Pin descriptions
Power supply (V
This pin is used to provide the power to the Smart Reset™ device and to monitor the power
supply. A 0.1 µF decoupling ceramic capacitor is recommended to be connected between

This is the supply ground for the device.
Smart Reset™ push-button inputs (SR0, SR1)
Both SR0 and SR1 need to be held active at the same time for at least t
reset output pulse. Include an internal 65 kΩ pull-up resistor to V
