Pin descriptions
Power supply (V
This pin is used to provide power to the Smart Reset device. A 0.1 µF ceramic decoupling
capacitor is recommended to be connected between the V
STM6519 device as possible.
Ground (V
This is the ground pin for the device.
Smart Reset input (SR)
Push-button Smart Reset input, active-low with optional pull-up resistor. SR input needs to
be asserted for at least t
By connecting a voltage higher than V
(see
Reset output (RST)
RST is active-low or active-high, open drain or push-pull reset output with optional internal
pull-up resistor.
Output reset pulse width is optional as follows:
