This pin is the current sense recopy of the external SMART MOSFET.
This input wakes the device. It also controls the Outputs 1 and 2 in case of Fail
mode activation. This pin has a passive internal pull-down.
This input wakes the device. It is also used to initialize the device configuration
and fault registers through SPI. This digital pin has a passive internal pull-down.
This input wakes the device. This pin has a passive internal pull-down.
This pin state depends on RST logic level.
As long as RST input pin is set to logic [0], this pin is pulled up in order to report
wake event. Otherwise, the PWM frequency and timing are generated from this
digital clock input by the PWM module.
This pin has a passive internal pull-down.
The Fail mode can be activated by this digital input. This pin has a passive
internal pull-down.
This input wakes the device. This pin has a passive internal pull-down.
When this digital signal is high, SPI signals are ignored. Asserting this pin low
starts a SPI transaction. The transaction is signaled as completed when this
signal returns high. This pin has a passive internal pull-up resistance.
This digital input pin is connected to the master microcontroller providing the
required bit shift clock for SPI communication. This pin has a passive internal
pull-down resistance.
