FETIN
Input External FET Input _{This pin is the current sense recopy of the external SMART MOSFET.}
2
IGN
Input
Ignition Input _{This input wakes the device. It also controls the Outputs 1 and 2 in case of Fail}
(Active High) _{mode activation. This pin has a passive internal pull-down.}
3
RST
Input
Reset
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.
4
FLASHER
Input
Flasher Input
(Active High)
This input wakes the device. This pin has a passive internal pull-down.
5
CLOCK Input/Output
Clock Input
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.
6
LIMP
Input
Limp Home Input _{The Fail mode can be activated by this digital input. This pin has a passive}
(Active High) _{internal pull-down.}
7
FOG
Input
FOG Input (Active This input wakes the device. This pin has a passive internal pull-down.
high)
8
CS
Input
Chip Select
When this digital signal is high, SPI signals are ignored. Asserting this pin low
(Active 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.
9
SCLK
Input
SPI Clock Input 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.
