Pin
Pin Name Pin Function Formal Name
Definition
1
FETIN
Input
External FET Input This pin is the current sense recopy of the external MOSFET.
2
IGN
Input
Ignition Input
This input wakes the device. It also controls outputs 1 and 2 in case of
(Active High)
Fail 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 the SPI. This 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
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 an active
(Active High)
internal pull-down current source.
7
STOP
Input
Stop Light Input
This input wakes the device. This pin has a passive internal pull-down.
(Active High)
8
CS
Input
Chip Select
When this 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.
