Definition
1
FETIN
Input External FET Input This terminal 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 terminal has a passive internal pulldown.
3
RSTB
Input
Reset
This input wakes the device. It is also used to initialize the device configuration
and fault registers through SPI. This digital terminal has a passive internal
pulldown.
4
FLASHER
Input
Flasher Input
(Active High)
This input wakes the device. The Fail mode can be activated by this digital input.
This terminal has a passive internal pulldown.
5
CLOCK
Input
Clock Input
The PWM frequency and timing are generated from this digital clock input by
the PWM module. This terminal has an active internal pulldown current source.
6
LIMP
Input
Limp Home Input The Fail mode can be activated by this digital input. This terminal has an active
(Active High) internal pulldown current source.
7
NC
NC
No Connect
No internal connection to this terminal.
8
CS
Input
Chip Select
When this digital signal is high, SPI signals are ignored. Asserting this terminal
(Active Low) low starts an SPI transaction. The transaction is signaled as completed when
this signal returns high. This terminal has an active internal pullup current
source.
9
SCLK
Input
SPI Clock Input This digital input terminal is connected to the master microcontroller providing
the required bit shift clock for SPI communication. This terminal has an active
internal pulldown current source.
