Ignition IGT I Do not add any voltage on it. There is
a built-in pull up resister, you can test
about 0.8V voltage on it.
¯¯|___|¯¯ low impulse width > 300ms
This signal switches the
module on. The IGT signal
characteristic is:
Power on triggered and
low level triggered. Fall
time should be <1ms.
Note: To turn on the mod-
ule please use an open-
drain/collector circuit.
Test point recommended.

EMERG_RST I Do not add any voltage on it. There is
a built-in pull up resistor to pull to GND
when Reset.
¯¯|___|¯¯ low impulse width > 200ms
This line must be driven
low by an open drain or
open collector driver con-
nected to GND.
If unused keep line open.
