3.3.4. Ignition Control
The PIN 4 of power connector is Output 1 (Digital, Negative trigger). It is Open-Drain type
with no internal pull-up resistor which also be used to control a relay. It means that the user
has to provide a pull-up resistor or a relay coil to any positive voltage (32V max.) to detect an
inactive output by voltage. It can drive a continuous current of 0.2A.
The electrical conditions of it are:
Logical State Electrical State
Active <1.5V, max current is 0.2A
Inactive Open or the pull-up voltage
(max 32V)
User can use this pin to control a relay output. An example to control the ignition key is
showed in following figure. Please refer to chapter 3.4.5 for the detail information on how to
drive a relay with digital output.
