Ignition Control
Ignition control can be used to control the power ON/OFF function of the DC-DC charger.
In ignition ON mode, the DC-DC charger will only operate when the Ignition control signal is high. In this
mode, the DC-DC charger can operation from 9-32V input.
The ignition control mode will set to ON once ignition control pin is applied with 9-32V voltage. The ignition
control will remain in ON mode until it is manually reset.
Cancel Ignition Control
i) Disconnect Ignition pin.
ii) Press and hold button for around 15sec until A, B, C LED flashes.
iii) Release the button to finish the reset
Low Voltage Disconnect (LVD) and Recovery (LVR)
In ignition control OFF mode, the DC-DC charger will operate when input and output is connected. In this
mode, the DC-DC charger has Low Voltage Disconnect to protect main battery from over discharging. The
following table shows LVD and LVR status.
