Half Bridge Outputs (HBO)
Half Bridge Outputs are push-pull, pulse width
modulated (PWM) outputs. If not being used as
push-pull drivers, Half Bridge Outputs can be
used as generic high/low PWM outputs capable
of sinking 8A to ground and driving 8A to 12V up
to 2.2kHz.
HBOs can be used to control any push-pull type
device when used as generic high/low switched or
PWM outputs.
Half Bridge Outputs can be used as generic low-
side DPOs or to control devices such as high-side
driven solenoids, high side switched automatic
transmission solenoids, etc.
Specs:
• Overcurrent and Overtemperature Protection
• 0 to 27V voltage feedback
• High side current feedback
• Capable of 0-100% duty cycle
• 2.2kHz switching speed

VAREX ACTUATOR
In this mode the PD16 acts as a
peripheral device to provide the ECU
additional I/O (common on Nexus VCU
applications). The PD16 is switched on
and off via CAN power connection.
Ensure PD16 has battery power and
ground. The ignition switch will be
ignored, meaning pins A13 (Ign. Switch
Input) and A26 (Low Current Constant
12V) will not be used.
Connect the CAN power output from
your ECU or VCU directly to Pin A25
(CAN +12V “Wake-Up”) on the PD16.
This can be done using a standard
Haltech CAN cable as shown in the
diagram above.
