3.4.1.1. Low power, high-side output connections
You must be aware of the following when connecting the low power, high-side
outputs:
▪
the outputs are connected to the in5 Vdc supply through a pull-up
resistor. Each output is de-rated to 4.3 V. Maximum load on each output is
358 mA.
▪
the outputs can provide power to LED or other small loads in a vehicle.
When connecting the low power, high-side outputs, ensure you follow these best
practices:
▪
the outputs should not be connected to loads that will draw currents greater
than the maximum current.
▪
The grounds for the loads should be connected physically close to the PHD
power grounds.
