Description

High Current Pulse Width Modulated (HPWMOUT/DOUT)

High current proportional outputs are unique to the MCO38-010 controller. These outputs are PWM, with
PWM frequency user-configurable using PLUS+1 GUIDE.
The MC038-010 has two types of high current PWM outputs: Paired bi-directional PWMs (10 A) that can
be configured as either H bridges or independent outputs and sourcing only PWMs (one 10 A and six 6
A). See the product data sheet and API documents for pair assignments.
All high current proportional outputs are operated as open loop. The controller kernel does, however,
monitor current for circuit protection, but there is no current feedback to the application. The output is a
constant voltage and not a constant current. PWM outputs are hardware protected from short or over
current.

MC038-010, MC088-XXX Output Pin Power Supply

The output pin power supply design of the MC038-010 and MC088-XXX controllers is different from that
of other PLUS+1 modules. MC038-010 and MC088-XXX controllers have discrete power supply planes for
output pins and a separate dedicated power supply for the DSP. Each output pin is associated with a
specific power supply plane. Refer to the controller data sheets for a map of outputs and their associated
power plane.
The controller DSP will be powered if power is supplied to any one of the controller's power planes.
