Control Pin Functions
VC – VTM Control
The VC port is multiplexed. It receives the initial V
CC
voltage from an
upstream PRM, synchronizing the output rise of the VTM with the
output rise of the PRM. Additionally, the VC port provides feedback to
the PRM to compensate for the VTM output resistance. In typical
applications using VTMs powered from PRMs, the PRM’s VC port
should be connected to the VTM VC port.
In applications where a VTM is being used without a PRM, 14 V must
be supplied to the VC port for as long as the input voltage is below 26 V
and for 10 ms after the input voltage has reached or exceeded 26 V. The
VTM is not designed for extended operation below 26 V. The VC port
should only be used to provide V
CC
voltage to the VTM during startup.
PC – Primary Control
The Primary Control (PC) port is a multifunction port for controlling the
VTM as follows:
Disable – If PC is left floating, the VTM output is enabled. To
disable the output, the PC port must be pulled lower than 2.4 V,
referenced to -In. Optocouplers, open collector transistors or relays
can be used to control the PC port. Once disabled, 14 V must be
re-applied to the VC port to restart the VTM.
Primary Auxiliary Supply – The PC port can source up to 2.4 mA
