PRELIMINARY DATASHEET
7.0 USING THE CONTROL SIGNALS PC, TM
Primary Control (PC) pin can be used to accomplish the
following functions:
• Logic enable and disable for module: Once T on1 time has
• Auxiliary voltage source: Once enabled in regular
• Synchronized start up: In an array of parallel modules, PC
• Output disable: PC pin can be actively pulled down in order
• Fault detection flag: The PC 5 V voltage source is internally
• Note that PC can not sink significant current during a fault
Temperature Monitor (TM) pin provides a voltage
proportional to the absolute temperature of the converter
control IC.
It can be used to accomplish the following functions:
• Monitor the control IC temperature: The temperature in
• Fault detection flag: The TM voltage source is internally

been satisfied, a PC voltage greater than Vpc_en will cause
the module to start. Bringing PC lower than Vpc_dis will
cause the module to enter standby.
operational conditions (no fault), each BCM module
PC provides a regulated 5 V, 3.5 mA voltage source.
pins should be connected to synchronize start up across
units. This permits the maximum load and capacitance
to scale by the number of paralleled modules.
to disable the module. Pull down impedance shall be lower
than 60 Ω.
turned off as soon as a fault is detected.
condition. The PC pin of a faulted module will not cause
interconnected PC pins of other modules to be disabled.
Kelvin is equal to the voltage on the TM pin scaled
by 100. (i.e. 3.0 V = 300 K = 27ºC). If a heat sink is applied,
TM can be used to protect the system thermally.
turned off as soon as a fault is detected. For system
monitoring purposes microcontroller interface faults are
detected on falling edges of TM signal.
