PC (BCM® Primary Control)
The PC pin can enable and disable the BCM™ bus converter.
When held below VPC_DIS the BCM module shall be disabled.
When allowed to float with an impedance to –IN of greater
than 50 kΩ the module will start. When connected to another
bus converter PC pin, the modules will start simultaneously
when enabled. The PC pin is capable of being driven high by
an either external logic signal or internal pull up to 5 V (operat-
ing).

The TM pin monitors the internal temperature of the module
within an accuracy of +5/-5 °C. It has a room temperature
setpoint of ~3.0 V and an approximate gain of 10 mV/°C. It
can source up to 100 µA and may also be used as a “Power
Good” flag to verify that the bus converter is operating.
