Control Pin Specifications
See Using the Control Signals PC, TM for more information.
PC (BCM Primary Control)
The PC pin can enable and disable the BCM module. When held
below V_{PC_DIS} the BCM shall be disabled. When allowed to
float with an impedance to –IN of greater than 50kΩ the
module will start. When connected to another BCM PC pin
(either directly, or isolated through a diode), the BCM modules
will start simultaneously when enabled. The PC pin is capable of
being either driven high by an external logic signal or internal
pull up to 5V (operating).
TM (BCM Temperature Monitor)
The TM pin monitors the internal temperature of the BCM module
within an accuracy of ±5°C. It has a room temperature setpoint of
~3.0V and an approximate gain of 10mV/°C. It can source up to
100µA and may also be used as a “Power Good” flag to verify that
the BCM module is operating.
