CONTROL PIN SPECIFICATIONS

See section 5.0 for further application details and guidelines

.

The PC pin can enable and disable the BCM. When held below

an impedance to –IN of greater than 50 k

Ω the module will

start. When connected to another BCM PC pin, the BCMs will

start simultaneously when enabled. The PC pin is capable of

being driven high by either an external logic signal or internal

pull up to 5 V (operating).

The TM pin monitors the internal temperature of the BCM

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 BCM is operating.
