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 (either directly,

or isolated through a diode), the BCMs will start simultane-

ously when enabled. The PC pin is capable of being either

driven high by 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

set point of ~3.0 V and an approximate gain of 10 mV/°C. It

can source up to 100 uA and may also be used as a “Power

Good” flag to verify that the BCM is operating.
