Signal Characteristics
Specifications apply over all line and load conditions, unless otherwise noted;
boldface
specifications apply over the temperature range of
-40°C
≤

CASE
≤
100°C (T-Grade); all other specifications are at T
CASE
= 25ºC unless otherwise noted.
Primary Control: PC
• The PC pin enables and disables the BCM. When held low, the BCM is disabled.
• In an array of BCM modules, PC pins should be interconnected to synchronize start up and permit start up into full load conditions.
• PC pin outputs 5V during normal operation. PC pin internal bias level drops to 2.5V during fault mode, provided V
IN
remains
in the valid range.

Temperature Monitor: TM
• The TM pin monitors the internal temperature of the controller IC within an accuracy of ±5°C.
• Can be used as a “Power Good” flag to verify that the BCM module is operating.
• Is used to drive the internal comparator for Overtemperature Shutdown.
