BCM380y475x800A31
Reported Characteristics
Specifications apply over all line, load conditions, unless otherwise noted; Boldface specifications apply over the temperature range of -40°C ≤ TINTERNAL
≤ 125°C (T-Grade); All other specifications are at TINTERNAL = 25ºC unless otherwise noted.
Monitored Telemetry
• The BCM communication version is not intended to be used without a Digital Supervisor.

Variable Parameter
• Factory setting of all below Thresholds and Warning limits are 100% of listed protection values.
• Variables can be written only when module is disabled either EN pulled low or VIN < VIN_UVLO-
.
• Module must remain in a disabled mode for 3 ms after any changes to the below variables allowing ample time to commit changes to EEPROM.
