PMBus™ Reported Characteristics
Specifications apply over all line and load conditions, unless otherwise noted; Boldface specifications apply over the temperature range of -40°C ≤ T_CASE
≤100°C (T-Grade); All other specifications are at T_CASE = 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 V_HI < V_{HI_UVLO-}.
• Module must remain in a disabled mode for 3ms after any changes to the below variables allowing ample time to commit changes to EEPROM.
