BCM4414xD1E13A2yzz
Signal 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. Please Note: For chassis mount model, Vicor part number 42550 will be
needed for applications requiring the use of the signal pins. Signal cable 42550 is rated up to five insertions and extractions. To avoid unnecessary stress on the
connector, the cable should be appropriately strain relieved.
EXT. BIAS (VDDB) Pin
• VDDB powers the internal controller.
• VDDB needs to be applied to enable and disable the BCM through PMBus™ control (using OPERATION COMMAND), and to adjust warning and
protection thresholds.
• VDDB voltage not required for telemetry; however, if VDDB is not applied, telemetry information will be lost when V_IN is removed.

SGND Pin
• All PMBus signals (SCL, SDA, ADDR) are referenced to SGND pin.
• SGND pin also serves as return pin (ground pin) for VDDB.
• Keep SGND signal separated from the low voltage side power return terminal (–LO) in electrical design.
Address (ADDR) Pin
• This pin programs the address using a resistor between ADDR pin and signal ground.
• The address is sampled during startup and is stored until power is reset. This pin programs only a Fixed and Persistent address.
• This pin has an internal 10kΩ pullup resistor to 3.3V.
• 16 addresses are available. The range of each address is 206.25mV (total range for all 16 addresses is 0V to 3.3V).
