10 / 38 page BCM® in a VIA Package Rev 1.1 vicorpower.com Page 10 of 38 05/2016 800 927.9474 BCM3814x60E10A5yzz Signal Characteristics Specifications apply over all line and load conditions, unless otherwise noted; Boldface specifications apply over the temperature range of -40°C ≤ TCASE ≤100°C (T-Grade); All other specifications are at TCASE = 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 tied to the chassis. EXT. BIAS (VDDB) Pin • 5V supply input, required to power the circuitry internal to the BCM in a VIA package for communication signals such as SCL, SDA, ADDR etc • Voltage to EXT BIAS pin is needed for PMBus™ enable and disable control. It is not needed for PMBus monitoring voltage, current, power or temperature. Lower voltage is better. It will help to lower the power dissapation in the internal regulator that is generating 3.3V voltage for communication circuits. • Apply voltage to this pin between 4.5V and 9V. The nominal voltage is 5V.

Bias (VDDB) pin. • All input and output signals (SCL, SDA, ADDR) are referenced to SGND pin. Address (ADDR) Pin • This pin programs only a Fixed and Persistent slave address for BCM in a VIA package. • This pin programs the address using a resistor between ADDR pin and signal ground. • The address is sampled during startup and is used until power is reset. • This pin has 10kΩ pullup resistor internally between ADDR pin and internal VDD. • 16 addresses are available. Relative to nominal value of internal VDD (VVDD_NOM = 3.3V), a 206.25mV range per address.
