Functional Pin Description
VCC (Pin 8)
Bias supply for the IC’s small-signal circuitry. Connect this
pin to a 5V supply and locally decouple using a quality 0.1 μ F
ceramic capacitor.
PVCC (Pin 16)
Power supply pin for the MOSFET drives. Connect this pin to
a 5V supply and locally decouple using a quality 1 μ F
ceramic capacitor.

t FUGATE
t RLGATE
t PDHLGATE
GND and PGND (Pins 25 and 14)
Connect these pins to the circuit ground using the shortest
possible paths. All internal small-signal circuitry is
referenced to the GND pin. LGATE drive is referenced to the
PGND pin.
VID0-4 (Pins 2, 1, 24-22)
Voltage identification inputs from microprocessor. These pins
respond to TTL logic thresholds. The ISL6315 decodes the
VID inputs to establish the output voltage; see VID Tables for
correspondence between DAC codes and output voltage
settings. These pins are internally pulled high, to
approximately 1.2V, by 40 μ A (typically) internal current
