THREE-PHASE POWER MOSFET CONTROLLER
PIN DESCRIPTIONS (continued)
VREG.
Regulated 13 V output supply for low side gate
drive and bootstrap capacitor charge circuit. It is good
practice to connect a decoupling capacitor from this pin to
AGND, as close to the device pins as possible. Pin should be
shorted to VBB for 12V applications.
V
BB
.
Motor power
supply connection for A3932 and power
MOSFETs. Pin should be shorted to VREG for 12V
applications.
REF.
Analog input to current limit comparator. Voltage
applied here sets the peak load current according to the
equation:
I
TRIP
= V
REF
/R
SENSE
LCAP.
5V reference to power internal logic, connection for
decoupling cap. This pin requires 1nF external capacitor for
decoupling and should not be used to power any external
circuitry.
DEAD.
Analog input. A resistor between DEAD and LCAP
is selected to adjust turn-off to turn-on time. This delay is
needed to prevent shoot-thru in the external power FET’s.
The resistor allowable range is 5.6k to 470k, which converts
to deadtime of 100ns to 5500ns.

11e-12 * R
DEAD
AGND.
Analog reference.
PGND.
Return for low side gate drive. This should be
connected to PCB power ground.
