B High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of bootstrap
diode and positive side of bootstrap capacitor to this pin. Internal charge pump supplies 30µA out of this pin to
maintain bootstrap supply. Internal circuitry clamps the bootstrap supply to approximately 12.8V.
B High-side Input. Logic level input that controls BHO driver (Pin 20). BLI (Pin 5) high level input overrides BHI high
level input to prevent half-bridge shoot-through, see Truth Table. DIS (Pin 3) high level input overrides BHI high level
input. The pin can be driven by signal levels of 0V to 15V (no greater than V
DISable input. Logic level input that when taken high sets all four outputs low. DIS high overrides all other inputs.
When DIS is taken low the outputs are controlled by the other inputs. The pin can be driven by signal levels of 0V to
15V (no greater than V
Chip negative supply, generally will be ground.
B Low-side Input. Logic level input that controls BLO driver (Pin 18). If BHI (Pin 2) is driven high or not connected
externally then BLI controls both BLO and BHO drivers, with dead time set by delay currents at HDEL and LDEL (Pin
8 and 9). DIS (Pin 3) high level input overrides BLI high level input. The pin can be driven by signal levels of 0V to 15V
(no greater than V
A Low-side Input. Logic level input that controls ALO driver (Pin 13). If AHI (Pin 7) is driven high or not connected
externally then ALI controls both ALO and AHO drivers, with dead time set by delay currents at HDEL and LDEL (Pin
8 and 9). DIS (Pin 3) high level input overrides ALI high level input. The pin can be driven by signal levels of 0V to 15V
(no greater than V
A High-side Input. Logic level input that controls AHO driver (Pin 11). ALI (Pin 6) high level input overrides AHI high
level input to prevent half-bridge shoot-through, see Truth Table. DIS (Pin 3) high level input overrides AHI high level
input. The pin can be driven by signal levels of 0V to 15V (no greater than V
High-side turn-on DELay. Connect resistor from this pin to V
both high-side drivers. The low-side drivers turn-off with no adjustable delay, so the HDEL resistor guarantees no
shoot-through by delaying the turn-on of the high-side drivers. HDEL reference voltage is approximately 5.1V.
Low-side turn-on DELay. Connect resistor from this pin to V
both low-side drivers. The high-side drivers turn-off with no adjustable delay, so the LDEL resistor guarantees no
shoot-through by delaying the turn-on of the low-side drivers. LDEL reference voltage is approximately 5.1V.
A High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of bootstrap
diode and positive side of bootstrap capacitor to this pin. Internal charge pump supplies 30µA out of this pin to
maintain bootstrap supply. Internal circuitry clamps the bootstrap supply to approximately 12.8V.
A High-side Output. Connect to gate of A High-side power MOSFET.
A High-side Source connection. Connect to source of A High-side power MOSFET. Connect negative side of
bootstrap capacitor to this pin.
A Low-side Output. Connect to gate of A Low-side power MOSFET.
A Low-side Source connection. Connect to source of A Low-side power MOSFET.
