Description
The HIP4082 is a medium frequency, medium voltage
H-Bridge N-Channel MOSFET driver IC, available in 16 lead
plastic SOIC (N) and DIP packages.
Specifically targeted for PWM motor control and UPS applications, bridge based designs are made simple and flexible
with the HIP4082 H-bridge driver. With operation up to 80V,
the device is best suited to applications of moderate power
levels.
Similar to the HIP4081, it has a flexible input protocol for
driving every possible switch combination except those
which would cause a shoot-through condition. The
HIP4082’s reduced drive current allows smaller packaging
and it has a much wider range of programmable dead times
(0.1 to 4.5µs) making it ideal for switching frequencies up to
200kHz. The HIP4082 does not contain an internal charge
pump, but does incorporate non-latching level-shift translation control of the upper drive circuits.
This set of features and specifications is optimized for applications where size and cost are important. For applications
needing higher drive capability the HIP4080A and HIP4081A
are recommended.

Pin Descriptions
PIN
NUMBERSYMBOLDESCRIPTION
1BHBB High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of boot-
strap diode and positive side of bootstrap capacitor to this pin.
2BHIB High-side Input. Logic lev el input that controls BHO driver (Pin 16). BLI (Pin 3) high le v el input ov errides BHI
high level input to prevent half-bridge shoot-through, see Truth Table. DIS (Pin 8) high level input overrides
BHI high level input. The pin can be driven by signal levels of 0V to 15V (no greater than VDD). An internal
100µA pull-up to VDD will hold BHI high, so no connection is required if high-side and low-side outputs are to
be controlled by the low-side input.
3BLIB Low-side Input. Logic level input that controls BLO driver (Pin 14). If BHI (Pin 2) is driven high or not con-
nected externally then BLI controls both BLO and BHO drivers, with dead time set by delay currents at DEL
(Pin 5). DIS (Pin 8) high level input overrides BLI high level input. The pin can be driven by signal levels of 0V
to 15V (no greater than VDD). An internal 100µA pull-up to VDD will hold BLI high if this pin is not driven.
4ALIA Low-side Input. Logic level input that controls ALO driver (Pin 13). If AHI (Pin 7) is driven high or not con-
nected externally then ALI controls both ALO and AHO drivers, with dead time set by delay currents at DEL
(Pin 5). DIS (Pin 8) high level input overrides ALI high level input. The pin can be driven by signal levels of 0V
to 15V (no greater than VDD). An internal 100µA pull-up to VDD will hold ALI high if this pin is not driven.
5DELTurn-on DELay. Connect resistor from this pin to VSS to set timing current that defines the dead time between
drivers. All drivers turn-off with no adjustable delay, so the DEL resistor guarantees no shoot-through by delaying the turn-on of all drivers. The voltage across the DEL resistor is approximately Vdd -2V.
6VSSChip negative supply, generally will be ground.
7AHIA High-side Input. Logic lev el input that controls AHO driver (Pin 10). ALI (Pin 4) high le v el input ov errides AHI
high level input to prevent half-bridge shoot-through, see Truth Table. DIS (Pin 8) high level input overrides
AHI high level input. The pin can be driven by signal levels of 0V to 15V (no greater than VDD). An internal
100µA pull-up to VDD will hold AHI high, so no connection is required if high-side and low-side outputs are to
be controlled by the low-side input.
8DISDISable input. Logic level input that when taken high sets all four outputs low. DIS high overrides all other in-
puts. 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 VDD). An internal 100µA pull-up to VDD will hold DIS high if this pin is not
driven.
9AHBA High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of boot-
strap diode and positive side of bootstrap capacitor to this pin.
10AHOA High-side Output. Connect to gate of A High-side power MOSFET.
11AHSA High-side Source connection. Connect to source of A High-side power MOSFET. Connect negative side of
bootstrap capacitor to this pin.
