March 1995
80V, 1.25A Peak Current H-Bridge FET Driver
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 4.5s) making it ideal for switching frequencies up to 200kHz. The HIP4082 does not contain an internal charge pump, but does incorporate nonlatching 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.
Features
* Independently Drives 4 N-Channel FET in Half Bridge or Full Bridge Configurations * Bootstrap Supply Max Voltage to 95VDC * Drives 1000pF Load in Free Air at 50oC with Rise and Fall Times of Typically 15ns * User-Programmable Dead Time (0.1 to 4.5s) * DIS (Disable) Overrides Input Control and Refreshes Bootstrap Capacitor when Pulled Low * Input Logic Thresholds Compatible with 5V to 15V Logic Levels * Shoot-Through Protection * Undervoltage Protection
Applications
* UPS Systems * DC Motor Controls * Full Bridge Power Supplies * Class D Audio Power Amplifiers * Noise Cancellation Systems * Battery Powered Vehicles * Peripherals * Medium/Large Voice Coil Motors

HIP4082 Pin Descriptions
PIN NUMBER 1 SYMBOL BHB DESCRIPTION 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. B High-side Input. Logic level input that controls BHO driver (Pin 16). BLI (Pin 3) high level input overrides 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 100A 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. B Low-side Input. Logic level input that controls BLO driver (Pin 14). 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 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 100A pull-up to VDD will hold BLI high if this pin is not driven. 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 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 100A pull-up to VDD will hold ALI high if this pin is not driven. Turn-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. Chip negative supply, generally will be ground. A High-side Input. Logic level input that controls AHO driver (Pin 10). ALI (Pin 4) high level input overrides 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 100A 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. 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 VDD). An internal 100A pull-up to VDD will hold DIS high if this pin is not driven. 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. 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. Positive supply to control logic and lower gate drivers. De-couple this pin to VSS (Pin 6). A Low-side Output. Connect to gate of A Low-side power MOSFET. B Low-side Output. Connect to gate of B Low-side power MOSFET. B High-side Source connection. Connect to source of B High-side power MOSFET. Connect negative side of bootstrap capacitor to this pin. B High-side Output. Connect to gate of B High-side power MOSFET.
