Product details
Overview
ISL83202IBZ from Intersil is a 55V, 1A peak current H-bridge FET driver designed to independently control four N-channel MOSFETs in full-bridge or dual half-bridge configurations for medium-voltage motor and power conversion systems. It delivers 15ns (typ) rise/fall times into 1000pF loads, supports up to 200kHz switching, and features user-programmable dead time (0.1–4.5µs) via a single resistor.
For engineers reviewing the ISL83202IBZ datasheet, ISL83202IBZ pinout, ISL83202IBZ application, or ISL83202IBZ equivalent, key selection criteria include bootstrap voltage capability (70V max), shoot-through protection logic, -55°C to +125°C operating range, input compatibility with 5V–15V logic levels, and independent ALI/AHI/BLI/BHI control architecture enabling flexible PWM sequencing.
Technical Context
The ISL83202IBZ integrates two high-side level-shift drivers (AHB/AHS and BHB/BHS) and four gate drivers (ALO/AHO/BLI/BHO) with dedicated turn-on delay circuitry tied to the DEL pin. Its shoot-through prevention relies on input priority logic (e.g., ALI overrides AHI) and hardware-enforced dead time, not software timing.
Undervoltage protection operates at two thresholds: VDDUV+ (7.6V typ) and VHBUV (6.0V typ referenced to AHS/BHS), ensuring safe operation during bootstrap supply sag or main rail droop. The DIS pin provides synchronous global disable with bootstrap capacitor refresh-critical for fault recovery in UPS and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 1.0A (typ) - sufficient to drive 1000pF gate capacitance with 15ns edge rates at +50°C |
| Max Bootstrap Voltage | 70VDC - enables use with 55V bridge topologies while maintaining margin for transients |
| Dead Time Range | 0.1µs to 4.5µs - set by external DEL resistor; prevents shoot-through across both half-bridges |
| Propagation Delay | 25ns (lower), 55ns (upper) - ensures precise timing alignment between low- and high-side switching edges |
| Logic Input Range | 0V to 15V - compatible with 5V, 12V, and 15V controller outputs without level-shifting |
| Operating Temp Range | -55°C to +125°C - qualified for industrial, automotive under-hood, and telecom power applications |
| Supply Voltage (VDD) | +8.5V to +15V - powers logic and low-side drivers; decoupling required at Pin 12 |

Key Features
| Feature | Design Value |
|---|---|
| Independent 4-FET Control | Four logic inputs (ALI/AHI/BLI/BHI) enable arbitrary switch combinations except shoot-through-supports asymmetric PWM, phase-shifted, or biphase topologies |
| Hardware Dead-Time Programming | Single external resistor on DEL pin sets precise, temperature-stable dead time (0.1–4.5µs); eliminates firmware timing dependency |
| Bootstrap Refresh on Disable | DIS pin low state actively recharges AHB/BHB bootstrap capacitors-ensures reliable high-side turn-on after fault recovery |
| Two-Tier Undervoltage Lockout | VDDUV (7.6V typ) and VHBUV (6.0V typ) independently monitor main supply and floating high-side rails-prevents erratic switching during brownouts |
| Shoot-Through Prevention Logic | Hardwired input priority (e.g., ALI > AHI) and DIS override guarantee no simultaneous AHO/ALO or BHO/BLO activation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge FET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2110PbF | Higher 10V logic threshold; fixed 0.6µs dead time; no DEL pin programming; 200V high-side rating | Better suited for high-voltage (>100V) inverters but lacks fine dead-time tuning for low-latency motor control | Choose IR2110PbF only if 200V high-side rating is required and fixed dead time is acceptable |
| LM5109BMAX | Integrated bootstrap diode; 1.25A peak current; 50ns propagation delay; no independent BLI/BHI inputs (only IN+/IN-) | Optimized for simple half-bridge or synchronous buck; lacks full-bridge flexibility and input-level programmability of ISL83202IBZ | Choose LM5109BMAX for cost-sensitive, space-constrained half-bridge designs where full 4-input control is unnecessary |
Compared with IR2110PbF and LM5109BMAX, the ISL83202IBZ uniquely combines user-programmable dead time, independent four-input control, and 55V/70V voltage ratings-making it optimal for precision full-bridge motor drives and UPS systems demanding configurability and robustness.

FAQ
What is the maximum bootstrap voltage supported by the ISL83202IBZ?
The ISL83202IBZ supports a maximum bootstrap supply voltage of 70VDC on pins AHB and BHB. This rating allows safe operation in 55V bridge applications with margin for voltage spikes and ringing. Exceeding 70V risks damage to the internal level-shift circuitry. The device's absolute maximum AHB/BHB voltage is 65V under transient conditions, but continuous operation must remain within the 70V DC limit specified in the datasheet.
How does the DIS pin function in the ISL83202IBZ?
The DIS (Disable) pin on the ISL83202IBZ is an active-high input that overrides all other control signals (ALI, AHI, BLI, BHI) to force ALO, AHO, BLO, and BHO low simultaneously. When pulled low, DIS triggers automatic refresh of the AHB and BHB bootstrap capacitors-critical for restoring high-side drive capability after fault events. Propagation delays from DIS to output turn-off are 50ns (low-side) and 75ns (high-side) at +25°C.
Can the ISL83202IBZ drive both high-side and low-side N-channel MOSFETs in a single half-bridge?
Yes-the ISL83202IBZ is explicitly designed to drive high-side and low-side N-channel MOSFETs in each half-bridge leg. Pins AHB/AHS and BHB/BHS provide floating high-side supplies and source references, while ALO/AHO and BLO/BHO deliver gate drive to respective MOSFETs. External bootstrap diodes and capacitors are required per leg, and the device includes integrated shoot-through protection to prevent simultaneous conduction.
What is the purpose of the DEL pin on the ISL83202IBZ?
The DEL pin on the ISL83202IBZ sets the user-programmable dead time between high-side and low-side driver turn-on via an external resistor to VSS. This hardware-based delay prevents shoot-through by ensuring one FET is fully off before the complementary FET turns on. With RDEL = 100kΩ, dead time is 4.5µs (typ); reducing RDEL to 10kΩ lowers it to 0.5µs (typ). The DEL pin voltage remains ~VDD – 2V during operation.
Does the ISL83202IBZ include undervoltage protection, and how does it operate?
Yes-the ISL83202IBZ includes dual undervoltage lockout (UVLO): VDDUV monitors the VDD rail (7.6V typ turn-on, 7.1V typ turn-off), while VHBUV monitors the high-side floating supplies AHB/BHB relative to AHS/BHS (6.0V typ). Both thresholds include hysteresis to prevent oscillation during brownouts. If either condition is violated, all outputs are disabled until the supply recovers, protecting MOSFETs from partial enhancement.
