Product details
Overview
IRS21962STRPBF from Infineon Technologies (formerly International Rectifier) is a dual-channel high-side gate driver IC designed to independently drive two N-channel power MOSFETs or IGBTs in high-voltage half-bridge configurations. It features 600 V offset voltage capability, 500 mA peak output current per channel, 90 ns typical propagation delay, and 5 V CMOS/LSTTL-compatible Schmitt-trigger inputs with internal pull-down resistors. It is used in industrial motor drives and resonant DC-DC converters operating up to 200 kHz.
For engineers reviewing the IRS21962STRPBF datasheet, IRS21962STRPBF pinout, IRS21962STRPBF application, or IRS21962STRPBF equivalent, key selection criteria include floating channel dV/dt immunity (50 V/ns), matched propagation delay between channels, undervoltage lockout thresholds for VDD (4.0 V), VCC (7.5 V), and VB (7.5 V), and SOIC-16 narrow-body package compatibility with high-density PCB layouts.
Technical Context
The IRS21962STRPBF integrates two independent high-side drivers using proprietary HVIC technology, enabling operation with VS pins referenced up to 600 V above COM ground. Each channel includes dedicated bootstrap supply monitoring (VBSUV+ = 7.5 V typ), logic-level input stage with hysteresis, and matched propagation delay (±5 ns typical part-to-part matching).
It supports simultaneous high-side switching of two power switches without cross-conduction risk, thanks to integrated dead-time control via external RC networks and robust noise immunity against –Vs spikes and fast dVs/dt transients (50 V/ns). The device requires separate low-side supply (VCC = 10–20 V) and logic supply (VDD–VSS = 4.5–5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 600 V - maximum voltage difference between VS and COM, enabling direct high-side drive in 400 V DC bus systems |
| IO+, IO− (typ) | 0.5 A - peak pulsed output current per channel, sufficient to charge/discharge 1000 pF gate capacitance in <100 ns |
| tON, tOFF (typ) | 90 ns - propagation delay ensures precise timing control in 200 kHz PWM applications |
| VDD Input Range | 4.5–5.5 V - compatible with standard 5 V logic families without level shifting |
| dVS/dt Immunity | 50 V/ns - prevents false triggering during fast high-side switching transitions |
| UVLO Thresholds | VDDUV+ = 4.0 V, VCCUV+ = 7.5 V, VBSUV+ = 7.5 V - independent undervoltage lockouts prevent erratic gate drive during supply brownouts |
Pinout & Package
IRS21962STRPBF is housed in a 16-lead narrow-body SOIC package (SOIC-16N), RoHS-compliant, with moisture sensitivity level MSL2 (260 °C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side supply input | Provides power to internal logic and level-shift circuitry; must be 10–20 V referenced to COM |
| VDD | Logic supply positive | 5 V logic rail input referenced to VSS; powers input buffer and digital control block |
| VSS | Logic supply return | Reference node for HIN1/HIN2 inputs; may float up to 600 V above COM |
| HIN1, HIN2 | Digital input pins | CMOS Schmitt-trigger inputs with internal pull-down; accept 0–5 V logic signals referenced to VSS |
| HO1, HO2 | High-side gate drive outputs | Floating outputs referenced to VS1/VS2; drive N-MOSFET gates with 0.5 A peak sink/source |
| VB1, VB2 | Bootstrap supply inputs | Positive rails for high-side driver stages; require external bootstrap capacitors tied to VS1/VS2 |
| VS1, VS2 | Floating source references | Return nodes for respective high-side channels; tolerate −5 V to +600 V relative to COM |
| COM | Common ground reference | System ground for low-side circuitry and VCC supply; not connected to VS or VSS |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side outputs | Enables synchronous control of two high-side switches in multi-phase topologies without shared timing constraints |
| Propagation delay matching | ≤5 ns typical channel-to-channel skew ensures balanced dead-time management in half-bridge pairs |
| Integrated UVLO on VDD, VCC, and VB supplies | Prevents partial turn-on by disabling outputs when any supply falls below safe threshold |
| 50 V/ns dVS/dt immunity | Eliminates need for external noise filtering on VS pins in high-dV/dt environments like PFC stages |
| CMOS/LSTTL-compatible inputs with hysteresis | Accepts industry-standard logic levels and rejects noise-induced glitches on HIN lines |
Applications
| Industrial Motor Drives | Resonant DC-DC Converters |
|---|---|
Use Scenario: Three-phase inverter driving BLDC or induction motors in HVAC compressors and pump controllers. IC Role / Device Role / Timing Role: High-side gate driver for upper-leg N-MOSFETs in each phase leg, synchronized with complementary low-side drivers. Use Value: 600 V offset rating supports 400 V DC bus operation; matched propagation delays ensure consistent phase timing and reduced torque ripple. | Use Scenario: LLC resonant converter in telecom rectifiers and server PSUs requiring zero-voltage switching. IC Role / Device Role / Timing Role: Dual high-side driver controlling two primary-side MOSFETs in asymmetrical half-bridge configuration. Use Value: 90 ns propagation delay enables precise 200 kHz switching; dV/dt immunity maintains reliability during hard-switching transients. |
| Solar Microinverters | Induction Heating Systems |
Use Scenario: Single-phase grid-tied inverter converting PV panel DC to 230 V AC with transformerless topology. IC Role / Device Role / Timing Role: High-side driver for split-phase H-bridge output stage, paired with isolated low-side drivers. Use Value: VSS-referenced inputs simplify isolated gate drive design; 5 V logic compatibility reduces auxiliary supply complexity. | Use Scenario: Medium-frequency (20–100 kHz) series-resonant inverter powering induction cooktops and industrial heating coils. IC Role / Device Role / Timing Role: Dual-channel driver managing upper switches in full-bridge topology with variable frequency control. Use Value: Independent UVLO per channel prevents shoot-through during thermal derating; SOIC-16N footprint allows compact heatsink-integrated layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844STRPBF | Single high-side + single low-side output; no dual high-side configuration; lower VOFFSET (600 V same), but lacks second floating channel | Requires external level-shifting for second high-side switch; suitable only for half-bridge, not dual high-side topologies | Select when cost-sensitive half-bridge designs dominate and dual independent high-side control is unnecessary |
| IR2110STRPBF | Higher propagation delay (120 ns typ); no built-in VDD UVLO; requires external logic supply decoupling; same SOIC-16N package | Lacks integrated logic supply monitoring; less robust in noisy industrial environments with fluctuating VDD | Choose where legacy design reuse is prioritized and system-level UVLO is already implemented externally |
Compared with IRS21844STRPBF and IR2110STRPBF, the IRS21962STRPBF uniquely delivers dual independent high-side drive with matched timing, integrated triple UVLO, and superior dV/dt immunity-making it optimal for multi-phase, high-reliability, and space-constrained high-voltage applications.

FAQ
What is the maximum allowable dV/dt on the VS pins?
The IRS21962STRPBF is rated for 50 V/ns dVS/dt and dVSS/dt transients relative to COM. This specification is validated per JEDEC standards and ensures reliable operation without false triggering during fast high-side switching events in 400 V bus applications.
Can HIN1 and HIN2 be driven from the same logic signal?
Yes - HIN1 and HIN2 accept identical 5 V logic inputs referenced to VSS, but they control independent high-side outputs (HO1 and HO2). Driving both from one source configures synchronous dual high-side switching, useful in paralleled or interleaved topologies.
Is an external bootstrap diode required for VB1 and VB2?
Yes - each VB pin requires an external fast recovery bootstrap diode (e.g., 1N4148 or equivalent) and capacitor (typically 0.1–1 µF ceramic) to sustain the floating high-side supply during continuous conduction. The diode must withstand ≥600 V reverse voltage and support ≥100 mA average current.
Does the device support 3.3 V logic inputs?
No - the input threshold is defined for 5 V logic: VIN,th+ = 3.5 V min and VIN,th− = 0.6 V max. A 3.3 V signal may not reliably exceed the high-threshold margin and risks incomplete turn-on; level-shifting to 5 V is required for guaranteed operation.
