Product details
Overview
IRS21962SPBF 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 rating, 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 where high dV/dt immunity and matched channel timing are critical.
For engineers reviewing the IRS21962SPBF datasheet, IRS21962SPBF pinout, IRS21962SPBF application, or IRS21962SPBF equivalent, key selection considerations include floating channel voltage tolerance (600 V), propagation delay matching between HO1/HO2 outputs, undervoltage lockout thresholds for VDD (4.0 V/3.9 V), VCC (7.5–9.7 V), and VBS (7.5–9.4 V), and SOIC-16N package thermal resistance (100 °C/W).
Technical Context
The IRS21962SPBF integrates two independent high-side drivers using proprietary HVIC technology, enabling operation with VS nodes up to 600 V above COM ground. Each channel includes matched propagation delay paths, dedicated bootstrap supply monitoring (VBSUV+/-), and latch-immune logic to withstand fast transients (dVS/dt ≤ 50 V/ns).
It accepts standard 5 V logic inputs referenced to VSS, supports simultaneous or independent control of two high-side switches, and incorporates separate undervoltage lockout circuits for VDD, VCC, and VBx supplies-ensuring safe turn-off during supply brownout conditions across all domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 600 V - Maximum allowable potential difference between VS and COM, enabling direct high-side switching in 400 V DC bus systems. |
| IO+, IO− (typ) | 500 mA - Peak pulsed output current per channel, sufficient to charge/discharge 1000 pF gate capacitance within 90 ns. |
| tON, tOFF (typ) | 90 ns - Propagation delay from HIN to HO, tightly matched between channels for synchronous half-bridge timing control. |
| VDD UV Threshold | 4.0 V (rising), 3.9 V (falling) - Ensures reliable logic input rejection below valid 5 V CMOS levels, preventing spurious switching. |
| VBS UV Threshold | 7.5–9.4 V - Bootstrap supply monitoring window prevents HO output activation unless gate drive voltage meets minimum regulation margin. |
| Package Thermal RθJA | 100 °C/W - Junction-to-ambient resistance in SOIC-16N package; limits continuous power dissipation to ~1 W at TA = 25°C. |
Pinout & Package
IRS21962SPBF is housed in a 16-lead narrow-body SOIC (SOIC-16N) package with exposed pad for thermal enhancement. Pin assignments follow JEDEC MS-012AC standard, with dual high-side outputs (HO1/HO2), floating supply inputs (VB1/VB2, VS1/VS2), logic inputs (HIN1/HIN2), and low-side supply (VCC, COM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side logic supply | Provides 10–20 V bias for internal level-shifting and logic circuitry; referenced to COM. |
| COM | Low-side reference ground | Common return for VCC and logic inputs; must be connected to system low-side DC bus (e.g., −200 V rail). |
| HIN1, HIN2 | Digital logic inputs | CMOS/LSTTL-compatible Schmitt-trigger inputs with internal pull-down; tolerate VSS offset up to 600 V. |
| HO1, HO2 | High-side gate drive outputs | Floating outputs capable of sourcing/sinking 500 mA; swing from VSx to VBx (10–20 V range). |
| VB1, VB2 | Floating high-side supply rails | Bootstrap or isolated supplies powering upper gate drivers; each referenced to its respective VSx node. |
| VS1, VS2 | Floating high-side return nodes | Return paths for VB1/VB2; track source/emitter potentials of driven MOSFETs/IGBTs up to 600 V above COM. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side outputs | Enables synchronous or asymmetric control of two high-side switches without shared timing constraints or cross-conduction risk. |
| Propagation delay matching | Ensures <±10 ns skew between HO1 and HO2 edges under identical load and supply conditions-critical for ZVS/ZCS topologies. |
| 50 V/ns dVS/dt immunity | Prevents false triggering during fast high-side switching transitions in hard-switched or resonant converters. |
| Separate VDD/VCC/VBS UVLO | Independent lockout circuits prevent unsafe operation if any supply rail falls outside defined functional window. |
| Internal input pull-down resistors | Guarantees defined logic-low state on HIN pins during MCU reset or unpowered states-eliminates need for external biasing. |
Applications
| Industrial Motor Drives | Resonant DC-DC Converters |

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 |
|---|---|---|---|
| IR2110PbF | Single high-side + single low-side output; no propagation delay matching; lower VOFFSET (500 V); SOIC-14 package. | Requires external level-shifting for dual high-side use; unsuitable for precision timing-critical half-bridges. | Select when cost-sensitive designs require basic high/low-side pairing and timing skew is not critical. |
| UCC27211D | 600 V VOFFSET; dual high-side only; 4 A peak output; 15 ns propagation delay; thermally enhanced SOIC-8 package. | Higher drive strength and faster switching, but lacks independent VBS UVLO and dV/dt immunity specs beyond 25 V/ns. | Select when gate charge requirements exceed 500 mA and layout space is constrained-requires careful noise filtering on VS nodes. |
Compared with IR2110PbF and UCC27211D, IRS21962SPBF uniquely balances dual high-side independence, 600 V robustness, matched timing, and comprehensive supply monitoring-making it optimal for industrial inverters requiring long-term reliability under harsh transient conditions.

FAQ
What is the maximum allowable dVS/dt for IRS21962SPBF?
The IRS21962SPBF is rated for up to 50 V/ns dVS/dt on both VS1 and VS2 pins relative to COM. This specification is verified per datasheet test conditions and ensures reliable operation without false triggering during fast high-side switching transitions in hard-switched or resonant topologies.
Can IRS21962SPBF drive IGBTs directly?
Yes-IRS21962SPBF is explicitly qualified to drive N-channel IGBTs in high-side configurations. Its 500 mA peak output current, 10–20 V output swing, and 600 V offset rating meet typical IGBT gate drive requirements for devices rated up to 600 V collector-emitter voltage.
Does IRS21962SPBF require external bootstrap diodes?
Yes-external fast-recovery bootstrap diodes (e.g., 1N4148WS or equivalent) are required between VBx and VSx pins to recharge the bootstrap capacitors during each switching cycle. The IC does not integrate these diodes; their selection impacts minimum duty cycle and high-frequency stability.
Is there an evaluation board available for IRS21962SPBF?
No official Infineon evaluation board is designated solely for IRS21962SPBF. However, it is implemented on multi-driver reference designs such as IRPLVF510 (LLC resonant controller platform), where its dual high-side functionality is validated in 200 kHz operation with 600 V bus voltage.
