Product details
Overview
IR7106SPBF from Infineon Technologies (formerly International Rectifier) is a 700V high- and low-side gate driver IC for N-channel IGBTs and MOSFETs in half-bridge configurations. It features independent HO/LO outputs, 220ns/200ns typical propagation delays, 200mA/350mA peak output current, and operates from -40°C to 125°C. Used in micro-inverter and servo motor drive stages where bootstrap-powered high-side switching up to 700V offset is required.
For engineers reviewing the IR7106SPBF datasheet, IR7106SPBF pinout, IR7106SPBF application, or IR7106SPBF equivalent, key selection criteria include VOFFSET ≤ 700V, matched tON/tOFF, UVLO thresholds on both VCC and VBS, logic compatibility down to 3.3V, and SOIC-8 package thermal performance under continuous switching.
Technical Context
The IR7106SPBF integrates two independent gate drivers - one floating HVIC channel for high-side operation referenced to VS, and one grounded channel referenced to COM. Its level-shifting architecture supports dV/dt immunity up to 50 V/ns and maintains logic integrity across VS offsets from –5 V to +700 V.
Proprietary latch-immune CMOS and HVIC processes enable robust operation with matched propagation delays (≤50 ns mismatch), undervoltage lockout on both VCC and VBS supplies, and pulsed output currents of 200 mA (source) and 350 mA (sink) into capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | ≤ 700 V - enables high-side switching in 600V-class inverters without external level shifters |
| tON/tOFF | 220 ns / 200 ns typ. - supports >1 MHz PWM switching with precise dead-time control |
| IO+/IO− | 200 mA / 350 mA typ. - drives 1–2 nF gate capacitances with <150 ns rise/fall times |
| VIN Logic Range | 3.3 V, 5 V, 15 V compatible - interfaces directly with MCU GPIO or isolated digital isolators |
| UVLO Thresholds | VCC: 8.2 V / VBS: 8.9 V with 0.7 V hysteresis - prevents erratic switching during bootstrap supply droop |
| TA Range | –40°C to +125°C - qualified for industrial motor drives and outdoor micro-inverters |
Pinout & Package
IR7106SPBF is housed in an 8-lead SOIC (SO8N) package with standard 1.27 mm pitch, rated for 200°C/W junction-to-ambient thermal resistance under board-mounted conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC | Low-side and logic supply input | Provides power for internal logic and LO driver; must be decoupled near pin |
| 2: HIN | High-side logic input | CMOS/LSTTL-compatible signal controlling HO output; referenced to COM |
| 3: LIN | Low-side logic input | CMOS/LSTTL-compatible signal controlling LO output; referenced to COM |
| 4: COM | Low-side return and logic ground | Reference node for VCC, HIN, LIN, and LO; must be low-inductance connection |
| 5: VB | High-side floating supply | Bootstrap-supplied voltage for HO driver stage; referenced to VS |
| 6: HO | High-side gate drive output | Drives gate of high-side N-channel device; referenced to VS |
| 7: VS | High-side floating return | Switching node connection for bootstrap capacitor and HO load; handles up to 700 V offset |
| 8: LO | Low-side gate drive output | Drives gate of low-side N-channel device; referenced to COM |
Key Features
| Feature | Design Value |
|---|---|
| Matched propagation delays | ≤50 ns max delay mismatch between HO and LO paths - simplifies dead-time tuning in three-phase inverters |
| Bootstrap-compatible floating channel | VS-referenced HVIC stage withstands –5 V to +700 V offset - eliminates need for isolated DC-DC supplies |
| Dual UVLO protection | Independent lockout on VCC and VBS with hysteresis - prevents shoot-through during supply transients |
| High dV/dt immunity | Rated for 50 V/ns common-mode transient - ensures reliable operation in noisy inverter bridge environments |
| Logic-level input compatibility | Operates with 3.3 V, 5 V, or 15 V logic - interfaces directly with microcontrollers, FPGAs, or digital isolators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844SPbF | Higher VOFFSET (600 V), slower tON/tOFF (340/230 ns), no VBS UVLO | Lacks independent VBS undervoltage detection - requires external monitoring for bootstrap health | Preferred when cost sensitivity outweighs need for VBS fault protection |
| ISO5852S | Reinforced isolation, 5.7 kVRMS, 1000 VPK working voltage, integrated isolated DC-DC | Eliminates bootstrap circuitry but increases BOM count and layout area | Chosen when system-level safety certification (IEC 61800-5-1) mandates galvanic isolation |
Compared with IRS21844SPbF and ISO5852S, IR7106SPBF offers optimal balance of 700 V capability, matched timing, and dual UVLO in a non-isolated SOIC-8 - ideal for cost-constrained, high-volume inverter designs where bootstrap reliability is critical.

FAQ
What is the maximum allowable dV/dt at the VS pin?
The IR7106SPBF is rated for 50 V/ns common-mode transient immunity at the VS pin. This specification ensures reliable operation during fast-switching events in inverter bridges, preventing false triggering or latch-up even when high di/dt induces large voltage spikes across parasitic inductances in the high-side source path.
Can IR7106SPBF drive SiC MOSFETs?
Yes - its 200 mA source / 350 mA sink peak output current and 220 ns turn-on time support gate driving of discrete 650 V SiC MOSFETs with Qg ≤ 25 nC. However, external negative gate voltage clamping is recommended for robust turn-off, as the IC does not provide active negative bias on HO/LO outputs.
Is a bootstrap diode required for normal operation?
Yes - a fast recovery or Schottky bootstrap diode (e.g., 1N4148W or PMEG4010AEB) is mandatory between VCC and VB to charge the bootstrap capacitor during LO conduction. The diode must support ≥25 V reverse voltage and ≤100 ns reverse recovery to prevent VBS droop during high-frequency switching.
Does IR7106SPBF include built-in shoot-through protection?
No - it lacks integrated logic-based dead-time insertion or cross-conduction prevention circuitry. Shoot-through mitigation must be implemented externally via MCU firmware dead-time generation, gate resistor tuning, or external logic. The matched propagation delays simplify this implementation but do not eliminate the requirement.
