Product details
Overview
IR2101PBF from Infineon Technologies is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (HO) and low-side (LO) outputs with in-phase logic inputs, 600 V offset capability, 160 ns turn-on / 150 ns turn-off propagation delay, and 10–20 V gate drive supply range - used in half-bridge motor control and SMPS power stages.
For engineers reviewing the IR2101PBF datasheet, IR2101PBF pinout, IR2101PBF application, or IR2101PBF equivalent, key selection criteria include bootstrap-compatible high-side operation up to +600 V, matched channel delays (<50 ns), 3.3V/5V/15V logic compatibility, undervoltage lockout thresholds (8.2–9.8 V on VCC), and SOIC-8/PDIP-8 package options.
Technical Context
The IR2101PBF integrates a high-voltage level-shifting circuit for the floating high-side channel and a robust CMOS logic interface with latch-immune HVIC technology. It supports bootstrap-based high-side drive with VS referenced to COM and VB supplying the high-side gate driver stage.
Its dual-output architecture delivers simultaneous in-phase HIN→HO and LIN→LO switching with precise timing control: propagation delays are characterized at VS = 0 V (ton) and VS = 600 V (toff), and delay matching between channels is guaranteed ≤50 ns under 15 V bias and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 600 V - enables high-side switch operation in half-bridge topologies up to 600 V bus voltage |
| IO+ / IO− | 130 mA / 270 mA - peak source/sink current sufficient to drive 1 nF gate capacitance with <100 ns rise/fall |
| ton / toff (typ.) | 160 ns / 150 ns - ensures tight PWM timing control in >100 kHz switching applications |
| Delay matching | ≤50 ns - minimizes shoot-through risk in synchronous bridge configurations |
| VCC supply range | 10–20 V - compatible with standard 12 V or 15 V gate driver rails |
| Logic input compatibility | 3.3 V, 5 V, 15 V - interoperable with microcontrollers, FPGAs, and analog comparators without level shifting |
| VCC UVLO threshold | 8.2–9.8 V (rising), 7.4–9.0 V (falling) - prevents erratic output behavior during brown-out conditions |
Pinout & Package
IR2101PBF is available in 8-lead PDIP (IR2101) and 8-lead SOIC (IR2101S) packages, both RoHS-compliant and lead-free (PbF). The device uses a standard dual-in-line or small-outline footprint with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN | High-side logic input | In-phase control signal for HO output; accepts 3.3V/5V/15V CMOS/LSTTL levels |
| LIN | Low-side logic input | In-phase control signal for LO output; independent of HIN for asymmetric PWM |
| HO | High-side gate drive output | Floating N-channel driver output referenced to VS; drives gate of high-side MOSFET/IGBT |
| LO | Low-side gate drive output | Ground-referenced N-channel driver output; sinks/source up to 270 mA |
| VB | High-side floating supply | Bootstrap capacitor connection point; supplies high-side driver stage referenced to VS |
| VS | High-side floating return | Reference node for high-side channel; swings from −5 V to +600 V relative to COM |
| VCC | Low-side and logic supply | Fixed 10–20 V rail powering low-side driver, logic, and level-shift circuitry |
| COM | Power ground reference | Common return for LO, logic inputs, and VCC; isolated from VS by internal level shift |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with dV/dt immunity | Rated for 50 V/ns transient tolerance on VS node - suppresses false triggering in noisy high-dV/dt environments |
| Matched propagation delays | ≤50 ns difference between HO and LO turn-on/turn-off - critical for minimizing dead-time uncertainty |
| Independent high/low side outputs | No internal cross-conduction path - allows asymmetric PWM, three-state control, and external dead-time insertion |
| Undervoltage lockout (UVLO) | Separate UVLO on VCC (7.4–9.8 V window) and VB (threshold not specified but functional down to 10 V) - ensures safe power-up/power-down sequencing |
| Logic-level compatibility | Valid operation with 3.3 V logic inputs even at full temperature range (−40 °C to +125 °C) - eliminates need for external translators |
Applications
| Motor Drive Half-Bridge | Induction Heating Inverter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2104PBF | Integrated bootstrap diode and dead-time generator; single-input (IN) with internal logic; no separate HIN/LIN pins | Designed for simpler synchronous buck or half-bridge where automatic dead-time insertion is preferred | Select when reduced external component count and built-in timing control outweigh need for independent HIN/LIN control |
| IRS21844PbF | Higher drive current (260 mA/650 mA), faster propagation (60 ns/30 ns), and enhanced noise immunity; requires external bootstrap diode | Targeted at high-frequency (>500 kHz), high-power industrial inverters demanding tighter timing margins | Select when system requires >200 kHz switching, lower gate charge drive latency, or higher peak current capability |
Compared with IR2101PBF, IR2104PBF simplifies layout with integrated dead time but sacrifices independent channel control, while IRS21844PbF delivers superior speed and drive strength at the cost of increased external component dependency and higher quiescent current.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IR2101PBF is rated for 50 V/ns dV/dt on the VS node under all operating conditions. This specification ensures reliable operation in high-noise environments such as motor drives and resonant converters where rapid bus voltage transients occur. Exceeding this rate may cause false high-side turn-on due to capacitive coupling into the level-shifter circuit.
Can IR2101PBF drive SiC MOSFETs?
Yes - the IR2101PBF can drive SiC MOSFETs provided gate resistance and layout minimize ringing, and the 10–20 V VCC supply aligns with typical SiC gate requirements (e.g., 15–18 V). Its 130 mA/270 mA peak output current supports gate charges up to ~30 nC at 100 ns switching speeds, but external gate resistors must be selected to limit di/dt-induced overshoot.
Is there an internal bootstrap diode in IR2101PBF?
No - the IR2101PBF does not integrate a bootstrap diode. An external fast-recovery or Schottky diode must be placed between VCC and VB to charge the bootstrap capacitor during low-side conduction. This design allows flexibility in diode selection for optimized recovery time and leakage performance.
How does IR2101PBF differ from IR2102PBF?
The IR2101PBF features in-phase logic inputs (HIN→HO, LIN→LO), whereas IR2102PBF provides out-of-phase inputs (HIN→HO, LIN→!LO). This makes IR2101 ideal for independent PWM control of both sides, while IR2102 suits complementary drive schemes where one input controls both outputs inversely - critical for avoiding shoot-through in basic half-bridge implementations.
