Product details
Overview
IR2107 from Infineon Technologies is a high-voltage, high-speed MOSFET and IGBT driver for half-bridge configurations, featuring 600 V high-side floating capability, 1.4 A typical sink/source current, and integrated bootstrap diode. It operates with 10–20 V VDD, supports 500 ns propagation delay (max), and is used in brushless DC motor controllers and SMPS half-bridge stages.
For engineers reviewing the IR2107 datasheet, IR2107 pinout, IR2107 application, or IR2107 equivalent, key selection considerations include bootstrap-based high-side gate drive compatibility, undervoltage lockout thresholds (VB UVLO = 9.1 V, VDD UVLO = 9.8 V), thermal shutdown behavior, and minimum dead-time requirements for shoot-through prevention.
Technical Context
The IR2107 integrates independent high-side and low-side drivers with matched propagation delays (tPHL/tPLH ≤ 500 ns) and non-overlapping logic to prevent cross-conduction. Its floating channel supports operation up to +600 V referenced to VS, with level-shifted input signals compatible with standard CMOS/TTL logic.
It features separate HO and LO outputs with dedicated source/sink paths, internal bootstrap diode for gate charge replenishment, and dual undervoltage lockout (UVLO) on both VB and VDD rails to ensure safe turn-off during supply brownout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBS Max | 600 V - Enables direct high-side switching in 400 V DC bus applications without external level shifters |
| IO(source/sink) | 1.4 A / 1.8 A - Sufficient to drive 100 nC gate charge MOSFETs at ≥100 kHz switching frequency |
| tPD (max) | 500 ns - Supports precise timing control in BLDC commutation and resonant LLC topologies |
| VDD UVLO | 9.8 V (on), 8.8 V (off) - Prevents erratic output during startup or brownout in 12 V supply systems |
| VB UVLO | 9.1 V (on), 8.1 V (off) - Ensures high-side MOSFET remains off if bootstrap voltage collapses below safe gate threshold |
| Operating Temp | −40°C to +125°C - Qualified for industrial motor drives and outdoor power conversion environments |
Pinout & Package
IR2107 is housed in an 8-pin DIP (dual in-line package) with 0.3-inch lead spacing and through-hole mounting. The package provides creepage/clearance suitable for 600 V isolation requirements in AC-DC and motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Low-side supply rail | Provides logic and low-side driver power; must be decoupled with ≥1 μF ceramic capacitor |
| COM | Low-side return path | Common ground reference for logic inputs and LO output; must be star-connected to minimize noise coupling |
| HIN | High-side input | TTL/CMOS-compatible control signal for HO output; internally pulled down when floating |
| LIN | Low-side input | TTL/CMOS-compatible control signal for LO output; internally pulled down when floating |
| HO | High-side gate driver output | Drives high-side MOSFET gate relative to floating VS node; requires external gate resistor for dV/dt control |
| VS | Floating source reference | Connects to switch node between high- and low-side devices; defines return for HO output |
| VB | Bootstrap supply input | Accepts charge from bootstrap capacitor; internal diode enables self-biasing during low-side conduction |
| LO | Low-side gate driver output | Drives low-side MOSFET gate relative to COM; capable of 1.8 A sink current for fast turn-off |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Eliminates external diode, reducing BOM count and PCB footprint in half-bridge gate driver designs |
| Dual UVLO protection | Independent monitoring of VB and VDD ensures fail-safe shutdown even if bootstrap capacitor fails to recharge |
| Matched propagation delays | Ensures symmetrical timing between HO and LO edges, critical for minimizing dead-time uncertainty in PWM control |
| Floating high-side driver | Supports operation with VS swinging from −5 V to +600 V, enabling use in high-voltage bridge configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2106 | Lacks integrated bootstrap diode; requires external diode and larger bootstrap capacitor | Suitable only where board space allows extra components and layout complexity is acceptable | Choose IR2106 only if cost sensitivity outweighs BOM simplification and layout reliability needs |
| IRS2107 | Same pinout and specs but offered by Infineon's legacy product line with identical electrical behavior | No functional difference; IRS2107 is rebranded IR2107 for specific distribution channels | Select IRS2107 only when sourcing from authorized distributors listing that part number explicitly |
Compared with IR2106, IR2107 reduces design risk via integrated bootstrap diode and tighter propagation delay matching; compared with IRS2107, it is functionally identical but tracked separately in Infineon's product lifecycle management.

FAQ
What is the minimum recommended bootstrap capacitor value for IR2107?
A 0.1 μF ceramic capacitor is the minimum recommended value for typical 100 kHz operation with 100 nC gate charge loads. Larger values (≥0.22 μF) improve reliability under high-duty-cycle or high-temperature conditions by maintaining sufficient VB margin above the 9.1 V UVLO threshold.
Does IR2107 support 3.3 V logic inputs?
Yes - IR2107 accepts TTL/CMOS logic levels with VIL ≤ 0.8 V and VIH ≥ 2.0 V, making it compatible with 3.3 V microcontrollers without level-shifting. Input thresholds are independent of VDD within its 10–20 V operating range.
Can IR2107 drive SiC MOSFETs directly?
IR2107 can drive low-to-mid capacitance SiC MOSFETs (Qg ≤ 80 nC) at ≤50 kHz, but lacks active Miller clamp or negative turn-off features. For high-frequency or high-dV/dt SiC applications, a dedicated SiC driver with enhanced noise immunity is recommended.
Is thermal shutdown implemented in IR2107?
No - IR2107 does not include internal thermal shutdown. Safe operation relies on proper PCB copper area (≥1 cm² per power pad), ambient temperature control, and adherence to SOA limits defined in the datasheet's power dissipation curves.
