By Lzchips
The IR2101STRPBF is a high-voltage, high-speed half-bridge gate driver IC developed by Infineon Technologies, designed specifically for controlling power MOSFETs and IGBTs. Known for its reliability, low power consumption, and excellent noise immunity, this device is widely used in industrial control, power electronics, and automotive applications. Below is a detailed analysis of its core features and applications.
1. Overview
The IR2101STRPBF is a dual-channel, independent half-bridge gate driver capable of controlling high-side and low-side power switches. It utilizes HVIC (High Voltage Integrated Circuit) technology and latch-immune CMOS processes, enabling it to withstand floating voltages of up to 600V and providing robust immunity to negative transient voltages. The logic input is compatible with 3.3V, 5V, and 15V levels, making it suitable for a wide range of control signal sources.
Key Advantages:
-
High Voltage Support: Maximum operating voltage of 600V, with a driver supply range of 10V to 20V. -
High-Speed Response: Typical rise/fall times of 100ns and 50ns, reducing switching losses. -
Matched Propagation Delays: High-side and low-side channels feature matched delays to prevent cross-conduction. -
Strong Drive Capability: Peak output currents of 360mA (sink) and 210mA (source), enabling fast charging and discharging of power device gate capacitances.

3. Pin Functions and Connection
The IR2101STRPBF is available in an 8-pin SOIC package, with the following pin functions:
-
HO (High-Side Output): Connects to the gate of the high-side MOSFET/IGBT. -
LO (Low-Side Output): Connects to the gate of the low-side MOSFET/IGBT. -
VS (High-Side Floating Supply): Floating supply input for the high-side driver. -
VB (Bootstrap Supply): Provides floating supply to the high-side driver via a bootstrap capacitor. -
VCC (Logic Supply): Power supply for the logic circuit (recommended 10V~20V). -
IN (Logic Input): Receives PWM or control signals (non-inverting input). -
SD (Shutdown Protection): Grounded or configured with a resistor for shutdown functionality. -
COM (Common Ground): Reference ground for the low-side driver and logic circuit.
Typical Connection Diagram:
-
The high-side driver requires a bootstrap capacitor (connected between VB and VS) for floating supply. -
Logic signal inputs must match the voltage levels (e.g., 3.3V/5V) to ensure reliable triggering.
4. Typical Applications
-
Motor Drive Systems: Used in three-phase inverters and servo drives to improve switching frequency and efficiency. -
Power Conversion: Applied in DC-AC inverters, switching power supplies, and power factor correction (PFC) circuits. -
Renewable Energy Systems: Utilized in solar inverters and wind power converters for power switch control. -
Industrial Automation: Integrated into high-precision PLC control systems for high-frequency switching circuits.
5. Usage Considerations
-
Power Supply Stability: Ensure VCC and VB voltages remain within the 10V~20V range to avoid overvoltage or undervoltage damage. -
Signal Integrity: Control signals (IN) must meet logic level requirements and be shielded from high-frequency noise. -
Thermal Management: Optimize PCB layout for high-power applications and consider additional heat dissipation measures if necessary. -
Protection Circuits: Configure overcurrent or overtemperature protection using the SD pin to enhance system reliability.
6. Alternative Models and Compatibility
The IR2101STRPBF is compatible with alternative models such as IR2101SPBF and IR2183SPBF, which can be used in scenarios requiring different packages or slight performance adjustments.
