IR2132

IR2132 Description

The IR2132 from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for driving MOSFETs and IGBTs in half-bridge configurations. This obsolete part, packaged in a 28-pin DIP (Through Hole), operates with a supply voltage range of 10V to 20V and supports bootstrap operation up to 600V, making it suitable for high-side switching applications. It integrates six drivers (three high-side and three low-side) with inverting logic inputs, ensuring robust performance in power electronics systems.

IR2132 Features

• High-Side Voltage Capability: Supports up to 600V bootstrap voltage, enabling high-voltage applications.
• Fast Switching: Typical rise/fall times of 80ns and 35ns, respectively, for efficient high-frequency operation.
• High Current Drive: Peak output current of 250mA (source) and 500mA (sink), ensuring strong gate drive for power switches.
• Wide Logic Compatibility: Input thresholds of 0.8V (VIL) and 2.2V (VIH) for broad microcontroller/controller compatibility.
• Robust Packaging: Through-hole 28DIP for reliable mechanical mounting in industrial environments.
• Integrated Protection: Features undervoltage lockout (UVLO) and cross-conduction prevention for enhanced system safety.

IR2132 Applications

The IR2132 is ideal for:

• Motor Drives: Efficiently controls three-phase inverters in industrial and automotive motor systems.
• Power Supplies: Used in switched-mode power supplies (SMPS) and UPS systems for high-voltage switching.
• Renewable Energy: Suitable for solar inverters and wind turbine converters requiring high-side gate driving.
• Industrial Automation: Drives IGBT/MOSFET bridges in welding equipment and induction heating systems.

Conclusion of IR2132

The IR2132 is a high-performance gate driver offering fast switching, high voltage tolerance, and robust drive capability, making it well-suited for demanding power electronics applications. While now obsolete, its 600V bootstrap support, integrated protection, and multi-driver architecture make it a historically significant solution for motor control, power conversion, and industrial systems. Engineers seeking modern alternatives should consider Infineon’s updated gate driver families while acknowledging the IR2132’s legacy in high-voltage switching.
