IR2132S

IR2132S Description

The IR2132S from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for half-bridge and three-phase motor drive applications. This 6-channel driver integrates three high-side and three low-side drivers with independent inputs, enabling precise control of power MOSFETs or IGBTs. Operating within a 10V to 20V supply range, it supports bootstrap operation up to 600V, making it suitable for high-voltage industrial and automotive systems. The IR2132S features inverting logic inputs with defined thresholds (VIL = 0.8V, VIH = 2.2V) for robust noise immunity.

IR2132S Features

• High-Speed Switching: Fast rise/fall times (80ns/35ns typ) minimize switching losses, improving efficiency in high-frequency applications.
• High Current Drive: Delivers 250mA (source) / 500mA (sink) peak output current for rapid gate charging/discharging.
• Bootstrap Capability: Supports 600V high-side voltage, eliminating the need for isolated power supplies.
• Robust Protection: Built-in undervoltage lockout (UVLO) and cross-conduction prevention enhance system reliability.
• Surface-Mount Package: Housed in a 28-pin SOIC for compact PCB integration.
• Wide Logic Compatibility: Compatible with 3.3V/5V/15V logic systems, offering design flexibility.

IR2132S Applications

The IR2132S excels in:

• Motor Drives: Ideal for BLDC/PMSM motor control in industrial automation and robotics.
• Power Inverters: Used in solar inverters and UPS systems for efficient high-voltage switching.
• Automotive Systems: Suitable for EV/HEV traction inverters due to its high-voltage tolerance.
• Switched-Mode Power Supplies (SMPS): Enhances efficiency in high-power DC-DC converters.

Conclusion of IR2132S

The IR2132S stands out as a high-performance gate driver for demanding power electronics applications. Its fast switching, high current drive, and bootstrap operation make it a preferred choice for motor control and inverters. While marked obsolete, its robust design and Infineon’s legacy ensure continued relevance in legacy systems or niche high-voltage designs. Engineers should evaluate alternative modern equivalents for new projects while considering the IR2132S for proven, high-reliability solutions.
