The IR21362STR is a high-voltage, high-speed, three-phase gate driver from Infineon Technologies. It is designed to drive three N-channel MOSFETs or IGBTs in a half-bridge configuration, making it ideal for applications such as motor control, power tools, and uninterruptible power supplies (UPS).

Applications:

• Three-Phase Motor Control
• Power Inverters
• Brushless DC (BLDC) Motor Drives
• Uninterruptible Power Supplies (UPS)
• Power Tools

Features:

• Three-Phase Gate Driver
• High-Side and Low-Side Drivers for Each Phase
• Floating Channel Designed for Bootstrap Operation
• High-Voltage Capability
• High-Speed Operation
• Under-Voltage Lockout (UVLO)
• Shoot-Through Protection
• SO-28 Package
• Lead-Free
• RoHS Compliant

Benefits:

• Simplified Three-Phase Drive: Integrates all necessary gate drivers for a three-phase half-bridge, reducing component count and board space.
• Improved Efficiency: Enables efficient driving of MOSFETs or IGBTs in high-frequency applications.
• Robust Protection: UVLO and shoot-through protection prevent damage to the driven devices during abnormal operating conditions.
• Fast Switching: High-speed operation reduces switching losses.
• Reliable Performance: Designed for demanding applications, ensuring stable and consistent operation.

Specifications:

The IR21362STR features a high-side floating channel voltage of up to 600V. It requires a gate drive supply voltage typically between 10V and 20V. The built-in shoot-through protection prevents simultaneous conduction of the high-side and low-side MOSFETs/IGBTs in each phase leg. The UVLO function protects the power switches from operating with insufficient gate drive voltage. It is supplied in a SO-28 package.

Proper PCB layout, including adequate decoupling and minimizing parasitic inductance, is essential for reliable operation of the IR21362STR. Refer to the datasheet for detailed specifications, application notes, and layout recommendations.
