IR2153

IR2153 Description

The IR2153 from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed for driving MOSFETs and IGBTs in synchronous applications. Operating within a 10V to 15.6V supply range, it integrates two independent drivers (high-side and low-side) with 600V bootstrap capability, making it suitable for high-voltage switching circuits. The device features an RC input circuit for precise timing control and delivers 80ns rise and 40ns fall times (typical), ensuring efficient switching performance. Although marked as obsolete, it remains relevant in legacy designs due to its robustness and reliability.

IR2153 Features

• High-Side Voltage Support: Up to 600V bootstrap voltage for driving high-voltage MOSFETs/IGBTs.
• Fast Switching: 80ns rise / 40ns fall times minimize switching losses.
• Synchronous Operation: Dual-channel (2 drivers) for half-bridge topologies.
• RC Input Circuit: Enables adjustable dead-time control for flexible timing.
• Wide Supply Range: 10V–15.6V operation ensures compatibility with various power supplies.
• Through-Hole Packaging: 8DIP for easy prototyping and legacy PCB designs.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity for extended shelf life.

IR2153 Applications

The IR2153 is ideal for:

• Switch-Mode Power Supplies (SMPS): High-efficiency power conversion in offline supplies.
• Motor Drives: Precise control in brushless DC (BLDC) and stepper motor systems.
• Electronic Ballasts: Driving fluorescent and HID lamp circuits.
• Inverters: Used in solar inverters and UPS systems for high-voltage switching.
