IR2153

Gate Driver Overview

The IR2153 is a self-oscillating half-bridge gate driver IC designed for motor control applications. It features an integrated 600V bootstrap FET and a 15.6V zener clamp on the Vcc supply. The device supports micropower startup and provides tight initial deadtime control. It operates with a supply voltage range of 10V to 15.6V, with UVLO thresholds at 9V (On) and 8V (Off). The output stage delivers a peak current of 400mA. The component utilizes junction isolation for level shifting and is housed in a PDIP-8 package.

Gate Driver Feature Summary

• Integrated 600V half-bridge topology with built-in bootstrap functionality
• Self-oscillating operation with programmable frequency via external components
• Micropower startup capability for efficient power management
• Tight initial deadtime control to prevent shoot-through

Gate Driver Applications

• Brushed DC motor control systems
• Power tool drive circuits
• Solenoid actuation drivers
• General purpose half-bridge switching applications

Gate Driver Procurement Notes

Verify that the IR2153 is marked as Not Recommended for New Designs (NRND). Confirm if the specific orderable part number includes the PBF suffix for lead-free compliance. Check for availability of the recommended replacement IRS2153D, which offers updated specifications and industrial quality ratings. Ensure supply chain sources are authorized to avoid counterfeit components.

Gate Driver Selection Notes

Select the IR2153 for legacy designs requiring self-oscillating half-bridge driving without external PWM controllers. Consider the IRS2153D for new projects due to its improved UVLO margins and industrial qualification. Evaluate the 400mA output current against load requirements. Verify that the 600V rating meets the system's voltage stress needs. Assess thermal performance within the specified operating temperature range.

Gate Driver Part Context

The IR2153 belongs to the third-generation IR215x family of high-voltage gate drivers from Infineon Technologies. It succeeded earlier second-generation variants like the IR2151. This series is characterized by monolithic integration of bootstrap diodes and FETs, simplifying circuit design for half-bridge configurations in medium-power motor drives.

Gate Driver Replacement Considerations

The IRS2153D is the officially recommended replacement for new designs. It shares similar functionality but features adjusted UVLO thresholds and industrial-grade certification. Verify pin compatibility before substitution.
