IR2131

Gate Driver Overview

The IR2131 is a high-voltage, high-speed power MOSFET and IGBT driver featuring three independent high-side and low-side referenced output channels. It supports supply voltages from 10 V to 20 V with peak output currents of 250 mA source and 500 mA sink. The device operates within a temperature range of -40°C to +150°C TJ. Key timing parameters include rise times of 80 ns and fall times of 40 ns, with maximum on/off delays of 1300 ns and 600 ns respectively. Logic inputs are compatible with CMOS and TTL standards at 0.8 V and 2.2 V thresholds.

Gate Driver Feature Summary

• Provides three independent half-bridge driver channels for high-side and low-side switching applications.
• Features proprietary bootstrap diode integration for simplified high-side drive circuitry.
• Supports direct interface with standard logic families including CMOS and TTL inputs.

Gate Driver Applications

• Three-phase motor control systems
• Switch-mode power supplies (SMPS)
• Inverter circuits for AC drives

Gate Driver Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Check RoHS compliance status as variants may differ. Confirm package type matches design requirements. Review datasheet revisions for parameter updates. Ensure storage conditions meet moisture sensitivity level specifications before assembly.

Gate Driver Selection Notes

Select the IR2131 for applications requiring isolated gate driving of multiple power switches. Consider thermal management due to power dissipation limits. Evaluate PCB layout for high dv/dt noise immunity. Match input logic levels to controller outputs. Verify voltage ratings exceed peak bus voltages in the target application.

Gate Driver Part Context

The IR2131 belongs to the IR213x family of gate drivers designed for industrial power conversion. It replaces earlier generations with improved speed and integration. Variants include SOIC and PLCC packages. The device is widely used in legacy motor drive designs. Newer alternatives may offer higher current capabilities.

Gate Driver Replacement Considerations

IR2131S and IR2131JPBF are package-specific variants of the same core function. Cross-reference pinouts when substituting between SOIC and PLCC packages. Verify electrical parameters match original design requirements. Check availability as some variants may be discontinued.
