Gate Driver datasheet and documents for IR2181STRPBF

IR2181STRPBF

Gate Driver Overview

The IR2181STRPBF is a high-voltage, high-speed power MOSFET and IGBT driver featuring independent high-side and low-side referenced output channels. It supports supply voltages from 10 V to 20 V with peak output currents of 1.8 A source and sink. The device operates up to 600 V using bootstrap configuration and includes undervoltage lockout for both channels. Key timing parameters include a maximum turn-on delay of 180 ns, turn-off delay of 220 ns, rise time of 60 ns, and fall time of 35 ns. It accepts CMOS or TTL logic inputs and functions within an operating temperature range of -40°C to +125°C.

Gate Driver Feature Summary

Independent high-side and low-side output channels designed for half-bridge configurations
Floating high-side channel capability supporting bootstrap operation up to 600 V
Tolerance to negative transient voltage and dV/dt immunity for robust switching
Undervoltage lockout protection integrated for both driver channels

Gate Driver Applications

High-frequency motor drive systems
Power factor correction (PFC) circuits
DC-to-AC inverter topologies
Resonant converter designs

Gate Driver Procurement Notes

Verify the specific suffix 'STRPBF' to confirm the SOIC-8 surface-mount tape-and-reel packaging format. Confirm component status as Not Recommended for New Designs (NRND) to assess long-term availability and lifecycle implications before finalizing procurement plans.

Gate Driver Selection Notes

Select this component when independent high and low side driving is required for IGBTs or MOSFETs. Ensure the application demands a floating high-side voltage capability up to 600 V. Verify that the input logic levels are compatible with standard CMOS or TTL standards and that the package size fits the PCB layout constraints.

Gate Driver Part Context

This part belongs to the IR2181 family of gate drivers manufactured by Infineon Technologies. It is functionally related to variants such as IR2181SPBF and IR2181S, differing primarily in packaging and reel specifications while maintaining identical electrical performance characteristics for power switching applications.
