IR21834SPBF

Gate Driver Overview

The IR21834SPBF is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by Infineon Technologies. It features a half-bridge topology with two independent drivers in a 14-SOIC package. The device supports supply voltages from 10 V to 20 V and drives N-channel power devices up to 600 V. Key electrical parameters include a peak output current of 2.3 A (sink) and 1.9 A (source), propagation delays of 180 ns (turn-on) and 220 ns (turn-off), and rise/fall times of 40 ns and 20 ns respectively. Operating temperature ranges from -40°C to +125°C.

Gate Driver Feature Summary

• Integrated high-side and low-side reference outputs for floating channel operation
• Proprietary HVIC and latch-proof CMOS technology for robust monolithic structure
• Programmable dead-time control to minimize cross-conduction
• Logic inputs compatible with standard CMOS or LSTTL outputs

Gate Driver Applications

• Motor drive applications
• Power supplies
• Inverter circuits

Gate Driver Procurement Notes

Verify the specific suffix 'SPBF' against the manufacturer's official ordering guide to confirm the SOIC-14 surface-mount package configuration. Ensure that the component meets RoHS compliance requirements as specified in the datasheet. Confirm availability status, as some variants within this family may be marked as not recommended for new designs. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Gate Driver Selection Notes

Select this component when a single-chip solution for driving both high-side and low-side switches is required. It is suitable for applications needing precise dead-time control and high voltage isolation. Consider the 14-pin SOIC footprint for PCB layout constraints. Evaluate the 600V rating against the maximum bus voltage of the target application to ensure adequate safety margins.

Gate Driver Part Context

This part belongs to the IRS2183/IR2183 series of half-bridge gate drivers. It shares functional similarities with the IRS21834STRPBF but differs in packaging and tube quantity specifications. The series is designed for industrial and consumer applications requiring reliable switching of power semiconductors.

Gate Driver Replacement Considerations

The IRS21834STRPBF is a documented alternative with identical functionality but in a tape-and-reel package. Verify pinout compatibility before substitution.
