2ED2181S06FXUMA1

Gate Driver Overview

The Infineon Technologies 2ED2181S06FXUMA1 is a high-voltage, high-speed gate driver IC designed for driving power MOSFETs and IGBTs. It features independent high-side and low-side output channels with a maximum bootstrap voltage of 650 V. The device provides peak output currents of 2.5 A for both sourcing and sinking. It operates within a supply voltage range of 10 V to 20 V and supports CMOS and LSTTL logic inputs. Typical rise and fall times are 15 ns, with a maximum propagation delay of 300 ns. The component functions in an inverting configuration and includes a shutdown feature. It is housed in a PG-DSO-8-53 package and operates between -40°C and +125°C.

Gate Driver Feature Summary

• Independent high-side and low-side referenced output channels for half-bridge applications
• Integrated bootstrap diode for simplified high-side drive circuitry
• High peak output current capability of 2.5 A for fast switching
• Shutdown pin functionality for safe system control

Gate Driver Applications

• Power MOSFET and IGBT gate driving in industrial motor drives
• Inverter circuits for AC/DC and DC/AC conversion systems
• Switched-mode power supplies (SMPS) requiring isolated or floating gate drive

Gate Driver Procurement Notes

Verify the complete ordering part number matches the required suffixes for packaging and temperature grade. Confirm that the specific variant aligns with the intended application voltage and logic interface requirements. Check RoHS compliance status and moisture sensitivity level handling instructions during assembly. Ensure the supplier provides valid traceability documentation for automotive or industrial quality standards if applicable.

Gate Driver Selection Notes

Select this component when a 650V rating is required for the high-side channel. Choose based on the need for 2.5A peak current to drive larger power devices. Consider the inverting logic configuration and DSO-8 package constraints. Evaluate the 15ns switching speed against EMI requirements. Compare against lower current variants if load demands are reduced.

Gate Driver Part Context

This part belongs to the 2ED2181 family of high-voltage gate drivers from Infineon. It is specifically engineered for half-bridge topologies using MOSFETs or IGBTs. The series offers integrated bootstrap diodes and robust isolation characteristics. It serves as a critical interface between low-voltage control logic and high-power switching elements in energy conversion systems.

Gate Driver Replacement Considerations

Direct substitutes include other 2ED2181 variants with different packaging or suffix codes, such as 2ED2181S06F. Cross-family replacements require matching the 650V rating, 2.5A output current, and DSO-8 footprint. Verify pin compatibility and logical inversion behavior before substitution.
