1ED3122MU12HXUMA1

Overview

The 1ED3122MU12HXUMA1 is a single-channel isolated gate driver from the EiceDRIVER family, designed for high-voltage power applications. It features magnetic coupling technology providing 1200 Vrms isolation voltage and a minimum common-mode transient immunity of 200 kV/µs. The device delivers a peak output current of 10 A with source and sink currents of 5.5 A each. It operates within a supply voltage range of 10 V to 35 V and supports switching frequencies up to 100 kHz. Typical rise and fall times are 15 ns, with propagation delays of 50 ns maximum. The component is housed in a PG-DSO-8-66 package and functions across an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrates magnetic coupling technology for robust galvanic isolation and high common-mode transient immunity.
• Provides active Miller clamp functionality to prevent false turn-on events during switching transitions.
• Features independent high-side and low-side drive outputs optimized for half-bridge configurations.

Applications

• Industrial motor drives
• Solar energy systems
• EV chargers

Procurement Notes

Verify the specific suffix 'XUMA1' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the PG-DSO-8-66 footprint matches the target PCB layout dimensions. Ensure the 1200 Vrms isolation rating meets the safety requirements of the intended application environment. Cross-reference the UL certification status if regulatory compliance is mandatory for the final product design.

Selection Notes

Select this component when a single-channel driver with 1200 Vrms isolation is required for SiC or IGBT modules. The 10 A peak current capability suits medium-power applications. Consider the 15 ns switching speed for efficiency optimization. Evaluate the 35 V maximum supply voltage against the available gate drive power rails. Compare against higher voltage variants like the 1ED3122MC12H if 2300 V isolation is necessary.
