Single-channel isolated gate driver for IGBTs and MOSFETs
The Infineon 1ED3125MU12FXUMA1 is a single-channel isolated gate driver from the EiceDriver™ family, using magnetic coupling to deliver 3000 Vrms galvanic isolation between the input and output. It is designed to drive IGBTs and power MOSFETs in half-bridge and full-bridge topologies, with a peak output current of 14 A that charges the gate capacitance quickly to minimize switching losses. The 4 A sink and 4 A source capability handles moderate-gate-charge devices up to the 150 °C junction temperature limit, making it suitable for motor drives, industrial inverters, and automotive traction inverters where high ambient temperatures are common.
14 A peak output — what it means for switching speed
The 14 A peak output charges the gate capacitance quickly. Compared to the 2 A 1ED020I12BTXUMA1, this driver reduces turn-on time for a given gate charge.
200 kV/µs CMTI — noise immunity in half-bridge switching cells
Common-mode transient immunity of 200 kV/µs (minimum) prevents output glitches during fast switch-node slewing. The 30 ns typical rise/fall time suits IGBTs.
