5.7 kVrms isolation for motor-drive gate drive
The Infineon 1EDS5663HXUMA1 is a single-channel isolated gate driver from the EiceDriver™ series, using magnetic coupling to deliver 5.7 kVrms galvanic isolation between the input and output sides. That isolation rating covers the reinforced insulation requirements for IGBT and SiC MOSFET gate-drive circuits in motor drives, inverters, and industrial power supplies where the control side must be protected from high-voltage DC-link transients. With 4 A source and 8 A sink peak output current, this driver can charge and discharge the gate capacitance of medium-power IGBTs and SiC MOSFETs quickly enough to keep switching losses under control. The 6.5 ns typical rise time and 4.5 ns fall time mean the gate voltage transitions fast, which reduces the time the device spends in the linear region during switching.
CMTI and propagation delay for dead-time margin
Common-mode transient immunity is specified at a minimum of 150 V/ns — this is the key parameter for motor-drive applications where the output-side ground bounces at high dv/dt during IGBT switching. If the CMTI is too low, the isolator can couple the transient across the barrier and corrupt the gate signal, causing shoot-through. At 150 V/ns, this driver keeps the output state stable even on a fast-switching SiC half-bridge. Propagation delay is matched at 44 ns max for both rising and falling edges, with pulse-width distortion typically 18 ns. Tight delay matching simplifies dead-time calculation in the controller firmware — you can budget a fixed dead-time without worrying about the driver adding asymmetric delay that varies with temperature or supply voltage.
The 1EDS5663HXUMA1 comes in a 16-SOIC wide-body package (PG-DSO-16-30) with a 7.50 mm body width, surface-mount for automated assembly. The output-side supply operates from 3.13 V to 3.47 V — a narrow window that requires a regulated rail, typically from a DC-DC converter or an LDO dedicated to the gate-drive bias.
Regulatory and lifecycle status
The 1EDS5663HXUMA1 carries approvals from CQC, CSA, UL, and VDE — these cover the safety isolation certification needed for equipment sold into North American, European, and Chinese markets. It is also ROHS3 compliant, with no restricted substances under the latest EU directive.
