EiceDRIVER™ with Slew-Rate Control
Slew-rate control enabled, up to 5.7 kV (rms) galvanically isolated single-channel gate driver families with reinforced isolation (VDE 0884-11)
Slew-rate control enables on-the-fly gate resistor adjustments during operation, thus simultaneously improving system efficiency and electromagnetic interference (EMI).
The EiceDRIVER™ 2L-SRC Compact family (1ED32xx) implements two-level slew-rate control (2L-SRC) offering the control of two independent gate resistors. It is a single-channel isolated gate driver family with up to 18 A output current and wide output supply voltage range. The family is certified according to UL 1577 with VISO = 5.7kV (rms) and VDE 0884-11 (reinforced isolation) with VIORM = 1797 V (peak).
The EiceDRIVER™ SRC Enhanced family (1EDS-SRC) marks the high-end of slew-rate control gate driver families, implementing multi-level slew-rate control.
The EiceDRIVER™ 2L-SRC Compact family (1ED32xx) optimizes the gate driver circuit to balance the reduction of dv/dt and electromagnetic interference (EMI) during start-up and light-load operation, as well as minimizes switching losses during high-load operation. The slew rate can be adapted on-the-fly during operation based on gate resistor changes, enabling system output power to be optimized without changing the BOM and without compromising EMI behavior.
The gate driver family provides driving currents of 10 and 18 A. It also includes a Miller clamp that is highly recommended for power switches that use 0 V turn-off to avoid parasitic turn-on. With voltage ratings up to 2300 V, it supports power switches far beyond 1200 V blocking voltage. Furthermore, UL 1577 and VDE 0884-11 (reinforced isolation) certificates ensure superior application safety and guarantee long operating life.
With high voltage and high safety capabilities, the product family is suitable for applications with demanding isolation requirements, such as 1700 V industrial drives. Furthermore, it is a perfect match for applications including solar systems, uninterruptible power supplies and EV charging.
