EiceDRIVER™ 2L-SRC Compact and EiceDRIVER™ SRC Enhanced family

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 = 5.7 kV (rms) and VDE 0884-11 (reinforced isolation) with VIORM = 1797 V (peak).

EiceDRIVER™ SRC Enhanced family (1EDS-SRC) marks the high end of slew-rate control gate driver families implementing multi-level slew-rate control.

EiceDRIVER™ 2L-SRC Compact family (1ED32xx)

EiceDRIVER™ 2L-SRC Compact family (1ED32xx) optimizes the gate driver circuit to balance the reduction of dV and dt and electromagnetic interference (EMI) during start-up and light-load operation and minimizes switching losses during high-load operation. The slew rate can be adapted on-the-fly during operation based on gate resistor changes, enabling the system output power to be optimized without changing the BOM and without compromising the EMI behavior.

Additional information about the EiceDRIVER™ with slew-rate control

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. Additionally, 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. Additionally, it is a perfect match for applications including solar systems, uninterruptible power supplies, and EV charging.

Key benefits

The key benefits include the two-level slew-rate control feature (2L-SRC), 2300 V functional offset voltage capable for selected applications,  galvanically isolated coreless transformer gate driver, 18 A typical sinking and sourcing peak output current, 40 V absolute maximum output supply voltage, short-circuit clamping and active shutdown, high common-mode transient immunity (CMTI) >200 kV/μs, and DSO-8 300 mil wide-body package with large creepage distance (>8 mm), max. 110 ns propagation delay with typ. 35 ns input filter, and optimized for use with 650 V, 1200 V, 1700 V, and 2300 V IGBTs, and Si and SiC MOSFETs.

Key features

EiceDRIVER™ with slew-rate control incorporate important key features, e.g., 2L-SRC that optimizes gate resistors for EMI measurements and for normal operation in motor control and drive application, compared with the conventional solution, the integrated filters that reduce the need of external filters, 1 ns propagation delay matching between outputs, IEC 60747-17/VDE 0884-11 with VIORM = 1767 V (peak, reinforced), high isolation capability that can be used in 1700 V drive  inverter applications, tight propagation delay matching between outputs which enables superior slew-rate control functionality over discrete solutions, precise threshold and timings, combined with UL and VDE-11 certification that enable superior application safety, and tight IC-to-IC turn-on propagation delay matching (15 ns max.).
