EVAL-1ED3251MC12H
Evaluation board for EiceDRIVER™ 2L-SRC Compact with two-level slew-rate control
EVAL-1ED3251MC12H is in half-bridge configuration with two-level slew-rate control (2L-SRC) enabled gate driver ICs (1ED3251MC12H) and active Miller clamp. This board enables the evaluation of the slew-rate control switching scheme. The switch type can be freely chosen. TRENCHSTOP™ IGBT7 IKQ75N120CS7 is recommended. An additional gate driver IC is used for ultra-fast isolated over-current feedback signal from the high voltage side to the logic control which enables it for use with SiC MOSFETs. This board is best suited for double-pulse testing.
1ED3251MC12H belongs to the EiceDRIVER™ 1ED32xx family (2L-SRC Compact family). 1ED3251MC12H offers two separate outputs with 18 A typical peak output current to control two independent gate resistances for turn-on thus enabling two-level slew-rate control. It implements active Miller clamp to avoid parasitic turn-on. The driver can operate over a wide supply voltage range, either unipolar or bipolar.
