BM60052FV-C Evaluation Board
(For 300 A/1200 V Full-SiC Power Module
Drive)
BM60052FV-EVK-001
1-1. Overview
BM60052FV-EVK-001 (BM60052FV-C Evaluation Board) is an evaluation board whose shape allows direct mounting onto
the ROHM’s 2ch 300 A/1200 V class full-SiC power module, BSM300D12P2E001.
This is a single unit, comprising the SiC-MOSFET gate drive circuit along with the gate driver IC, the BM60052FV-C
integrating insulation element, and an insulated DC-DC converter, supplying gate voltage.
The constant is set to the value suitable for driving BSM300D12P2E001.
Integrated functions include SiC-MOSFET’s DESAT detection function, soft turn-off function at DESAT detection, DESAT
detection FLT signal output function, gate bias voltage reduction detection/gate state monitoring RDY signal output function,
and mirror clamp function.
This evaluation board is intended to be used with BM60052FV-C to drive the full-SiC power module for evaluation. However,
it is not designed for mass-production use.
