SECO-NCD57000-GEVB NCD57000 mini Evaluation Board User s Manual Purpose This document describes the use and applications for the www.onsemi.com NCD57000 gate driver mini board. The board is designed on a two layer PCB and includes the NCD57000 driver and all the necessary EVAL BOARD USERS MANUAL drive circuitry. The board also includes ability to solder any MOSFET or SiC MOSFET in a TO247 high voltage package and compatibility with SECOGDBBGEVB baseboard for outofthebox evaluation. The board does not include a power stage and is generic from the point of view that it is not optimized to any particular topology. It can be used in any lowside or highside power switching application. For bridge configurations two or more of these boards can be configured in a totem pole type drive configuration. The boards can be considered as an isolator+driver+TO247 discrete module. NCD57000 Description Figure 1. SECONCD57000GEVB NCD57000 is a highcurrent single channel IGBT driver with internal galvanic isolation, designed for high system efficiency and reliability in high power applications. Its features include complementary inputs, open drain FAULT and Ready outputs, active Miller clamp, accurate UVLOs, DESAT protection, soft turnoff at DESAT, and separate high and low (OUTH and OUTL) driver outputs for system design convenience. NCD57000 accommodates both 5 V and 3.3 V signals on the input side and wide bias voltage range on the Figure 2. Board Plugged into driver side including negative voltage capability. NCD57000 provides SECOGDBBEVB > 5 kVrms (UL1577 rating) galvanic isolation and > 1200 Viorm (working voltage) capabilities. NCD57000 is available in the Features widebody SOIC16 package with guaranteed 8 mm creepage distance between input and output to fulfill reinforced safety Galvanic Isolated Gate Driver Circuit 5 kV insulation requirements.
