This document is the specification of RAiO RA8825 128x33 LCD driver controller, which mainly introduces the product's features, functions, interface definition, electrical characteristics, etc.

The MAST5-4C-U12 IGBT driver board is a 4-channel IGBT driver that uses AST965 and has a drive current of 5A per channel. It has 4 mutually isolated DC-DCs, with an isolation voltage of 2500VAC. It uses current source drive mode to reduce Miller effect time and switching losses under the same EMI conditions. It has short-circuit protection using the VCE detection method. It has undervoltage protection. It has IGBT gate TVS protection devices. It has power and pulse indicators. It has a concentrated flat-line signal interface that supports multiple input levels. Externally, it only needs to input 1 power supply of 12VDC (9-18V) or 24VDC (18-32V).
