SDM05M50DBE/DBS is a 3-phase brushless DC motor driver IC with highly-integrated and high reliability, using for small power motor drive applications such as fan motor, consisting of built-in 6 fast recovery MOSFET and 3 half-bridge HVIC for gate driving. 

SDM05M50DBE/DBS integrates under-voltage protection circuit, providing perfect protection and fail-safe operation. Each phase current of inverter can be monitored separately due to divided negative dc terminals. 

SDM05M50DBE/DBS is designed with good insulation, perfect thermal properties and low EMI. It is compact and suitable for built-in motors or any other applications requiring the compact installation.
