　　IRSM836-044MA is a 4A, 250V Integrated Power Module (IPM) designed for advanced appliance motor drive applications such as energy efficient fans and pumps. IR’s technology offers an extremely compact, high performance AC motor-driver in an isolated package. This advanced IPM offers a combination of IR’s low RDS(on) Trench MOSFET technology and the industry benchmark 3-phase high voltage, rugged driver in a small PQFN package. At only 12x12mm and featuring integrated bootstrap functionality, the compact footprint of this surface-mount package makes it suitable for applications that are space-constrained. Integrated over-current protection, fault reporting and under-voltage lockout functions deliver a high level of protection and fail-safe operation. IRSM836-044MA functions without a heat sink.

　　IRSM836-044MA主要特性:

　　 Integrated gate drivers and bootstrap functionality

　　 Open-source for leg-shunt current sensing

　　 Protection shutdown pin
