IRSM808-204MH Half-Bridge IPM for Small Appliance Motor Drive Applications 20A, 250V Description IRSM808-204MH is a 20A, 250V half-bridge module designed for advanced appliance motor drive applications such as energy efficient fans and pumps. IR s technology offers an extremely compact, high performance half-bridge topology in an isolated package. This advanced IPM offers a combination of IR s low R Trench MOSFET technology and the DS(on) industry benchmark half-bridge high voltage, rugged driver in a small PQFN package. At only 8x9mm and featuring integrated bootstrap functionality, the compact footprint of this surface-mount package makes it suitable for applications that are space-constrained. IRSM808-204MH functions without a heat sink. Features Integrated gate drivers and bootstrap functionality Suitable for sinusoidal modulation applications Low 0.15 R (max, 25C) Trench MOSFET DS(on) Under-voltage lockout for both channels IRSM808-204MH Matched propagation delay for all channels Optimized dV/dt for loss and EMI trade offs 3.3V input logic compatible Active high HIN and active low LIN Motor Power range 80-200W Isolation 1500V min RMS ROHS compliant Internal Electrical Schematic VB IRSM808-204MH V+ VCC HIN Vs Half bridge driver with built LIN in bootstrap DT V- COM Ordering Information Orderable Part Number Package Type Form Quantity IRSM808-204MH PQFN 8x9mm Tray 1300 IRSM808-204MHTR PQFN 8x9mm Tape and Reel 2000 1 www.irf.com 2015 International Rectifier February 12, 2015 IRSM808-204MH Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the module may occur. These are not tested at manufacturing. All voltage parameters are absolute voltages referenced to V unless otherwise SS stated in the table. The thermal resistance rating is measured under board mounted and still air conditions.
