Half-bridge driver for AC motor drives
The Infineon IRSM807-105MHTR is a half-bridge driver IC in the µIPM™ series, rated for 10 A continuous output per channel and a maximum load voltage of 400 V. It integrates the gate drive and power MOSFETs in a single 31-PowerVQFN package, targeting AC motor drives in appliance and light industrial applications.
10 A output, 400 V bus, 580 mOhm Rds(on)
With a typical Rds(on) of 580 mOhm, the conduction loss at 10 A is under 6 W per channel — the 31-PQFN (8x9 mm) package relies on the PCB copper pour for thermal dissipation, so the board layout directly governs the usable duty cycle. The supply range of 13.5 V to 16.5 V powers the internal gate drive and bootstrap circuit, which generates the high-side floating supply from the low-side rail — no isolated DC-DC needed for the high-side gate. Integrated UVLO fault protection holds the outputs off until the supply voltage rises above the threshold, preventing the MOSFETs from operating in the linear region during power-up or brownout. The UMOS technology is a trench-based power MOSFET process that keeps the gate charge low enough for direct logic-level interface — no external level shifter required.
