Low-power motor-drive modules are surface-mount for compact designs
The modules deliver high conduction and switching efficiency, especially in hard-switching circuits, at frequencies up to 20 kHz. The integrated gate-driver circuitry is engineered to minimize electromagnetic emissions (EMI) by managing switching voltage and current slopes (dV/dt, di/dt). The thermally efficient package enhances reliability and allows heatsink-free design, while 2.7 mm creepage and 2.0 mm clearance ensure safety isolation within the compact dual-inline SMD footprint. The module pin configuration is optimized to simplify circuit-board layout.
Features integrated alongside the gate driver and 500V MOSFET or 600V IGBT/freewheel-diode array include an uncommitted operational amplifier and a comparator that let designers implement advanced current sensing and over-current protection with minimal external components. Smart shutdown with high-speed fault detection, interlocking, and under-voltage lockout are all built-in, and integrated bootstrap diodes simplify powering the module’s gate-control circuitry.
SLLIMM -nano power modules, comprising the STIPNS1M50T-H, STIPNS2M50T-H, STIPNS2M50-H, STGIPNS3H60T-H, and STGIPNS3HD60-H, provide a choice of 1A, 2A, or 3A current rating (at 25°C). All are packaged as NSDIP-26L fully-moulded dual-inline surface-mount devices. Pricing starts at $5 (1000) for the STIPNS1M50T-H.
