36-WQFN motor driver with integrated power stage
The TB62261FTAG,EL from Toshiba Semiconductor is a fully integrated motor driver combining control logic and a Power MOSFET output stage in a single 36-WQFN (6x6 mm) package with an exposed thermal pad. It drives a bipolar stepper motor in full-, half-, or quarter-step resolution, or a brushed DC motor, through four half-bridge outputs rated 800 mA continuous.
Output stage and motor compatibility
Four half-bridge outputs configured in an H-bridge pair for bipolar stepper control or as dual H-bridges for two brushed DC motors — the parallel interface selects the step mode and direction. Step resolution options of 1, 1/2, and 1/4 let the designer trade torque ripple for microstep smoothness without external indexer logic. Rated for appliance-class applications, the driver operates over a junction temperature range of -20°C to 150°C, covering the thermal envelope of enclosed PCB assemblies in white goods and small pumps.
