48-HTSSOP brushed DC driver with 6 A continuous output
The Toshiba TB67H400AFNG,EL is a fully integrated brushed DC motor driver that packs the control logic and Power MOSFET output stage into a 48-HTSSOP exposed-pad package. The four half-bridge outputs let you drive a single brushed DC motor in both directions or configure the bridges for other DC-load topologies. The Parallel and PWM interface gives the host controller direct control over each bridge leg — no serial protocol overhead, just logic-level signals and a PWM input for speed or torque regulation.
Package, thermal pad, and rework considerations
The 0.50 mm pin pitch on the HTSSOP body means a hot-air rework station with a fine nozzle is the right tool for removal. Pre-bake the part per JEDEC MSL level if it has been exposed to ambient humidity — the exposed pad wicks moisture into the die attach, and a rapid heat cycle can pop the package. Tin the pad, flux it, and let the surface tension self-align the part on reflow.
