Three half-bridges, one supply rail — BLDC drive simplified
The Texas Instruments DRV8313PWP is a fully integrated motor driver that packs control logic and three power MOSFET half-bridges into a single 28-HTSSOP package. It is designed specifically for brushless DC (BLDC) motors, handling the commutation sequencing internally when driven through the parallel interface. The single supply rail accepts 8V to 60V, covering 12V, 24V, and 48V industrial bus voltages without needing an extra regulator for the gate drive.
Wide supply and temperature headroom
The 8V to 60V supply range means this part can run directly off a rectified 48V DC bus or a 12V automotive battery line. The operating junction temperature range of -40°C to 150°C allows placement near the motor or inside a sealed enclosure without forced cooling. For a procurement planner, that temperature grade also signals suitability for under-hood or outdoor industrial environments where ambient heat cycles are common.
Active lifecycle, no obsolescence risk
The DRV8313PWP carries an Active product status and is ROHS3 compliant. There is no NRND or last-time-buy notice on this part, so it can be specified into new designs with confidence.
Package and mounting — 28-HTSSOP with PowerPAD
The device is supplied in a 28-lead PowerTSSOP (0.173" body width, 4.40 mm pitch) with an exposed thermal pad (HTSSOP). It is a surface-mount part shipped in Tube form. The PowerPAD must be soldered to a copper plane on the PCB for thermal dissipation — a standard requirement for any driver handling multiple amps.
