Drive smarter motor designs with the 75 V STSPIN series
High-power 48 V motor drivers for robotic designs
Revolutionizing motor-drive architectures with high power density and control
Reduce design complexity without compromising flexibility. STSPIN9P1 and STSPIN9P2 help engineers develop compact, high-power 48 V motor-control systems for humanoid and industrial applications. They integrate power MOSFETs with gate-driving and control functions in a single device. With solutions for brushed DC, brushless DC, and stepper motors across a 7 V to 75 V motor-supply range, designers can streamline development, reuse proven designs, and address a broad range of robotic and industrial applications.
One portfolio. Two bridge topologies.
One portfolio. Two bridge topologies.
From compact multi-phase motor systems to bidirectional brushed DC and stepper applications, the STSPIN9P portfolio lets you choose the topology that best fits your needs. Choose STSPIN9P1 half-bridges to scale your power stage with options up to 10 A RMS, or STSPIN9P2 full-bridges for bidirectional motor control up to 6 A RMS. Both families support 7 V to 75 V motor supplies and integrate power MOSFETs in compact packages, helping reduce board space and simplify motor-drive design.

Overcome 48 V system design challenges
| What it means | STSPIN solution | Key benefit |
|---|---|---|---|
| Supply transients in 48 V systems | Regenerative braking and switching can cause motor-bus voltage spikes. Peak voltage depends on operating conditions. | 7 V to 75 V recommended motor-supply range. Check worst-case transients and provide system-level clamping where needed. | Supports 48 V system designs, with transient performance validated at the application level. |
| Thermal dissipation in tight spaces | High currents in compact robotic joints lead to overheating and EMI issues. | Low RDS(on) and adjustable slew rate help manage conduction losses and tune switching behavior. | Supports compact power-stage designs. Thermal performance depends on the complete application and its operating conditions. |
| Complex current sensing circuitry | External op-amps add cost, noise, and components to current-feedback loops. | Integrated differential current-sensing amplifier. | Helps simplify the PCB layout and reduce external component count. |
