Key Features
- Dual full-bridge topology enables simultaneous control of 2 brushed DC motors or 1 bipolar stepper motor from a single IC
- Integrated current sensing and regulation circuitry reduces external component count and simplifies motor torque control
- 24-pin TFQFPN package with exposed thermal slug dissipates heat efficiently, supporting higher continuous motor currents in compact designs
Applications
The STSPIN840 is designed for battery-powered robotics, drones, and handheld tools requiring dual independent brushed DC motor control or bipolar stepper actuation in a small footprint. Its integrated current regulation and thermal slug make it equally applicable in industrial conveyor actuators and 3D printer carriage drives, where sustained motor currents and thermal headroom are critical within a space-constrained PCB layout.

Frequently Asked Questions
How many motor axes can the STSPIN840 control simultaneously, and what motor types does it support?
The STSPIN840 contains 2 independent full H-bridge channels, allowing simultaneous drive of 2 brushed DC motors or configuration as a single bipolar stepper motor driver. Each H-bridge independently handles direction and PWM speed control, enabling coordinated dual-axis motion in robotic platforms without additional driver ICs.
What package does the STSPIN840 use, and why does its thermal design matter for continuous motor drive?
The STSPIN840 is housed in a 24-pin TFQFPN package measuring approximately 4 mm x 4 mm with an exposed heat-sink slug on the bottom. The slug bonds directly to a PCB copper pour, reducing junction-to-board thermal resistance and allowing higher continuous motor currents compared to leaded packages of similar pin count.
Does the STSPIN840 include current sensing for motor torque control, and what benefit does this provide?
Yes, the STSPIN840 integrates current sensing and regulation circuitry internally. This allows the controller to limit peak winding current to a set reference level, protecting the motor from overcurrent during stall or sudden load increases, and reducing the need for external shunt resistors and op-amp sensing circuits.
For a compact 2-wheel differential-drive robot, what advantages does using a single STSPIN840 offer over two separate single H-bridge drivers?
Using one STSPIN840 instead of two separate drivers reduces BOM count from 2 packages to 1, saving approximately 16 mm² to 25 mm² of board area and cutting per-unit cost. Synchronous control timing is also simpler because both bridges share a common enable and logic supply, eliminating inter-IC skew in direction changes.
