Vue d'ensemble

Description

STSPIN840 is STMicroelectronics’ integrated motor-driver IC for brushless DC (BLDC) and stepper motors. It combines a three-phase power stage (six MOSFETs) with control logic in a compact package, enabling direct motor control from a microcontroller.
Key features (typical):
- Programmable current regulation and control of microstepping (and/or sensorless/sensored operation, depending on configuration)
- Protection: overcurrent, overvoltage/undervoltage, overtemperature, and fault reporting
- Simple control interface (STEP/DIR-style inputs or equivalent) with status outputs
- Designed for compact, efficient, low-to-mid power motor drives
Applications:
- Printers, robotics, CNC, automation, and other hobbyist to mid-range motor systems
How to use:
- Choose according to the motor type and power needs, set the current limit, provide the control signals, and monitor fault/status pins. For exact current rating, voltage range, microstep resolution, and package options, see the latest ST datasheet and application notes.

Features

STSPIN840 features (concise):
- 2‑phase bipolar stepper motor driver with integrated power MOSFETs
- PWM current regulation with adjustable peak current for smooth microstepping
- Step/Dir control interface with Enable/Sleep inputs
- Microstepping up to 1/8 (for smooth torque) and low EMI via decay control
- Wide supply range (typical 8–46 V) with undervoltage lockout
- Protections: overcurrent, overtemperature, undervoltage/overvoltage, short to GND or supply
- Diagnostic/status outputs for fault/ready signals
- Compact package with minimal external components (suitable for embedded applications)

Package

STSPIN840 is available in a 28-pin HTSSOP (also called TSSOP-28) package.

Pinout

- Pin count: 28 pins (LQFP-28; also available in other 28‑pin packages such as HTSSOP-28).
- Function: STSPIN840 is a two‑phase bipolar stepper motor driver with integrated power MOSFETs. It provides four motor outputs (OUT1–OUT4) for the bipolar stepper, and controls current via ISENSE and a reference (VREF/RREF). Logic/power pins include VMOT (motor supply), VDD/VCC (logic), and GND. Digital control inputs include STEP and DIR; EN (enable), SLEEP, and RESET. Diagnostics outputs typically include FAULT and STATUS. Package pinout varies by package, but these are the common functional groups.

Manufacturer

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A multinational semiconductor and electronics company (headquartered in Geneva, Switzerland) that designs and manufactures integrated circuits, microcontrollers, MEMS sensors, power management devices, and other semiconductors.

Application

STSPIN840 is a dual H-bridge stepper motor driver for bipolar two‑phase steppers. Typical applications include:
- 3D printers and CNC machines (XY tables)
- Robotics and automation (pan/tilt, linear actuators)
- Packaging, labeling, and pick-and-place equipment
- Office/consumer devices needing precise positioning (printers, scanners, camera focus)
- Medical and lab instruments with positioning stages
- General motion control in automation systems

Equivalent

There isn’t an exact one‑to‑one equivalent to STSPIN840. Comparable stepper‑driver ICs from other vendors include:
- TI: DRV8825, DRV8711
- Allegro: A4988, A4983
- Trinamic: TMC2100, TMC2208, TMC2209
These offer similar microstepping and current‑range capabilities, but check each part’s voltage/current ratings and features to match your application.
