Product details

Overview

EVSPIN948 from STMicroelectronics is a dual brushed DC motor driver evaluation board based on the STSPIN948 IC, designed for rapid prototyping of 5–58 V, up to 4.5 A_r.m.s. per channel motor control systems. It supports five driving modes, adjustable slew rate, integrated current sensing amplifiers (fixed gain), and full protection including overcurrent, UVLO, and thermal shutdown.

For engineers reviewing the EVSPIN948 datasheet, EVSPIN948 pinout, EVSPIN948 application, or EVSPIN948 equivalent, key selection considerations include Arduino® UNO R3/STM32 Nucleo compatibility, parallel-mode current doubling capability, external current control support via REFA/REFB, and TOFFA/TOFFB-configurable off-time current limiting.

Technical Context

The EVSPIN948 implements dual H-bridge motor drive using the STSPIN948 IC, which integrates two independent PWM-controlled drivers with embedded charge pumps (VBOOT, CP1/CP2), bootstrap capacitor management, and dedicated sense amplifier inputs (SENSEA/SENSEB) tied to REFA/REFB reference pins. Each channel features independent enable/fault reporting (EN/nFAULTA/B), phase/enable PWM inputs (PWM1A/PWM2A/PHA, PWM1B/PWM2B/PHB), and mode-select logic (MODE1/MODE2/MODE3).

It operates across 5–58 V supply (VS), supports adjustable output slew rate (SR pin), and enables flexible current regulation via TOFFA/TOFFB pins (off-time programmable current limiter) and OFFSETA/OFFSETB pins for offset calibration. The board routes all STSPIN948 signals-including VA/VB, LSSx, and nSTDBY-to accessible test points and headers for real-time monitoring and control.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	5 V to 58 V input - supports wide industrial and automotive battery-fed motor applications.
Max Phase Current	4.5 A r.m.s. per channel - enables driving medium-power brushed DC motors without external heatsinking.
Driving Modes	Five selectable modes (e.g., fast decay, slow decay, mixed decay) - configurable via MODE1/MODE2/MODE3 pins for torque/noise optimization.
Current Sensing	Two integrated amplifiers with fixed gain - provides direct analog current feedback at REFA/REFB for closed-loop control.
Slew Rate Control	Adjustable via SR pin - limits dv/dt to reduce EMI and MOSFET switching stress.

FAQ

What is the maximum continuous motor voltage supported by the EVSPIN948?

The EVSPIN948 evaluation board supports a VS supply range of 5 V to 58 V DC, as defined by the underlying STSPIN948 IC's absolute maximum rating. Operation above 58 V risks permanent damage to internal MOSFETs and charge pump circuitry. For sustained reliability, ST recommends staying within 55 V under load with adequate PCB copper area and thermal relief.

Can the EVSPIN948 drive a single motor with doubled current capacity?

Yes - the board supports parallel operation of both STSPIN948 channels to drive one brushed DC motor with up to 9 A r.m.s. peak current. This requires jumpering M1/M2 outputs, synchronizing PWM signals, and configuring identical TOFF and MODE settings on both sides. The board's layout and header assignments are explicitly designed to enable this configuration per DB5058 Rev 2.

How do the REFA and REFB pins function on the EVSPIN948?

REFA and REFB are buffered analog outputs from the STSPIN948's integrated current-sense amplifiers, each with fixed 20× gain referenced to SENSEA/SENSEB. They deliver real-time proportional voltage signals (0–VDD) representing phase current magnitude, enabling external ADC sampling or analog current limiting without additional op-amps or shunt signal conditioning.

Is the EVSPIN948 compatible with STM32CubeMX and STM32CubeIDE motor control tools?

Yes - ST provides dedicated firmware examples, HAL drivers, and Motor Control Workbench (MCSDK) integration for the EVSPIN948. Pin mappings align with standard Nucleo board GPIO definitions (e.g., PWM1A → TIMx_CH1, EN/nFAULTA → EXTI line), allowing automatic code generation and real-time parameter tuning via ST's official motor control ecosystem.
