SGM42500 3.6A Brushed DC Motor Driver, 7-40V H-Bridge, SOIC-8, for Robotic Vacuum Cleaners, Printers and Industrial Pump Valves

I. SGM42500 Product Overview

The SGM42500 is a high-performance brushed DC motor driver from SGMICRO. It features an H-bridge topology and integrates four N-MOSFETs, providing a peak output current of up to 3.6A over a wide voltage range of 7V to 40V. The typical on-resistance of this device is only 0.41Ω (HS + LS, +25℃), which significantly reduces power loss and temperature rise, providing a cost-effective domestic solution for small and medium-power motor drive scenarios.

The SGM42500 supports IN1/IN2 PWM control interfaces, allowing the motor to rotate forward, reverse, brake, and regulate speed using the input pins. Meanwhile, the device is equipped with a VREF pin, which can use the controller's DAC output or the RC-filtered PWM signal to adjust the PWM current limit and motor torque in real time to meet the requirements of precise control under different load conditions.

II. SGM42500 Core Features and Technological Advantages

It integrates a complete protection mechanism. The SGM42500 features multiple built-in protection functions such as overcurrent protection (OCP), short-circuit protection, under-voltage lock-out (UVLO), and thermal shutdown (TSD). After the fault condition is resolved, the device can automatically resume normal operation without external intervention, effectively improving system reliability.

Low power standby mode. The device supports low-power standby mode, significantly reducing system static power consumption when the motor is stopped, making it particularly suitable for battery-powered portable devices and IoT terminal applications.

Compatible with mainstream solutions, domestic alternatives are preferred. The SGM42500 is comparable to classic international brand models such as DRV8870 and A4950 in terms of pin definition and function, providing engineers with a low-risk alternative to domestic production and achieving a balance between supply chain security and cost optimization.

Environmentally friendly packaging. It adopts SOIC-8 exposed pad packaging, taking into account both heat dissipation performance and PCB footprint, and meets RoHS environmental requirements.

III. SGM42500 Typical Application Scenarios

Robot vacuum cleaners and intelligent cleaning equipment. The SGM42500's wide voltage input (7V~40V) and low power consumption characteristics enable it to effectively adapt to the driving needs of the edge brush motor of robotic vacuum cleaners. In practice, its supply current can be as low as 2.3mA, and its withstand voltage can exceed 30V, meeting the operating current requirements of the edge brush motor of less than 1A.

Printers and office equipment. Scenarios such as the paper feed motor and typewriter motor in thermal printers and inkjet printers require precise PWM speed regulation and rapid braking capabilities. The SGM42500's IN1/IN2 interface, combined with real-time adjustable current limiting function, can effectively control the printhead movement accuracy.

Industrial pump and valve control. In the field of industrial automation, this device can be used for bidirectional drive of small pumps, solenoid valves and actuators. Its wide temperature operating range (-40℃ to +125℃) ensures stable operation in harsh industrial environments.

Vacuum cleaners and household appliances. Handheld vacuum cleaners, power tools, and other devices have high requirements for the peak current capacity and thermal performance of their drivers. The SGM42500's 3.6A peak current and 0.41Ω low on-resistance provide reliable driving support for such applications.
