A3950SLPTR-T

‌A3950SLPTR-T Full-Bridge Motor Driver — Efficient, Reliable, Empowering Precision Motion Control‌

‌Product Overview‌

The A3950SLPTR-T from Allegro MicroSystems is a high-performance full-bridge motor driver designed for precision control of DC brushed motors, stepper motors, and small actuators. Featuring low on-resistance MOSFETs (RDS(on) as low as 0.5Ω), adjustable current limiting (±2.5A continuous output), and advanced protection features, it is ideal for demanding applications such as printers, office automation equipment, consumer electronics (e.g., smart home devices), and industrial machinery. Its compact PowerSSO-24 package supports surface mounting, simplifies PCB layout, and integrates thermal shutdown and undervoltage lockout (UVLO) to ensure long-term system stability.

‌Key Advantages‌

‌High-Efficiency Drive, Reduced System Losses‌

‌High Current Output‌: Supports ±2.5A continuous current (±3.5A peak) to directly drive small-to-medium motors without external power transistors.

‌Low Power Consumption‌: 0.5Ω MOSFET resistance minimizes heat generation, improving efficiency by 30% for battery-powered devices.

‌PWM Chopper Control‌: Adjustable chopping frequency (up to 250kHz) via external resistors enables silent operation and smooth torque control.

‌Smart Protection for System Safety‌

‌Overcurrent Protection (OCP)‌: Built-in current sensing and auto-shutdown prevent hardware damage from motor stall or short circuits.

‌Thermal Shutdown (TSD)‌: Automatically disables output at 150°C junction temperature, with self-recovery after cooling to extend lifespan.

‌Fault Diagnostics‌: FAULT pin provides real-time feedback on overheating or overcurrent events, accelerating system debugging.

‌Flexible Interface, Simplified Development‌

‌Multi-Voltage Compatibility‌: Directly interfaces with 3.3V/5V microcontrollers via DIR (direction), EN (enable), and PHASE control modes.

‌Easy Configuration‌: Set current limits with a single external resistor—no complex programming required.

‌Low Standby Power‌: Sleep mode current as low as 10μA extends battery life in portable devices.

‌Industrial Reliability, Cost-Optimized‌

‌Wide Operating Range‌: 8V to 40V input voltage supports automotive (12V/24V) and industrial power fluctuations.

‌Extended Temperature Support‌: Operates from -40°C to +125°C, with optional AEC-Q100 certification for automotive compliance.

‌Reduced BOM Cost‌: Integrated flyback diodes and gate drivers minimize external components, cutting system costs by 25%.

‌Typical Applications‌

‌Office Equipment‌: Laser printer paper feed motors, scanner lens drives

‌Smart Home‌: Motorized curtains, HVAC louvers, robotic vacuum wheel control

‌Industrial Automation‌: Conveyor speed adjustment, valve actuators, small robotic arm joints

‌Automotive‌: Sunroof adjustment, seat positioning, electronic throttle control

‌Medical Devices‌: Infusion pump flow control, micro-surgical tool drives

‌Why Choose A3950SLPTR-T?‌

‌Plug-and-Play Design‌: Deploy motor control solutions rapidly via hardware pin configuration—no complex algorithms needed.

‌Long-Term Supply Assurance‌: Allegro guarantees 10+ years of stable supply, eliminating production risks.

‌Global Technical Support‌: Asia-Pacific FAE team responds within 48 hours for EMI optimization, thermal layout, and more.
