DRV8833 Dual DC H-Bridge Speed Controller Motor Driver Module Price in Sri Lanka

The DRV8833 Dual DC H-Bridge Speed Controller Motor Driver Module is an ultra-compact, high-efficiency dual MOSFET H-bridge driver board engineered for low-voltage battery-powered robotics, micro-actuator control, and dual-phase bipolar stepper motor driving. Based on the Texas Instruments DRV8833 integrated circuit, it replaces legacy, power-wasting BJT-based drivers (like the L298N and L293D) by utilizing low-resistance N-channel power MOSFET H-bridges (RDS(on) ≈ 360 mΩ combined). Operating down to 2.7V, it delivers continuous drive currents up to 1.5A per bridge without requiring bulky heat sinks, while incorporating cycle-by-cycle current limiting, low-power sleep mode, and comprehensive thermal and short-circuit protections.

Features

• Ultra-Low Voltage Drop (High Efficiency): Employs modern low-RDS(on) DMOS power switches that waste virtually no energy compared to traditional L298N drivers (which lose 1.5V–2.5V in heat), making it ideal for maximizing battery life on 3.7V / 7.4V lithium-powered platforms.
• Native 3.3V & 5V Logic Compatibility: Input threshold levels accept standard 3.3V logic directly from ESP32, STM32, and Raspberry Pi Pico, as well as 5V logic from classic Arduino boards without level shifters.
• Active Fast Dynamic Braking: Pulling both directional control pins HIGH (or applying complementary PWM) shorts the motor terminals through the lower MOSFETs, braking the motor instantly without coasting.
• Ultra-Low Quiescent Sleep Mode: Bringing the dedicated sleep pin (ULT / SLEEP) low disables the internal charge pump and gate drivers, dropping standby current below 2 μA to prevent battery drain during inactive states.
• Parallelable H-Bridge Design: Bridge outputs and input control pins can be paralleled into a single, high-current output channel (up to 3A continuous) to drive larger single DC coreless or geared motors.

Common Applications

• Miniature Mobile Robotics: Driving differential N20 micro-metal gearmotors on line-following, maze-solving, and mini-sumo robotics platforms.
• Bipolar Stepper Actuation: Stepping 4-wire micro-stepper motors (such as those in optical CD/DVD drive carriages and miniature linear slides).
• Battery-Powered Toy & RC Conversions: Upgrading small RC vehicles, robotic grippers, and motorized camera pan/tilt mechanisms.
• Haptic & Vibration Actuators: Precision bi-directional drive of linear resonant actuators (LRA) and eccentric rotating mass (ERM) motors.
• Solenoid & Valve Driving: Actuating bi-directional latching solenoid valves and mechanical locking pins.

Usage Tips & Pinout Configuration

• Pin Assignment & Hook-Up:
  • VM: Motor Power Input (2.7V to 10.8V DC). Connect directly to your battery pack or motor power source.
  • GND: Common Ground. Must be tied to both the motor battery negative and your microcontroller ground.
  • IN1 / IN2: Logic inputs for Motor Channel A (OUT1 / OUT2).
  • IN3 / IN4: Logic inputs for Motor Channel B (OUT3 / OUT4).
  • ULT (Sleep Pin): Module Sleep control. Must be pulled HIGH (to 3.3V or 5V) to enable the driver. If left floating on breakout boards lacking a pull-up resistor, the chip stays in low-power sleep and will not output voltage.
  • EEP / FAULT (if broken out): Open-drain fault indicator. Pulls LOW during thermal shutdown, undervoltage, or overcurrent events.
• Control Logic Truth Table (Motor A Example):
  • IN1 = HIGH, IN2 = LOW → Forward Rotation.
  • IN1 = LOW, IN2 = HIGH → Reverse Rotation.
  • IN1 = HIGH, IN2 = HIGH → Brake (Motor terminals tied to ground, immediate deceleration).
  •  → Coast (High-impedance, motor free-wheels to a stop).
  • Speed Modulation: Apply a PWM signal (1 kHz to 20 kHz) to one pin while holding the opposite pin LOW (or apply inverted PWM for active braking drive).
• Decoupling & Motor Noise Suppression:
  • Always place a 100 μF to 220 μF electrolytic capacitor across the VM and GND lines close to the module to absorb inductive inductive kickback voltage spikes.
  • Solder a 0.1 μF (104) ceramic capacitor directly across each DC motor's terminals to suppress high-frequency brush arcing that can trigger spurious microcontroller resets.
• Current Limit Resistor Tuning (Isense):
  • Breakout boards usually come with pre-soldered surface-mount zero-ohm jumpers or 0.2Ω resistors at the current-sense pins (AISEN / BISEN)
