Texas Instruments DRV8837CDSGR PWM motor driver, TI H-bridge IC
The DRV8837CDSGR from Texas Instruments is a low-voltage, H-bridge motor driver IC designed to control brushed DC motors or one bipolar stepper motor. It operates within a 1.8V to 11V supply range, delivering a continuous output current of 1.5A (2A peak). Packaged in a compact 8-pin WSON (DSG) with an exposed thermal pad, this driver integrates PWM current regulation and low-power sleep mode, making it ideal for battery-powered and space-constrained applications. The device features built-in protection circuits, including thermal shutdown, undervoltage lockout (UVLO), and overcurrent protection (OCP), ensuring reliable operation in demanding environments.
DRV8837CDSGR Key Features
The DRV8837CDSGR stands out with its high efficiency and low RDS(ON) (280mΩ typical per H-bridge), minimizing power dissipation. It supports PWM (Pulse-Width Modulation) control for precise speed regulation and offers phase/enable (PH/EN) or IN/IN control modes for flexible interfacing with microcontrollers. The motor driver also includes a low-power sleep mode (<100nA), significantly reducing idle power consumption. Its small form factor (2mm x 2mm WSON package) makes it suitable for portable and embedded systems where board space is limited.
DRV8837CDSGR Applications
This ti motor driver ic is widely used in consumer electronics, robotics, medical devices, and industrial automation. Typical applications include:
· Battery-powered toys & drones (for motor control in compact designs)
· Printers & scanners (paper feed and head movement control)
· Office automation equipment (actuators, small conveyors)
· Portable healthcare devices (adjustable beds, infusion pumps)
· IoT and smart home devices (smart locks, automated blinds)
