1 / 19 page DRV8832 www.ti.com SLVSAB3F – MAY 2010 – REVISED FEBRUARY 2012 LOW-VOLTAGE MOTOR DRIVER IC Check for Samples: DRV8832 1 FEATURES 2 • H-Bridge Voltage-Controlled Motor Driver • Fault Output – Drives DC Motor, One Winding of a Stepper • Thermally Enhanced Surface Mount Packages Motor, or Other Actuators/Loads APPLICATIONS – Efficient PWM Voltage Control for Constant Motor Speed With Varying Supply Voltages • Battery-Powered: – Low MOSFET On-Resistance: – Printers HS + LS 450 m Ω – Toys • 1-A Maximum DC/RMS or Peak Drive Current – Robotics • 2.75-V to 6.8-V Operating Supply Voltage – Cameras Range – Phones • 300-nA (Typical) Sleep Mode Current • Small Actuators, Pumps, etc. • Reference Voltage Output • Current Limit Circuit DESCRIPTION The DRV8832 provides an integrated motor driver solution for battery-powered toys, printers, and other low-voltage or battery-powered motion control applications. The device has one H-bridge driver, and can drive one DC motor or one winding of a stepper motor, as well as other loads like solenoids. The output driver block consists of N-channel and P-channel power MOSFET ’s configured as an H-bridge to drive the motor winding. Provided with sufficient PCB heatsinking, the DRV8832 can supply up to 1-A of DC/RMS or peak output current. It operates on power supply voltages from 2.75 V to 6.8 V. To maintain constant motor speed over varying battery voltages while maintaining long battery life, a PWM voltage regulation method is provided. An input pin allows programming of the regulated voltage. A built-in voltage reference output is also provided. Internal protection functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature protection. The DRV8832 also provides a current limit function to regulate the motor current during conditions like motor startup or stall, as well as a fault output pin to signal a host processor of a fault condition. The DRV8832 is available in tiny 3-mm x 3-mm 10-pin MSOP and WSON packages with PowerPAD ™ (Eco-friendly: RoHS & no Sb/Br).
