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).

DRV8832 www.ti.com SLVSAB3H – MAY 2010 – REVISED OCTOBER 2013 FUNCTIONAL DESCRIPTION Power Supervisor The DRV8832 is capable of entering a low-power sleep mode by bringing both of the INx control inputs logic low. The outputs will be disabled Hi-Z. In order to exit the sleep mode, bring either or both of the INx inputs logic high. This will enable the H-bridges. When exiting the sleep mode, the FAULTn pin will pulse low.
PAGE 8
DRV8832 SLVSAB3H – MAY 2010 – REVISED OCTOBER 2013 www.ti.com Because of the sleep mode functionality described previously, when applying an external PWM to the DRV8832, hold one input logic high while applying a PWM signal to the other. If the logic input is held low instead, then the device will cycle in and out of sleep mode, causing the FAULTn pin to pulse low on every sleep mode exit. Voltage Regulation The DRV8832 provides the ability to regulate the voltage applied to the motor winding.

DRV8832 www.ti.com SLVSAB3H – MAY 2010 – REVISED OCTOBER 2013 Current Limit A current limit circuit is provided to protect the system in the event of an overcurrent condition, such as what would be encountered if driving a DC motor at start-up or with an abnormal mechanical load (stall condition). The motor current is sensed by monitoring the voltage across an external sense resistor.

DRV8832 SLVSAB3H – MAY 2010 – REVISED OCTOBER 2013 www.ti.com THERMAL INFORMATION Thermal Protection The DRV8832 has thermal shutdown (TSD) as described above. If the die temperature exceeds approximately 160°C, the device will be disabled until the temperature drops to a safe level. Any tendency of the device to enter TSD is an indication of either excessive power dissipation, insufficient heatsinking, or too high an ambient temperature.
