产品描述

The DRV8830 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 DRV8830 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. The output voltage is programmed via an I2C-compatible interface, using an internal voltage reference and DAC.

Internal protection functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature protection.

The DRV8830 is available in tiny 3-mm x 3-mm 10-pin MSOP and WSON packages with PowerPAD (Eco-friendly: RoHS & no Sb/Br).
