DRV8830中文资料7-V, 1-A H-bridge motor driver with speed regulation and I2C control数据手册TI规格书

描述 Description

The DRV8830 device 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 MOSFETs 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 through an I2C-compatible interface, using an internal voltage reference and DAC.Internal protection functions are provided for over current protection, short-circuit protection, undervoltage lockout, and overtemperature protection.The DRV8830 is available in a tiny 3-mm × 3-mm 10-pin VSON package and HVSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
