3 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).
