8 / 28 page DRV8848 SLLSEL7 – OCTOBER 2014 www.ti.com 8 Detailed Description 8.1 Overview The DRV8848 is an integrated motor driver solution for two DC motors or a bipolar stepper motor. The device integrates two H-bridges that use NMOS low-side drivers and PMOS high-side drivers and current sense regulation circuitry. The DRV8848 can be powered with a supply range between 4 to 18 V and is capable of providing an output current to 1-A rms. A simple PWM interface allows easy interfacing to the controller circuit. The current regulation uses a fixed off-time (tOFF) PWM scheme. The current regulation trip point is controlled by the value of the sense resistor and the voltage applied to VREF. A low-power sleep mode is included, which allows the system to save power when not driving the motor. 8 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Product Folder Links: DRV8848 |
