The device integrates a DMOS H-bridge and current sense and protection circuitry. The device can be powered with a supply voltage between 6.5 V and 36 V, and is capable of providing an output current up to 2.8-A peak. A simple PHASE and ENABLE interface allows control of the motor speed and direction. A shunt amplifier output is provided for accurate current measurements by the system controller. The VPROPI pin outputs a voltage that is five-times the voltage seen at the SENSE pin. A low-power sleep mode is included which allows the system to save power when not driving the motor. 7.2 Functional Block Diagram 8 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Product Folder Links: DRV8801A-Q1 |
