Description

The AWD8231A device is an integrated motor driver, which is equipped with an N-channel H-bridge, a charge pump, current-sensing feedback, current regulation and protection circuits. The charge pump boosts efficiency by supporting N-channel MOSFET half bridges and 100% duty cycle driving. The internal current mirror architecture on the IPROPI pin realizes the functions of current sensing and regulation, which eliminates the necessity of using large power shunt resistors, thus saving the board area and reducing the system cost. The IPROPI current-sensing output enables the microcontroller to detect motor stall or changes in load conditions. The external voltage reference pin VREF can determine the threshold of current regulation during startup and stall events without the intervention of the microcontroller. The low-power sleep mode achieves ultra-low quiescent current consumption by shutting down most of the internal circuits. Its internal protection features include power undervoltage lockout, output overcurrent and device overheating protection.
