The AH5775 is a single-chip solution for driving single-coil, brushless, direct current (BLDC) fans and motors with 300mA continuous and 800mA peak motor current handling capability.

The integrated full-bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution.

To help protect the motor coil, AH5775 provides Rotor Lock Protection which shuts down the output drive if rotor lock is detected. The device automatically restarts when the rotor lock is removed. In overvoltage situations, the device shuts down the output drive and enters standby mode to help prevent overvoltage stress on the coil. Over-temperature shutdown provides thermal protection for the device.

AH5775 is available in TO94 package.
