Description
The AH5792 is a single chip solution for driving single-coil brush-less DC fans and motors. The AH5792 employs a bidirectional full bridge driver output stage for single coil fan motor applications. The device includes features such as Rotor Lock Protection with rotor lock detection and automatic self-restart to avoid damage to the coil when the rotor is blocked. The AH5792 also offers an externally control°C Tachometer (Frequency Generator Pin) open -drain output which makes it easier to connect with external interface such as hardware monitoring. The FG is half (1/2) the magnetic change frequency. The devices are packaged in SOT553 and SOT89-5L small outline packages for applications such as small motors like vibration motors or ultra thin cooling fans.
