DIODES has announced the AH5798, an all-in-one motor controller IC for single coil low power brushless DC fans and motors.
According to Diodes, the AH5798 provides drive protection and interface functionality to substantially reduce component counts and PCB area in small fan and motor applications.
The AH5798 integrates a full-bridge driver, which means the controller requires no external driver components but supports average source and sink currents up to 300mA.
Diodes says the controller's locked rotor detection and self restart functions help protect the coil from over-heating or burning out and initiate automatic restart once the locked rotor is released. The AH5798 also includes a tachometer open-drain output to make the device easier to interface for external status and speed monitoring.
The chip operates at 1.8V to 5.5V and has an ambient operating temperature rating of -40ºC to +105ºC.
Diodes products are distributed in Australia by Arrow Electronics Australia, Digi-Key Corporation, Farnell and Future Electronics.
