Overview
Hall IC Fan Motor Driver DESCRIPTION SD1579 is a one-chip, two phase Hall IC fan driver use the advanced BICDMOS process.
Power output stage using LDMOS transistors, with low Rdson, low power dissipation and capable of withstanding high output drive current.
The driver of the motor circuit built-in Locked-rotor protection circuit, with automatic restart function.
Built-in voltage regulator circuit for the Hall sensor and amplifier circuit to provide internal power supply; The dynamic compensation circuit capable of providing good consistency and very small magnetic shift of the window over the whole temperature range,.
Built-in Zener output as the output protection management and in the supply-side built-in reverse protection diodes, which can effectively prevent damage when the power supply circuit is reverse.
TO - 94 APPLICATIONS * Dual coils brush-less DC fan; * Dual coils brush-less DC motor.
FEATURES * Built-in lock protection circuit; * Built-in Auto restart circuit; * Built-in Hall sensor with high stability of the dynamic compensation circuit; * Built-in Hall amplifier with hysteresis; * Built-in Zener Diodes protect outputs circuit; * Built-in Voltage Regulator circuit.
