SD1579 Datasheet, PDF (1/7 Pages) Silan Microelectronics Joint-stock – Hall IC Fan Motor Driver

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;
TO - 94
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.
