SD1579 Datasheet | Silan Microelectronics

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 pensation 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. - 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 pensation circuit; - Built-in Hall amplifier with hysteresis; - Built-in Zener Diodes protect outputs circuit; - Built-in Voltage Regulator circuit. .. - Built-in Reverse-voltage protection diode - Hall magnetic window, consistency and temperature stability; - Low Rdson, high drive current capability; - Wide operating voltage range, small quiescent current; ORDERING INFORMATION Part No. SD1579 Package TO-94 Marking 1579 Material Pb free Package Type Bulk HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://.silan..cn REV:1.0 2009.11.11 Page 1 of 7 BLOCK DIAGRAM ABSOLUTE MAXIMUM RATINGS Characteristics VCC Maximum Supply Voltage Maximum Output Current (Fault) Power Dissipation Operating Temperature Range ..
