NJM2644 www.
DataSheet4U.
com Two-phase Unipolar DC Brushless Motor Pre-Driver IC s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJM2644 is a 2-phase DC brushless motor pre-driver IC.
It incorporates Lock Detect and Auto Protection circuit for safety operation.
Especially, 1:10 ON/OFF duty ratio while motor is locked reduces heat generation in motor windings.
Moreover, the pin is compatible with 12V LA output NJM2644M NJM2644RB1 two-phase pre-driver NJM2641.
It is suitable for 12V fan motor applications.
s FEATURES • Operating Voltage VDD=4 to 14V • Absolute Maximum Voltage 15V • Internal Lock Detect / Auto Protection Release Circuit • FG Output Terminal • Package Outline DMP8 / TVSP8 s BLOCK DI...
