NJM2646
Two-phase Unipolar DC Brushless Motor Pre-Driver IC
GENERAL DESCRIPTION
The NJM2646 is a 2-phase DC brushless motor pre-driver
IC with a totem-pole pre-driver for external power MOS-FET
driving. It has useful functions of Lock Detect and Auto
Protection circuit, which improve safety in motor locking. The
turn-on/turn-off ratio in the auto-recovery period is set in 1:10.
The NJM2644 is available in surface mount packages, an
8-lead DMP, SOP and thin type MSOP (TVSP), which
provides downsizing in the 12V fan motor applications. And it
is pin compatible with the NJM2640, 48V pre-driver.
