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.
