LB1862M

Ordering number : EN5657 Monolithic Digital IC LB1862M Single-Phase Full-Wave Driver for Fan Motors Overview The LB1862M is a single-phase full-wave driver provided in a miniature package that is optimal for driving miniature fans such as CPU cooling fans. It provides motor drive with low switching noise and high efficiency. Package Dimensions unit: mm 3086A-MFP10S [LB1862M] Functions Supports both 5- and 12-V power supplies. Allows the use of reverse connection prevention diodes by including a regeneration circuit on chip. On-chip Hall amplifier with hysteresis characteristics (Supports commutator-free cores.) Lock protection and automatic recovery circuits Lock detection pin (Latch type – Low: drive, High: stopped) Supports low current drain in standby mode by providing a Hall bias pin and a start/stop pin.
