LB11660FV
Overview
Single-Phase Full-Wave Fan Motor Driver
The LB11660FV is a single-phase bipolar drive half-predriver motor driver that can easily implement a direct PWM driver motor driver circuit with excellent efficiency. The LB11660FV is particularly well suited for the miniature fans used in servers.
Features
- Single-phase full-wave drive (15V, 1.5A transistors are built in) Half predriver with integrated high side transistor
- Built-in variable speed function controlled by an external input The LB11660FV can implement quiet, low-vibration variable speed control using externally clocked high side transistor direct PWM drive.
- Minimum speed setting pin
- Current limiter circuit (The limit value is determined by Rf; IO = 1A when RF = 0.5Ω)
- Built-in kickback absorption circuit
- Soft switching circuit makes low current consumption, low loss, and low noise drive possible at phase switching
- Built-in HB
- Built-in lock protection and automatic recovery circuits (built-in on/off ratio switching circuit controlled by the supply voltage)
- FG (speed detection) output
- Built-in thermal protection circuit (design guarantee)
