LB11961
Overview
Single-Phase Full-Wave Fan Motor Driver
The LB11961 is a single-phase bipolar drive motor driver that easily implements direct PWM motor drive systems with excellent efficiency. The LB11961 is optimal for fan motor drive in personal computer power supply systems and CPU cooling fan systems.
Features
• Single-phase full-wave drive (16V, 1.0A transistors are built in) • Built-in variable speed function controlled by a thermistor input The LB11961 can implement quiet, low-vibration variable speed control using externally clocked high side transistor direct PWM drive. • Built-in regenerative diode (Di); only requires a minimal number of external components.
