Ordering number : EN8794B LB11961V Monolithic Digital IC Single-Phase Full-Wave Fan Motor Driver http://onsemi.
com Overview The LB11961V is a single-phase bipolar drive motor driver that easily implements direct PWM motor drive systems with excellent efficiency.
The LB11961V 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 LB11961V can implement quiet, low-vibration variable speed control using externally clocked high side transistor direct PWM drive.
• Built-in regenerative diode (Di); onl...
