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. Built-in HB Minimum speed setting pin (allows full-speed mode operation at startup) Operates in full-speed mode when the thermistor is removed. Built-in lock protection and automatic recovery circuits FG (speed detection) and RD (lock detection) outputs Built-in thermal shutdown circuit
