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); 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 Monolithic Digital IC Single-Phase Full-Wave Fan Motor Driver Ordering number : EN8794B |
