LB11961V Overview
EN8794B LB11961V Monolithic Digital IC Single-Phase Full-Wave Fan Motor Driver http://onsemi. 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 puter power supply systems and CPU cooling fan systems.
LB11961V Key Features
- Single-phase full-wave drive (16V, 1.0A transistors are built in)
- Built-in variable speed function controlled by a thermistor input
- Built-in regenerative diode (Di); only requires a minimal number of external ponents
- 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
