LB11961 Overview
.DataSheet.co.kr Ordering number : EN8793B Monolithic Digital IC 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 puter power supply systems and CPU cooling fan systems.
LB11961 Key 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 variabl
- 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
