onsemi LB11961V

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.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Stresses exceeding
