LB11961V: Single-Phase Full-Wave Fan Motor Driver

LB11961V is a single-phase bipolar drive motor that easily implements direct PWM motor drive systems with excellent efficiency. LB11961V is optimal for fan motor drive in personal computer power supply systems and CPU cooling fans.

Features
  • Built-in regenerative diode (Di)
  • Minimum speed setting pin
  • Single-phase full wave drive (16 V, 1.0 A transistors are built in)
  • Built-in variable speed function controlled by a thermistor input
  • Low vibration variable speed control using externally clocked high-side transistor direct PWM drive
  • Built-in HB
Benefits
  • Requires a minimal number of external components
  • Allows full-speed mode operation at startup
