LB11660RV: Half-pre Motor Driver, Single-Phase Full-Wave Drive, for Fan Motor
The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively.
Features- Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver.
- Variable speed control by an external signal.
- Lowest speed setting possible.
- Current limiter circuit(the circuit actuated at IO = 1A when Rf = 0.5Ω, Rf determines the limiter value.)
- Kickback absorption circuit built in.
- Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change.
- HB built in.
- Lock protection and automatic reset functions incorporated(including a circuit that changes the ON/OFF ratio according to the power supply voltage)
- RD (lock detection) output.
- Thermal protection circuit incorporated (design guaranteed).
