LB11660RV
Monolithic Digital IC
Half-pre Motor Driver
Single-Phase Full-Wave Drive,
for Fan Motor
Overview
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.
Separately-excited upper TR direct PWM control method, enabling silent,
low-vibration variable speed control.
Lowest speed setting possible.
Current limiter circuit
(the circuit actuated at IO = 1A when Rf = 0.5, 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).
