LB11660RV-MPB-H

Half-pre Motor Driver Single-Phase Full-Wave Drive, for Fan Motor

ON Semiconductor 

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).
