Overview

The LV9005M is an optical sensor switch IC that is fabricated in a medium breakdown voltage BiCMOS process. The LV9005M circuit structure includes a high-gain optical sensor amplifier, a comparator, an oscillator circuit, output drivers, LED drivers, and a synchronous detection and delay circuit. The use of this IC and a minimal number of external components allows the implementations of multifunction high-sensitivity applications that previously would have only been possible with a custom optical-switch IC.

Functions and Features

• Can be used with a wide range of supply voltages; from 5 to 30 V.

• Low power

• Outputs can be selected as PNP or NPN circuit types.

• Built-in high-gain amplifier

• Built-in stability and output display functions

• Supports both reflection and through type applications, and supports both sense on light and sense on dark applications.

• Built-in OCP and power on reset functions

• Built-in three-level comparator

• Synchronous detection scheme adopted for robust performance in the presence of ambient and scattered light.

• External photodiode detection scheme allows the LV9005M to support a wide range of application areas.

• Miniature flat package supports high density printed circuit board mounting.

Applications

• Factory automation (detectors for many types of parts and products)

• Home security (doorway and window sensors)

• Office automation equipment
