HALL IC
S-5711A Series
The S-5711A Series, developed by CMOS technology, is a Hall IC with a high-sensitivity and operates on a low current. The output voltage changes when the S-5711A Series detects the intensity level of flux density. Using the S-5711A Series with a magnet makes it possible to detect the open/close state in various devices. High-density mounting is possible by using the super-small SNT-4A, SOT23-3 packages. Also, the S-5711A Series is the most suitable for portable devices due to the low current consumption.
Features
• Built-in chopping stabilized amplifier • Applicable in various devices with wide range of option : Detection of both poles, south pole or north pole*1 : Active “L”, active “H” *1 : Nch open drain output, CMOS output • Wide power supply voltage range : 2.4 V to 5.5 V • Low current consumption : 5.0 µA typ., 8.0 µA max. • Range of operation temperature: −40°C to +85°C Small magnetic characteristics against temperature dependency • Small package : SNT-4A, SOT23-3 • Lead-free product *1. Selectable by option Please contact our sales office for options other than those specified in “ Product Name Structure”, “2. name list”.
