TSH481 Ratio-metric Linear Hall Effect Switch TO-92S Pin Definition: 1. VCC 2. GND 3. Output Description TSH481 is a linear Hall-effect sensor which is composed of Hall sensor, linear amplifier and Totem-Pole output stage. It features low noise output, which makes it unnecessary to use external filtering. It also can provide increased temperature stability and accuracy. The linear Hall sensor has a wide operating temperature range of o o 40 C to +105 C, appropriate for commercial, consumer, and industrial environments. The high sensitivity of Hall-effect sensor accurately tracks extremely weak changes in magnetic flux density. The linear sourcing output voltage is set by the supply voltage and in proportion of variation of the magnetic flux density. Typical operation current is 2.5mA and operating voltage range is 3.0V to 6.5V Features ● ● ● ● ● ● Operating Voltage Range: 3.0V~6.5V Low-Noise Operation Linear output for circuit design flexibility Totem-Pole for a stable and accurate output Responds to either positive or negative magnetic flux density Robust ESD performance Ordering Information Part No. TSH481CT B0G Package Packing TO-92S 1kpcs / Bulk Bag Note: “G” denote for Halogen Free Product Application ● ● ● ● ● ● ● ● ● Current sensing Motor control Position sensing Magnetic code reading Rotary encoder Ferrous metal detector Vibration sensing Liquid level sensing Weight sensing Absolute Maximum Ratings (TA = 25oC unless otherwise noted) Characteristics Supply voltage Reverse voltage Magnetic flux density Output current Limit Value Unit VCC VCC 8 -0.5 Unlimited 10 V V G mA IOUT TOPR Operating Temperature Range -40 to +85 o C o -65 to +150 Storage temperature range TSTG C o 150 Maximum Junction Temp TJ C o 206 Thermal Resistance - Junction to Ambient RθJA C/W o 148 Thermal Resistance - Junction to Case RθJC C/W 606 Package Power Dissipation PD mW Note: Exceeding the absolute maximum ratings may cause permanent damage.
