Texas Instruments TMAG5133 High Sensitivity Hall-Effect Switch
Texas Instruments TMAG5133 High Sensitivity Hall-Effect Switch is a low-power in-plane hall-effect switch designed to replace TMR, AMR, and Reed switches. This hall-effect switch features a 1.65V to 5.5V supply voltage range, low power consumption, and operates at –40°C to 125°C temperature range. The TMAG5133 hall-effect switch offers two unipolar outputs or a single omnipolar output, which enables the device to react to external magnetic fields. The device is optimized for small form factors across industrial and consumer applications. This hall-effect switch is internally duty-cycled and includes a push-pull output to eliminate the need for an external pullup resistor. The TMAG5133 hall-effect switch is available in a 4-pin X1LGA, SOT-23 industry standard package. Typical applications include electricity meter tamper detection, electronic smart locks, smoke detector push buttons, water meters, gas meters, and door and window sensors.
