Texas Instruments TMAG5230 Z-Axis Hall-Effect Switch
Texas Instruments TMAG5230 Z-Axis Hall-Effect Switch is ideal for magnetic position-sensing applications. The switch is available in an ultra-small form factor DSBGA (WCSP) package that supports both omnipolar and unipolar outputs. The TMAG5230 supports multiple combinations of high-sensitivity thresholds and various sampling rates, enabling flexible system design for magnet selection, sensitivity, and power requirements.
The TI TMAG5230 Z-Axis Hall-Effect Switch is available with a push-pull output to eliminate the need for an external pull-up resistor, or with an open-drain output that allows using an I/O voltage different from the TMAG5230 supply. The open-drain output can support voltages above VCC, eliminating the need for power sequencing.
