Product Overview
TMAG5170 is a Texas Instruments 3D linear Hall-effect Sensor built around independent X, Y, and Z Hall sensors. The device uses an integrated precision signal chain with 12-bit ADC resolution and supports single-axis conversion rates up to 20 ksps. Communication is through a 10 MHz SPI interface with cyclic redundancy check capability.
The device is supplied in a VSSOP (8), 3.00 mm x 3.00 mm nominal body size package, identified in the facts as DGK 8-pin VSSOP/MSOP. Pin functions include SCK, SDI, SDO, CS, VCC, GND, TEST, and ALERT. VCC supports a recommended 2.3 V to 5.5 V operating range, while the TEST pin should be grounded in application.
Measurement functions include selectable magnetic ranges for TMAG5170A1 and TMAG5170A2 variants, a built-in temperature sensor, ALERT interrupt or trigger behavior, and autonomous wake-up and sleep current in threshold detection mode. These parameters support 3D magnetic-field measurement, SPI-connected sensor nodes, threshold detection, and temperature-monitored magnetic sensing designs.
