Infineon Technologies TLV493DA2BWXTMA1

Overview

TLV493DA2BWXTMA1 from Infineon is a low-power 3D Hall-effect magnetic sensor with I²C interface, measuring X/Y/Z magnetic flux density up to ±160 mT, delivering 12-bit resolution per axis plus 10-bit temperature sensing, and operating from 2.8 V to 3.5 V across –20°C to +85°C. It enables compact angular position sensing in joysticks, wearable devices, and smart home appliances.

For engineers reviewing the TLV493DA2BWXTMA1 datasheet, TLV493DA2BWXTMA1 pinout, TLV493DA2BWXTMA1 application, or TLV493DA2BWXTMA1 equivalent, key selection criteria include its 7 nA power-down current, programmable sensitivity (up to 30.8 LSB/mT), X-Y angular measurement mode, interrupt-driven measurement signaling, and SG-WFWLB-5-2 wafer-level chip-scale package.

Technical Context

The TLV493DA2BWXTMA1 integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed to a successive-approximation ADC, with integrated temperature sensing and configurable update rates. Its power mode control uses dual oscillators - a fast oscillator for measurement cycles and an ultra-low-power LP-OSC for standby - enabling dynamic switching between active and 7 nA sleep states.

Communication occurs via standard I²C (7-bit address 0x6A/0x6B), supporting clock stretching via the open-drain /INT pin. The sensor provides digital output with built-in demodulation, tracking, and biasing circuitry - eliminating external signal conditioning while maintaining immunity to stray fields due to its high full-scale range and on-chip calibration.

Key Specifications

Pinout & Package

TLV493DA2BWXTMA1 is housed in the SG-WFWLB-5-2 wafer-level chip-scale package (1.13 mm × 0.93 mm × 0.59 mm), featuring five terminals with no external leads - designed for direct die attach or fine-pitch SMT assembly.

FAQ

What is the default I²C address for TLV493DA2BWXTMA1?

The device ships with two factory-programmed I²C addresses: 0x6A for write operations and 0x6B for read operations. These are fixed and non-configurable. No external address pins exist, so multi-sensor configurations require software arbitration or sequential polling rather than hardware addressing.

Does TLV493DA2BWXTMA1 require external passive components for basic operation?

Yes - two external 1.2 kΩ pull-up resistors on SDA and SCL lines are mandatory for I²C compliance. A 100 nF decoupling capacitor between VDD and GND is also required, placed as close as possible to the package to ensure stable power delivery during measurement bursts and suppress switching noise.

Can the /INT pin be disabled or repurposed?

No - the /INT pin is a dedicated open-drain output that cannot be disabled or reassigned. It asserts low upon completion of each measurement cycle and may optionally be wired to SCL for clock stretching. Leaving it unconnected is acceptable if interrupt functionality is unused, but it must never be driven high externally.

How is temperature compensation handled in TLV493DA2BWXTMA1?

The sensor integrates a calibrated 10-bit temperature sensor that automatically samples after each X/Y/Z magnetic measurement. Firmware can read this value and apply linear or polynomial correction coefficients to magnetic data - no external sensor or calibration routine is needed, though coefficients must be determined per application during characterization.
