Linear sensors

Programmable dual channel linear Hall sensor with fast SPC interface

for high precision applications

Infineon’s TLE4999C8 is a programmable dual channel linear Hall sensor designed

to meet the requirements of safety critical automotive and industrial applications.

It is developed in full compliance with ISO 26262 by means of two sensor elements

included within one monolithic silicon design. In order to fulfill the state-of-the-art

safety requirements on system level and enable ASIL D system developments the

sensor cells are designed in a complementary way. Their signals follow two inde-

pendent analog paths. Each signal path has its own digital signal processing unit

to ensure maximum independency - redundancy, respectively. The sensor offers

a multi-point calibration with up to 9 selectable set points for enhanced lineariza-

tion of the output signal. For an easy and flexible adaptation to non-linearity of

magnetic circuit design, the chip provides 5 different calibration characteristics.

TLE4999C features a digital Short-PWM-Code (SPC) interface, with a bus-capability

for up to 4 sensor ICs on a single data output. The communication interface with

min. 0.5 µs unit time guarantees a fast transmission of complete 2 channel data

signal in less than 500 µs. The additionally implemented frame holder circuit en-

ables the synchronicity of multiple sensors (e.g. in combination of angle sensors)

via a SPC bus. The chip offers a 12, 14 and 16 Bit resolution of the output signal,

ensuring highest flexibility and superior noise performance.

Highest accuracy over a wide temperature range and lifetime is achieved by an

integrated digital temperature- and stress-compensation. The chip is available in a

thin 8-pin SMD single sensor package.
