描述 Description

The linear Hall IC TLE4998C8D has been designed specifically to meet the requirements of highly accurate angle and position detection. The sensor provides a digital SPC (Short PWM Code) signal, based on the standardized SENT (Single Edge Nibble Transmission, SAE J2716) protocol. The SPC protocol allows transmissions initiated by the ECU.
Two further operation modes are available:

? “range selection” for dynamically switching of the measurement range during operation

? “ID selection” to build a bus system with up to 4 IC’s on a single output line and a common supply, which can be individually accessed by the ECU.

特性 Features

? Integration of two individual programmable Linear Hall sensor IC’s with SPC (Short PWM Code) protocol with enhanced interface features based on SENT (Single Edge Nibble Transmission, defined by SAE J2716)
? 20-bit Digital Signal Processing (DSP)
? Digital temperature and stress compensation
? 16-bit overall resolution
? Operating automotive temperature range -40°C to 125°C
? Minimal drift of output signal over temperature and lifetime
? Programmable parameters stored in EEPROM with single-bit error correction:
? SPC protocol modes: synchronous transmission, dynamic range selection, ID selection mode
? Magnetic range, sensitivity (gain), offset, and polarity of the output slope
? Bandwidth
? Clamping levels
? Customer temperature compensation coefficients for all common magnets

? Re-programmable until memory lock
? Supply voltage 4.5-5.5 V (4.1-16 V extended range)
? Configurable magnetic range: ±50 mT, ±100 mT, or ±200 mT
? Reverse-polarity and overvoltage protection for all pins
? Output short-circuit protection
? On-board diagnostics (overvoltage, EEPROM error)
? Output of internal magnetic field values and temperature
? Programming and operation of multiple sensors with common power supply
? Two-point calibration of magnetic transfer function without iteration steps
