TLE4946-2L
Specification
Attention: Stresses above the max. values listed here may cause permanent damage to the device.
Exposure to absolute maximum rating conditions for extended periods may affect device
reliability. Maximum ratings are absolute ratings; exceeding only one of these values may
cause irreversible damage to the integrated circuit.

Characteristics
Product characteristics involve the spread of values guaranteed within the specified voltage and ambient
temperature range. Typical characteristics are the median of the production (at Vs = 12V and TA= 25°C).

1) To operate the sensor at the max. switching frequency, the value of the magnetic signal amplitude must be 1.4 times higher
than for static fields.
This is due to the - 3 dB corner frequency of the low pass filter in the signal path.
2) Systematic delay between magnetic threshold reached and output switching
3) Jitter is the unpredictable deviation of the output switching delay
4) Time from applying VS ≥ 2.7 V to the sensor until the output state is valid
5) Thermal resistance from junction to ambient
