Operating Range

The following operating conditions must not be exceeded in order to ensure correct operation of the TLE4961-5M.

All parameters specified in the following sections refer to these operating conditions unless otherwise mentioned.

Electrical and Magnetic 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 and correspond to VDD = 12 V and

TA = 25°C. The below listed specification is valid in combination with the application circuit shown in Figure 3-1

and Figure 3-2

Magnetic signal input frequency2)

2) For operation at the maximum switching frequency the magnetic input signal must be 1.4 times higher than for static fields.

This is due to the -3dB corner frequency of the internal low-pass filter in the signal path.
