Operating Range
The following operating conditions must not be exceeded in order to ensure correct operation of the TLE4998S8D.
All parameters described in the following sections refer to these operating conditions and each of the implemented
sensors IC’s if applicable or unless otherwise indicated.

2) For supply voltages > 12 V, a series resistance R_series ≥100 Ω is recommended
3) The open drain switch off, due to overvoltage on the V_DD line, can take place in the range of 16.65 V to 18.35 V, as defined
in Chapter 7.1 of the data sheet. The supply voltage range can be further extended until the overvoltage reset is taking
place, but the given accuracy see in the product data sheet is only applicable until the output switch off occurs
4) V_DDpon ... power-on reset level, see Table 5-1
5) Output protocol characteristics depend on these parameters, R_L must be according to max. output current
6) R_THja ≤ 150 K/W.
7) For reduced magnetic accuracy
Note: Keeping signal levels within the limits described in this table ensures operation without overload conditions.

1) This lifetime statement is an anticipation based on an extrapolation of Infineon’s qualification test results. The actual lifetime
of a component depends on its form of application and type of use etc. and may deviate from such statement. The lifetime
statement shall in no event extend the agreed warranty period.
