44 / 62 page  Data Sheet 44 Rev. 1.00 2020-02-24 BTS7200-4EPA PROFET™+2 12V Diagnosis 9.2 Diagnosis in ON state A current proportional to the load current (ratio kILIS = IL / IIS) is provided at pin IS when the following conditions are fulfilled: • The power output stage is switched ON with VDS < VDS(OLOFF) • The diagnosis is enabled for that channel • No fault (as described in Chapter 8.3) is present or was present and not cleared yet (see Chapter 9.2.2 for further details) If a “hard” failure mode is present or was present and not cleared yet a current IIS(FAULT) is provided at IS pin. 9.2.1 Current Sense (kILIS) The accuracy of the sense current depends on temperature and load current. IIS increases linearly with IL output current until it reaches the saturation current IIS(SAT). In case of Open Load at the output stage (IL close to 0 A), the maximum sense current IIS(EN) (no load, diagnosis enabled) is specified. This condition is shown in Figure 33. The blue line represents the ideal kILIS line, while the red lines show the behavior of a typical product. An external RC filter between IS pin and microcontroller ADC input pin is recommended to reduce signal ripple and oscillations (a minimum time constant of 1 µs for the RC filter is recommended). The kILIS factor is specified with limits that take into account effects due to temperature, supply voltage and manufacturing process. Tighter limits are possible (within a defined current window) with calibration: • A well-defined and precise current (IL(CAL)) is applied at the output during End of Line test at customer side • The corresponding current at IS pin is measured and the kILIS is calculated (kILIS @ IL(CAL)) • Within the current range going from IL(CAL)_L to IL(CAL)_H the kILIS is equal to kILIS @ IL(CAL) with limits defined by ΔkILIS The derating of kILIS after calibration is calculated using the formulas in Figure 32 and it is specified by ΔkILIS Figure 32 ΔkILIS calculation formulas The calibration is intended to be performed at TA(CAL) = 25°C. The parameter ΔkILIS includes the drift overtemperature as well as the drift over the current range from IL(CAL)_L to IL(CAL)_H. Diagnosis_dKILIS.emf |
