9 / 18 page 9/18 VND600SP 1 µC I/Os PROTECTION: If a ground protection network is used and negative transient are present on the VCC line, the control pins will be pulled negative. ST suggests to insert a resistor (Rprot) in line to prevent the µC I/Os pins to latch-up. The value of these resistors is a compromise between the leakage current of µC and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of µC I/Os. -VCCpeak/Ilatchup ≤ Rprot ≤ (VOHµC-VIH-VGND) / IIHmax Calculation example: For VCCpeak= - 100V and Ilatchup ≥ 20mA; VOHµC ≥ 4.5V 5k Ω ≤ R prot ≤ 65kΩ. Recommended Rprot value is 10kΩ. 0246 8 10 12 14 16 3000 3500 4000 4500 5000 5500 6000 6500 min.Tj=-40°C max.Tj=-40°C min.Tj=25...150°C max.Tj=25...150°C typical value Figure 3: IOUT/ISENSE versus IOUT IOUT/ISENSE IOUT (A) |
