AN1451 APPLICATION NOTE

Figure 42. EVAL6208PD.

4.3.1 Important Notes

JP1 : close in INT position for use with PractiSPIN ST7 board

C12 : recommended change to 5.6 nF for safe Overcurrent protection

R7 : recommended change to 100 k for safe Overcurrent protection

R21 : recommended change to 100 k if EN pin is driven from the CN5 connector (for example with PractiSPIN

ST7 board) for safe Overcurrent protection

R8, R17 : set the maximum current obtainable through PractiSPIN (see PractiSPIN documentation)

R1 : recommended change to adequate value (depending on supply voltage) to obtain 5V across D2

4.3.2 Thermal Impedance

EVAL 6208PD has been thermally characterized. Figure 47 shows the thermal impedance junction to ambient

and the pulsed thermal impedance junction to ambient.
