AN1762 APPLICATION NOTE

40/53

can also be used to provide a 5V voltage to external circuits (as, for example, the PractiSPIN ST7 board). In this

case the current that can be drawn form the board depends on the supply voltage and on R2 value.

Figure 44 to Figure 46 show the component placement and the two layers layout of the L6206N Evaluation

Board. A large GND area has been used, to guarantee minimal noise and good power dissipation for the device.

5.3.1 Important Notes

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

C6, C7 : recommended change to 5.6 nF for safe Overcurrent protection

R3, R4 : recommended change to 100 k for safe Overcurrent protection

R5, R6 : recommended change to 100 k if EN pins are driven from the CN5 connector (for example with Prac-

tiSPIN ST7 board), for safe Overcurrent protection

R20, R26 : set the maximum current obtainable through PractiSPIN (see PractiSPIN documentation)

R2 : recommended change to adequate value (depending on supply voltage) to obtain 5V across D3

JP2, JP3 : close to allow Overcurrent protection

JP4, JP5 : close for on-board OCD threshold adjusting through R7, R8

JP6, JP7 : close for use with PractiSPIN ST7 board
