Hardware Configuration
This section describes the board configuration using on-board jumpers and solder-bridges as well as the
SMBUS interface.
3.2.1
Power Supply (P1, P2, P3, P4)
Use a stabilized external power supply for the EVM board.
• Supply 3.3 V ± 0.3 V on P3 for chip operation.
• Supply 2.3 V – 3.6 V on P2 to supply the outputs Y0 and Y1.
• Supply 2.3 V – 3.6 V on P1 to supply the outputs Y2–Y5.
• Connect GND to P4.
Never supply more than 3.6 V on P1, P2, or P3.
3.2.2
Onboard Jumper (J12 and J10)
Use Jumper J10 to set the user programmable control input S0 to low or high.
Use Jumper J12 to set the user programmable control input S1 to low or high.
Default setting: J12 and J10 are not used.
Note:
S0 and S1 are logic high due to their internal pull-up resistors if J10 and J12 are not used.
