5 Using NXP PCAL6416AEV with customer system
1. Connect input power for VDDI and VDDP
a. VDDI power is for I
2
C-bus and internal logic of PCAL6416AEV. VDDI can be input
from external power by TP3.
b. VDDP power is for I/O ports of PCAL6416AEV. VDDP can be input from external
power by TP2.
2. Set jumpers:
•
J1 = open for external power for VDDP_IN
•
J3 = enable power for VDDP
•
J4 = open for external power for VDDI_IN
•
J5 = enable power for VDDI
•
J6 = 3-4 for PCAL6416AEV slave address = 0x010-0000
•
TP2 = external power 3.3V for VDDP_IN with TP5 (GND)
•
TP3 = external power 3.3V for VDDI_IN with TP4 (GND)
3. Test current of VDDI and VDDP
•
Use multi-meter at J3 for VDDP and J5 for VDDI.
4. Test GPIO outputs and Interrupt
a. Put jumper on J4 to enable power of D1 LED indicators for INT and PWR
