DS20005347A-page 57 MCP3919 8.0 BASIC APPLICATION RECOMMENDATIONS 8.1 Typical Application Examples The application schematic referenced in Figure 8-1 can be used as a starting point for MCP3919 applications.The most common solution is to use one channel for voltage measurement and the rest of the channels for current measurement. Since all current lines are at the same potential, shunts can be used as current sensors, even if they do not provide any galvanic isolation. Since all channels are identical in the MCP3919, any channel can be chosen as the voltage channel (prefer- ably CH0 or CH2 since they are on the edges and can lead to a cleaner layout). FIGURE 8-1: MCP3919 Application Example Schematic. For polyphase metering applications, such as three- phase meters, it is recommended to use a current sensor that provides galvanic isolations: current transformers, Rogowski coils, Hall sensors, etc. RG9/3912_CS RG7/3912_SDO RG6/3912_SCK RG8/3912_SDI GND RA5/3912_RESET XTAL RD3/3912_CLKIN XTAL GNDA GND ADC CLOCK SELECT 10MHz X1 18pF 0603 C7 18pF 0603 C6 GND 1% 1M 0603 R20 10R 0603 R17 10R 0603 R7 0.1uF 0603 C3 10R 0603 R9 0.1uF 0603 C4 10R 0603 R6 10R 0603 R8 10R 0603 R10 10R 0603 R12 100R 0603 R5 10R 0603 R14 GNDA GNDA GNDA 0.1uF 0603 C5 2x3 X X J3 ECCP3 3.3D 3.3A GND GND GNDA GNDA GNDA GNDA CH0- CH0+ 1% 1k 0603 R18 1% 1k 0603 R65 GNDA 1% 1k 0603 R67 1% 1k 0603 R16 0.1uF 0603 C50 0.1uF 0603 C47 2x3 J7 1x3 J20 1% 1k 0603 R66 1% 1k 0603 R64 GND GNDA GNDA GNDA GNDA CH1+ CH1- 1% 1k 0603 R69 1% 1k 0603 R71 GNDA 1% 1k 0603 R73 1% 1k 0603 R68 0.1uF 0603 C52 0.1uF 0603 C51 2x3 J21 1x3 J22 1% 1k 0603 R72 1% 1k 0603 R70 GND GNDA GNDA GNDA GNDA CH2- CH2+ 1% 1k 0603 R75 1% 1k 0603 R77 GNDA 1% 1k 0603 R79 1% 1k 0603 R74 0.1uF 0603 C54 0.1uF 0603 C53 2x3 J23 1x3 J24 1% 1k 0603 R78 1% 1k 0603 R76 RA14/3912_DR ADC CH0+ CH0- CH1- CH1+ CH2+ CH2- NC 10 CH2- 7 REFIN+ 14 CH2+ 6 NC 8 NC 9 REFIN- 15 NC CH2- REFIN+ CH2+ NC NC REFIN- DGND 20 DR 18 OSC1/CLKI 21 OSC2 22 CS 23 SCK 24 SDO 25 SDI 26 RESET 27 DGND 17 DVDD 28 AVDD 1 AGND 16 CH0+ 2 CH0- 3 CH1- 4 CH1+ 5 NC 11 NC 12 NC 13 NC 19 MCP3919 U5 |
