Q1. Where I can download the GUI that accompanies the evaluation board?
A1. The GUI tool can be downloaded from this link
Q2. I would like to write some embedded code for the ADE1202. Do you have any driver code available?
A2. Yes, the ADE1202 driver code is written and compiled using the MBED online compiler. Follow this link to get the driver code. The code is written for the SDP-K1 evaluation board and can be connected to the ADE1202 evaluation board.
Q3. I would like to set the high current on time in the PL_HIGH_TIME register for 200ms to dissipate a large capacitive load. How can I do this?
A3. The maximum allowed high current time is 40.95 ms. The IC was designed with this limitation in mind to ensure the thermal limitations of the package are not breached. Another way to dissipate capacitive loads is to use a shorter pulse time and higher pulse current.
Q4. What is the package creepage on the ADE1202?
A4. The ADE1202 has an LGA package with 6.8mm creepage
Q5. On the ADE1202, can the you configure a different pulse current level for CH1 and CH2?
A5. No. There is no option to set different current levels. Both pulse current levels will be the same.
Q6. Can the SPI operate at 5V?
A6. No. The SPI must be within the absolute max limits which is VDD + 0.3V
Q7. I have configured the part, but the binary input is not active. How can I fix it?
A7. After configuring the registers on the ADE1202 write 0xADE1 to CONFIG_LOCK register for configuration setting to take effect.
Q8. How long does it take for a register write to take effect?
A8. It takes 100us for a register write to take effect when writing across the isolation barrier.
Q9. I have modified some register configurations of the ADE1202 while in operation. I notice some unexpected pulse on Dout. What is wrong?
A9. ADI recommends issuing a software reset of the part before modifying any configuration settings. This will flush out all internal filters and ensure correct operation of the part.
Q10. Does ADE1202 work with enhancement mode or depletion mode FETs?
A: ADE1202 works with enhancement mode FET’s which are more common than depletion mode FET’s.
