Introduction The Si890x are isolated ADCs suitable for low-frequency analog data acquisition applications. These devices integrate an isolated 10-bit SAR ADC with I2C, UART, or SPI serial communication ports. Isolation ratings of 2.5 or 5 kV are available. See the Si8900 data sheet for details. 2. Kit Contents The Si890xPWR-EVB Evaluation kit contains the following items: Si890xPWR-EVB evaluation module containing: High voltage 110 V/220 V ac line current and voltage measurement circuit with 3.3 Vpp analog output signals Isolated 10-bit ADC with UART serial port Si8900 Isolated 10-bit ADC with I2C serial port Si8902 Isolated 10-bit ADC with SPI serial port C8051F007 mixed-signal MCU master controller AC line-side bias supply Si8901 2.1. Hardware Overview The Si890xPWR-EVB (Figure 1) demonstrates 50/60 Hz ac line voltage and current measurements. This EVB is housed in a plastic case with recessed connectors to protect against user electrical shock. The Si890x accepts a 110 or 220 Vac input and supports load currents up to 10 A (max). The on-board line side circuit interface measures ac voltage and current, which is then digitized by the Si890x on-chip 10-bit ADC. The resulting converted data is then transmitted through the output side isolated serial port to the on-board master processor (C8051F007 MCU). The C8051F007 converts the serial data back to analog format where it is available to the user at the lowvoltage side of the evaluation module. Key features for this EVB include the following: EVB module measures ac line voltage (110 Vac or 220 Vac at 50/60 Hz) and ac line current (10 A max) 10-bit ADC with three input channels and selectable, isolated serial ports: UART (Si8900) or I2C (Si8901) or SPI (Si8902) High common mode transient immunity (CMTI): 35 kV/µs (min), 50 kV/µs (typ) Industrial temperature operating range (–40 to +85 °C) 60-year isolation barrier life at rated working voltage Safety certified (pending) CSA component notice 5A approval 60950, 61010, 60601 VDE/IEC 60747-5-2 UL1577 recognized: (Up to 5 kVrms for 1 minute) IEC Danger! High Voltage: Read instructions carefully. Do not operate this evaluation board unless it is housed in its plastic case and secured by the four screws.

The ac input barrier strip (TB-1, bottom side of board) is recessed to provide an extra margin of space between the housing exterior and the ac line connection. Safety Warning: The board MUST remain in the plastic enclosure whenever the ac line voltage is connected to the Si890x input terminals. 2 Rev. 1.1 Si890x-PWR-EVB 3. Required Equipment One dc regulated power supply capable of generating 2.7 V to 3.6 Vdc at 200 mA. Small hand tools: soldering iron, wire cutters, needle-nose pliers, wire stripper, screwdrivers. Minimum two-channel oscilloscope. 22-gauge stranded wire for low-voltage signal connector P1. A suitable ac load (e.g., power resistor, lamp with or without dimmer, max current of 10 A).

Hardware Setup and Demo Safety Warning: Remove power from the board before proceeding! Setting-up the Si890xPWR-EVB evaluation module requires configuring the jumper options, then connecting the input and output cables with the ac line disconnected and the external dc power supply off. EVB setup and configuration is as follows: 1. Remove the four screws from the bottom of the EVB plastic enclosure and remove the top cover. 2. The default factory EVB settings enable the Si8900 (UART). Verify the factory jumper option settings using Table 1 (use Figure 3 to locate the configuration headers). If so desired, the Si8901 or Si8902 can be selected instead of the Si8900 by following the instructions in Paragraph 3. Otherwise, skip to paragraph 4. 3. Configuring an Isolated ADC: a.Choose the isolated ADC to be enabled (Note that only one ADC can be in service at a time). b.Headers J2, J3 and J4 route the ac line-side VDD, AIN0, and AIN1 corresponding pins of the desired Si890x device (Input AIN0 typically measures line input voltage, and AIN1 typically measures ac line current). For example, if the Si8902 is the device to be used, insert shorting jumpers between pins 1 and 2 on headers J2, J3, and J4 as shown in the “Selecting Si8902” drawing of Figure 4. Configurations for selecting the Si8900 and Si8901 are also shown in Figure 4.

If using the Si8900, install shorting jumpers on pins 1 and 2 on both J7 and J8. 2. If using the Si8901, install shorting jumpers on pins 5 and 6 on both J7 and J8. 3. If using the Si8902, install shorting jumpers on pins 3 and 4 on both J7 and J8. Example: Si8900 Rx pin is routed to the D0 pin of P1, and Tx is routed to the D1 pin of P1 when connected as shown.

Locate the six-screw ac line terminal block (TB1) on the right side of the circuit board. With the ac line disconnected from the outlet, loosen the screws on TB1 corresponding to AC_H and GNDA, as shown in Figure 6. Strip 1/4 inch of insulation from the “hot side” of the ac wire and insert the wire through the enclosure opening and into the AC_H terminal block opening. Be sure there is no bare wire exposed. Tighten the screw on the terminal block to secure the AC_H wire. Repeat this procedure for the GNDA wire connection to TB1. 5. Locate the ac output (load) terminals AC_OUT and AC_H on TB1 as shown in Figure 6. With the ac line disconnected from the outlet, loosen the screws on TB1 corresponding to AC_OUT and AC_H, as shown in Figure 3. Strip 1/4 inch of insulation from the “hot side” of the ac wire and insert the wire through the enclosure opening and into the AC_H terminal block opening. Be sure there is no bare wire exposed. Tighten the screw on the terminal block to secure the AC_H wire. Repeat this procedure for the AC_OUT wire connection to TB1.

Connect the loose ends of the AC_OUT and AC_H wires from TB1 to the load (e.g. power resistor, lamp, etc.). 7. Replace the top cover of the enclosure and secure with four screws. Examine the ac line side of the enclosure and verify that the ac lines external to the enclosure have no bare wire exposed. 8. Locate the male connector that mates to output side connector P1 (see Figure 5) and test fit to connector to P1. Remove the connector from P1. Cut nine equal lengths of AWG28 wire, each one eight inches long. Strip 1/4 inch of insulation from each end of all eight wires. Solder one end of each wire to each wire to the male connector. When soldering is complete, plug the male connector into P1. 9. Obtain an external adjustable power supply (bench or lab supply), but do not connect it to the Si890x EVB yet. With no load attached, turn the power supply on and set the output to 3.3 V. Turn the power supply off and discharge its outputs by shorting the positive and negative terminals together. 10.Connect the dc supply outputs to the VDDB and GNDB input pins of P1, as shown in Figure 7. 11. Turn the oscilloscope on and connect oscilloscope probes to the DAC0 and DAC1 output pins of P1, as shown in Figure 7.

With the load engaged, the voltage (blue) and current (yellow) waveforms will appear on the oscilloscope as shown in Figure 8.
