AC Voltage Zero Cross Detection IC BM1Z002FJ Evaluation Board Notice ＜High Voltage Safety Precautions＞ ◇ Read all safety precautions before use Please note that this document covers only the BM1Z002FJ evaluation board (BM1Z002FJ-EVK-001) and its functions. For additional information, please refer to the datasheet. To ensure safe operation, please carefully read all precautions before handling the evaluation board Depending on the configuration of the board and voltages used, Potentially lethal voltages may be generated. Therefore, please make sure to read and observe all safety precautions described in the red box below. Before Use [1] Verify that the parts/components are not damaged or missing (i.e. due to the drops). [2] Check that there are no conductive foreign objects on the board. [3] Be careful when performing soldering on the module and/or evaluation board to ensure that solder splash does not occur. [4] Check that there is no condensation or water droplets on the circuit board. During Use [5] Be careful to not allow conductive objects to come into contact with the board. [6] Brief accidental contact or even bringing your hand close to the board may result in discharge and lead to severe injury or death. Therefore, DO NOT touch the board with your bare hands or bring them too close to the board. In addition, as mentioned above please exercise extreme caution when using conductive tools such as tweezers and screwdrivers. [7] If used under conditions beyond its rated voltage, it may cause defects such as short-circuit or, depending on the circumstances, explosion or other permanent damages. [8] Be sure to wear insulated gloves when handling is required during operation. After Use [9] The ROHM Evaluation Board contains the circuits which store the high voltage. Since it stores the charges even after the connected power circuits are cut, please discharge the electricity after using it, and please deal with it after confirming such electric discharge. [10] Protect against electric shocks by wearing insulated gloves when handling. This evaluation board is intended for use only in research and development facilities and should by handled only by qualified personnel familiar with all safety and operating procedures. We recommend carrying out operation in a safe environment that includes the use of high voltage signage at all entrances, safety interlocks, and protective glasses. www.rohm.com © 2018 ROHM Co., Ltd.

HVB01E User’s Guide AC/DC Converter AC Voltage Zero Cross Detection IC BM1Z002FJ Evaluation Board BM1Z002FJ-EVK-001 General Description This evaluation board outputs a signal indicating when there is a zero voltage crossing from an input AC voltage from 90 VAC to 264 VAC. The BM1Z002FJ with the very few external components, will output a signal which is synchronous and offset in time if configured to do so, indicating when the two phases of the input AC signals are crossing 0V relative to one another. The advantage of the BM1Z002FJ is that it will provide the desired output signal while consuming less than 1/10 of the current, using fewer components, and at higher precision and repeatability as compared to a conventional zero cross detection circuit ACOUT Eval Board AC In GND 1.5 6 1 5 0.5 4 0 3 -0.5 2 -1 1 -1.5 0 Figure 1.

(2) Connect the output pin (ACOUT-pin, COMMON pin as ground reference) to an Oscilloscope (Keep the ground isolated from AC Inputs and probes). (3) Connect the AC Input pins of the eval baord (CN1) to AC power supply output with pair of wires. (4) Connect oscilloscope probes to each of the AC Input pins, and connect the grounds for each probe to the Common or GND (Clarify which node per the notes about the schematic) pins on the eval board (5) Set the Oscilloscope to display the AOUT probe so that a 5V rail to rail signal displays correctly and so that AC probe1 AC probe2 is displayed (6) Turn on the AC power supply (7) Confirm the output waveform ACOUT is synchronized with the AC input voltage. Caution:To avoid the electrical shock , please keep AC Power supply being isolated. Figure 2.

Output a zero cross point of the AC voltage from ACOUT pins by monitoring the voltage between VH_AC1 pins and the VH_AC2 pins of IC1. The input pins VH_AC1 and VH_AC2 can tolerate up to 600V relative to one another. This results in a high reliabitity circuit using very little power. The ACOUT output pin of the eval board has 5V as it's high output level and 0V as it's low level. This voltage level is set by the output of the Power supply circuit. It can be modified to span a different voltage range. Please request guidance from your local Rohm support person if a different operating voltage range is required.

Populating the R3 location with the values shown above will result in a shift in time between the detected Zero Crossing and when the ACOUT signal changes state. Note that the ACOUT change can be advanced or occur before (negative delay) the zero crossing. © 2023 ROHM Co., Ltd. 5/10 No. 62UG076E Rev.003 2023.01 User’s Guide BM1Z002FJ-EVK-001 Measurement Data 1 Input output waveform ( Measurement Diagram of is Figure 2. ) R3 : OPEN VACOUT VACOUT 5 V / Div 5 V / Div VIN VIN 100V / Div 100 V / Div Figure 7.
