TLP3547 Evaluation Board Review [Copy link]

 After getting the side panel, I have been busy with other projects and have no time to test it. Yesterday, I took some time to simply test the basic performance of the first-line TLP3547 module. Test method: Connect the signal generator to pins 1 and 2 of the evaluation board, and input a pulse waveform of a certain frequency; connect pins 3 and 4 to the buzzer range of the multimeter. Test process: 1. Modulate the frequency of the signal generator to 1hz and the amplitude to 100mV. 2. Slowly increase the amplitude. When it reaches 3.48V, the buzzer starts to sound. Test results: The minimum switching voltage of the relay is 3.48V. When in use, it can be directly controlled by an MCU with a 5V voltage output. This relay is small in size, low on-voltage, and low power. It is suitable for use in low-frequency, low-power module components.
