This post was last edited by 181084431 on 2018-9-8 09:44 Features of TLP3547: 1. High reliability and long service life 2. Small size and noise-free 3. Bidirectional conduction, replaceable relay ADC performance (reference voltage is 1.2V) 4. Supports 48-60V working contact voltage 5. Supports a maximum working current of 5A 6. 50m ohm on-resistance 7. 1-5mS on-time 8. Ultra-low drive power consumption 0.5mW 9. Support 2.5KVrms isolation Platform construction 1. Received the development board, it was well packaged, folded as follows: a) A bubble envelope + instruction manual + box with the development board 2.Make the corresponding test board (for the convenience of wiring and testing) 3. The final test platform (power supply + oscilloscope + development board) Response test 1. Pull-on response: within 5ms 2. Shut-off response: about 8ms Aging test 1. Using the company's equipment, the test framework is as follows, and the test is carried out through two programmable power supplies. a) Programmable power supply 1: used to control the on and off of the relay b) Programmable power supply 2: detect voltage and current to check whether the node is on or not [attach]374524 2. Use scripted programming to perform cyclic testing a) Load the control power supply to detect whether it is on (determine whether the voltage is less than a certain value) b) Turn off the control power supply to detect whether it is disconnected (determine whether the voltage is greater than a certain value) c) The test time is about 170ms, but the company's software will force a FAIL judgment if it is less than 1S, so a delay of 1000ms is added [attach]374520 3. The total aging test lasted more than 12 hours overnight, for a total of 25811 times a) All normal, no operational abnormalities
Response test after aging 1. Pull-on response: still within 5ms 2. Shut-off response: still around 8ms Conclusion 1. The response time is 2-3 times faster than the relay, and the relay can be directly replaced. 2. After high-intensity 12-hour aging, the performance is basically the same as before, stable and reliable, and can be used in ultra-long life occasions. 3. The driving power consumption is only 0.5mW, and the size of the power supply can be greatly reduced after replacement.
