I am looking to test an embedded system for its behavior during power interruption soon after power on. The system is supplied with 15V DC power with a steady state draw of <
The power transient is shown below -
1ms off, and then on again for steady state, simulating the action of a specific mechanical interrupter to turn the device on. The turn-off and turn-on time is <
10us . When the power is turned off the supply line is left floating
Mechanical relays are not quick enough to do this, I have considered solid state relays but their behavior is load dependent. Programmable Power supplies are usually with a resolution no better than
Since the total load is under
1A peak I have considered using a Power MOSFET as the switching device and this is my current approach.
Is there anything else that you can suggest to test these conditions in a controlled, repeatable manner?
