IPS2050H short circuit protection

Fredda · ‎2025-04-02

Can the IPS2050H withstand a full short circuit on the outputs?

Let's say the IPS2050H output is connected to a board power connector. What happens if:

1. The connector is first short circuited and then the IPS2050H is turned on.

2. The IPS2050H is already turned on and then the connector is short circuited.

Welcome @Fredda, to the community!

yes, the IPS2050H is protected against short circuits at its outputs, so that both cases would be covered. Please see the data sheet, section 7.3, and AN5784, section 3, for more details about the different possibilities.

Does it answer your question?

Thanks. Ok, that sounds good. I'm gonna get my hands on a STEVAL-IFP043V1 board and try it out.

Hi,

I've tested the IPS2050H short circuit protection with the STEVAL-IFP043V1 board and unfortunately it didn't go well.

Test setup according to below picture. IPD1 is connected to IN1 via 220 kohm resistor. Board powered with a 24V/15A PSU. The short circuit is introduced by inserting a connector with shortcircuited terminals. This resulted in a bang, a flash and a hole in the IC.
