Sign up using Facebook. As is stated in the below table the output max current is 35mA for each output, being the nominal current 20mA, enough to control a LED in every output. My belief is that turning on all 8 outputs at 20 ma exceeds the IC max current. Glad to know i’m not going nuts.

Maybe you will be OK afterall, or maybe a simple part change can fix everything up. The load is between the IC and ground source current? However, driving a LED at 20 mA is often unnecessary today.

My understanding is that is has a max of 35 mA per pin, but a total of 70 mA for the Datasheett. There is a ready made solution and the supplier insists it will be OK but having read the data sheet I don’t think it will.

My solution is to use P channel mosfets to switch the power. I should have added that there are 2 LEDS being driven from each output.

Email Required, datasheeet never shown. You are not wrong. Nik Middleton 6 5. Hi, basic schematic added. The IC has a global limit of 70 mA.

Data sheet is here: Home Questions Tags Users Unanswered. Get on to your supplier and ask them to justify their thoughts. Post as a guest Name. Would really appreciate some input.

I’m loosing some voltage 4. A simple indicator LED will be fine at 5 mA. Sign up or log in Sign up using Google.

I’ve been reading datashee lot of data sheets of late looking for chips that will work for a small project. It would have been so simple to use a current drain driver but sadly it’s not an option. You can edit your question and then click on the icon that looks like a schematic symbol, and it will load the schematic editor.
