Question about output current on VDD for a BS2

Post by DestroyerX » Sat Feb 19, 2005 1:08 pm

I have another question regarding logic power.<p>For my project, I need 5v for logic voltage for a motor driver that requires 36mA, and also 5v to power my receiver that requires 19mA.<p>Do you think it would work if I hooked in both the logic voltage on the motor driver, and my receiver into VDD for power, or would they put too much stress on the BS2?<p>I tried looking on Parallax's website but couldn't find VDD's output current.<p>Thanks for your help,<p>Jason

From my rather old BS1/II manual...
"When the BS2 is active it draws approx 8mA. Since U4 [the 5v regulator] can provide up to 50mA the majority of its capacity is available for powering your custom circutry"<p>It sounds like you'd be pushing it.
"if it's not another it's one thing."
