RE: [AVR-Chat] avr & power semiconductors

2008-06-17 by Steven Hodge

I use IRF2804's to switch various current loads up to 50 A, using a Micrel
5014 (or 5015) driver.  The driver can be easily controlled with a signal
directly from the uC.    The control threshold is about 2 V.   The 2804's
have a really low on-resistance, only 2 milli-ohms, and I don't use any heat
sink at all up to 10 A or so.    At 50 A I use a modest heat sink, but have
yet to even feel it get warm.   They are spec'd up to 75 A continuous.
Pretty amazing little gizmos.
