Hello All,
I'm looking for rugged >=100mA >=30V high side and low side switches
for an industrial (24V) controller, protected against short circuit
and overload and preferably also ESD/EFT.
I need two high side and two low side switches, any combination from
one integrated device to four separate switches would be o.k.
Switching speed is not that important - slow is good for EMI.
Control voltage is 5V or 3,3V logic level.
Four SOT223 (Infineon Profet, Hitfet etc.) or SO8 devices would be too
large. Maybe a dual SO8 low side switch and two SO8 high side switches
will work. Smaller cases or two SO8 would be great.
Any recommendations?
Please note that I currently don't trust in IRF since they
discontinued the IPS021L months ago without a replacement *) and
without notice on their web site. It' _still_ listed as available!
TIA,
Oliver
*) The recommended IPS1041L and IPS2041L are wimps compared to the
IPS021.
