Controller IC help
(OP)
Im looking for an IC that i can run off of 5V DC from a microcontroller to control the on/off of components that will be using 12-24V DC to operate. I was just going to use one transistor to control another transistor/scr but i know there are more "up-to-date" methods by using IC's. Can anyone suggest an IC to do this?
Thanks in advance
Thanks in advance

However, for the higher current the easiest way is to use a logic-level input N-channel MOSFET, and switch ground to the item. There are some available in dual surface-mount packages.
However, for external devices in some applications, ground switching is an unacceptable practice. Power switching is preferred which leads to an intermediate device to switch a P-channel MOSFET, or bootstrap supply arrangements still using an N-channel.
For 12 to 24 VDC, you might check for some semiconductor power devices designed for the automotive market.
