h-bridge and IR help

Posts: 46,084
okay I have two totally different questions here.
1. Does anyone know of some kind of h-bridge on a small IC(8 pins or so).
Basically what I need is a half 1293d. I want to save some space on my
bot's circuit board. I need it to drive 1 motor so why would I use a double
h-bridge? Or does anyone know of some small power mosfets in a T0-92
package that I could use to build an h-bridge? my motor will probably draw
no more that 200 ma when stalled.
2. I've gotta cram a couple more IR sensors on my bot. Is it possible to
use one low-pass filter for 2 modules. that is 2 modules will use the same
47ohm resitor, and the same 47uF cap.
