Looking for PWM chip recommendations

[dullard]

I need to take an analog 0-5V signal and get a 0%-100% PWM signal from that. It will be used to drive an H-bridge for a resistive load.

I thought I found the perfect solution with the TD340 from ST Microelectronics. Part with the circuit I need. But that appears to be obsolete. Before going down a huge wild-goose chase of other parts, I thought I'd come here. Does anyone know of a simple to use chip for this purpose?

Note: I'm self-taught, so I don't know too much about electronics.

If they do not have a comparable chip, then no one has it.

if they do have it, get it from this company

funny, just did a semester-long project in my EE class building an H-bridge for an R/C car. keep in mind that if you're driving a motor, it's also an inductive load...and the inductive spikes that I was getting in my project were about 120 Volts. use a capacitor across the motor and Schottky diodes across the mosfets. your ICs will need decoupling capacitors as well.

if you're using high-current mosfets, then you'll probably need mosfet drivers to switch them fast enough, because of the high gate capacitance.

as for the PWM conversion...another guy in the group programmed a PIC we had lying around in the lab.
