I’m using a couple of the Sanyo LB1836M h-bridge chips in a robot I’m building. I’ve looked through the data sheet, but can’t see anywhere what the max PWM frequency is for this chip.
What frequency did you use in the serial board that uses this chip?
The main PCB is 4" long and 1" wide, and I have to fit an ATmega168, two dual-motor driver chips, a 3-axis compass chip (Honeywell HMC6343), plugs for the motors, a pair of hall effect sensors, an interface plug to a depth sensor, a programming header, and so on.
Thanks for the SOIC note. I’m pretty sure I remember that package being referred to as a type of SOIC before, and it we had already mentioned the 1mm pitch, but I changed the page to use the MFP14S name that Sanyo is calling it now.
