I have searched the TI website for a while now and have not quite found a chip suitable for my application. It seems as though a one- or two-chip solution should exist; I'd like to ask for help in finding it. I have in mind a toy similar to the remote-control "Bitchar-G" miniature cars that were so popular a few years ago. This toy runs a small cell-phone vibrator motor and a small solenoid directly from a 1.2-1.5 volt rechargeable lithium battery. A voltage converter boosts the supply voltage to 3.0 V to run the radio receiver. I would like to use the boosted supply voltage to run an MSP430 device, giving the car a "brain". I would like a chip or FET array that will take CMOS level control signals and switch the direct battery current at the 1.2-1.5 V level to control the motor and solenoids. The SN754410 would look like a good solution, but requires a minimum supply voltage of 4.5 V. Do you have any suggestions? Sincerely, Bryan J. Lowder
Thanks to anybody who can help. -BJL
