UPD16808 Description
The µPD16808 is a monolithic dual H bridge driver circuit which employing N-channel power MOS FETs for its driver stage. By using the power MOS FETs for the output stage, saturation voltage and power consumption are substantially improved as pared with conventional driver circuits that use bipolar transistors. Because the dual H bridge driver circuits at the output stage are independent of each other, this IC is...
