L6203 Bridge Driver: Circuit, Pinout, and Datasheet

L6203 is a full-control bridge driver chip that uses multi-source BCD (Bipolar, CMOS, DMOS) technology to control the motor. This chip can integrate independent DMOS field-effect transistors, CMOS and diodes on one chip. Due to the use of modular expansion technology,  L6203 can realize logic circuit and power stage optimization, it has been possible to optimize the logic circuitry and the power stage to achieve the best possible performance. 

The DMOS field-effect tube can operate at a voltage of 42V and has high efficiency and high-speed switching performance. Compatible with all TTL, CMOS and μC inputs. Each independent logic input can control one channel (half-bridge), and the common enable terminal can control two channels. The I.C. is mounted in three different packages.
