Additional supply input is provided so that the logic works at lower voltage. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be use for the connection of external sensing resistor. Two enabled inputs are provided to enable or disable the device independently of the input signals. It is a high voltage and high current full dual bridge driver designed to accept standard TTL logic level and drive inductive loads such as relays, solenoids and DC stepper motor. The l298 is an integrated monolithic circuit in a 15 lead multi-watt and power S020 package.
The L298 H Bridge is base on l298 Chip manufacture by ST Semiconductor.
