The L298 from ST is an integrated high voltage, high current Dual Full-Bridge Driver. The device is designed to accept standard TTL logic and drive inductive loads in Relays, Solenoids, DC and Stepper Motors. Featured are two enable inputs that allow the L298 to be enabled or disabled independently of the input signals. The emitters of the lower transistors of each bridge are connected and the corresponding external terminal can be used to connect an external sensing resistor. In addition, a supply input is provided so that the logic works at a lower voltage.

Features:

Operating supply voltage up to 46 V
Total DC current of up to 4 A
Low saturation voltage
Over-temperature protection
Logical “0” input voltage up to 1.5 V (high noise immunity)
