Dual Full Bridge Driver

The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

Key Features

  • OPERATING SUPPLY VOLTAGE UP TO 46V
  • LOW SATURATION VOLTAGE
  • TOTAL DC CURRENT UP TO 4A
  • LOGICAL \"0\" INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY)
  • OVERTEMPERATURE PROTECTION
