The L298N is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a
high voltage, high current dual full-bridge driver designedto acceptstandardTTL logic levels anddrive
inductive loads such as relays, solenoids, DC and steppingmotors.
A dual full-bridge driver, also known as a dual H-bridge driver, is an integrated circuit (IC) or module designed to control and drive two separate full-bridge circuits. Each full-bridge typically consists of four switches (usually transistors or MOSFETs) configured in an H-bridge topology, which allows bidirectional control of a load, such as a motor or an actuator.
1. OPERATING SUPPLY VOLTAGE UP TO 46 V
2. TOTAL DC CURRENT UP TO 4 A
3. LOW SATURATION VOLTAGE
4. OVERTEMPERATURE PROTECTION
5. LOGICAL ”0” INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY) […]
Applications of dual full-bridge drivers include the control of DC motors, stepper motors, brushed and brushless DC motors, and actuators in various devices and systems, such as robotics, industrial automation, automotive applications, and consumer electronics.
