74HC244 Octal Buffers And Line Driver IC

Basic Information Full bridge drivers, or H-bridges, are what are used in brush motor applications. Each IC has an operating voltage range of 6V to 15V and a maximum output current of 2A. The output stage's MOS transistors enable PWM speed control. Motor driver ICs that have been discontinued can be directly replaced thanks to the inbuilt VREF voltage control mechanism. Low-power consumption designs are made possible by these incredibly efficient H-bridge driver ICs. Features Built-in Selectable Features Cross-Conduction Prevention Circuit, OCP, OVP, TSD, and UVLO Protection Circuits, One Channel or Two Channels Configuration, VREF Voltage Setting Pin Enables PWM Duty Control, and One or Two Channels Configuration.   Key Particulars Maximum Output Current: 0.5A, 1.0A, 2.0A; Output ON-Resistance: 1.5; PWM Input Frequency Range: 20kHz to 100kHz; Standby Current: 0A; Supply Voltage Range: 18V(Max); (Typ) -40?C to 85?C is the operating temperature range. Applications VTR, CD/DVD players, audiovisual gear, optical disc drives, PC add-ons, and OA equipment

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.

The SG3525A pulse width modulator control circuit offers improved performance and lower external parts count when implemented for controlling all types of switching power supplies.
