74HC244 Octal Buffers And Line Driver IC
74HC244 Octal Buffer Line Driver IC (74244 IC) DIP-20 Package
The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs. The deviceĀ can be used as two 4-bit buffers or one 8-bit buffer. The device features two outputĀ enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOEĀ causes the outputs to assume a high impedance OFF-state. Inputs include clamp diodesĀ that enable the use of current limiting resistors to interface inputs to voltages in excess ofĀ VCC. 74hc244 datasheetBD6221F-E2
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.

BP3122
The BP3122 is a high precision primary-side feedback and regulation controller for LED lighting that functions in constant current control mode and is designed to work in inductor current discontinuous conduction mode, making it particularly ideal for fly back converters with universal input. The system's output power should be less than 5W.
The BP3122 contains a 650V power MOSFET. The secondary sensing and feedback circuit has been deleted since the adoption of main sense and feedback control technology. The looping compensatory components are likewise deleted while the overall operating conditions remain stable. It employs patent-pending source driver design and demagnetization detecting technology, has a very low operating current, and does not require an extra winding for measuring output current and powering the device. Because of the low component counts
Using the innovative high precise current sensing technology, the BP3122 achieves 5% LED current accuracy as well as good line and load control.
The BP3122 includes several protective features such as LED open/short circuit protection, CS resistor short circuit protection, over-temperature protection, and VCC under voltage protection.
