BP2335 DIP

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.

The FT245RL is a USB to parallel FIFO interface with the following advanced features:-?Single chip USB to parallel FIFO bidirectional data transfer interface.Entire USB protocol handled on the chip.

The MCP2551 is a high-speed CAN. fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 device provides differential transmit and receive capability for the CAN protocol controller, and is fully compatible with the ISO-11898 standard, including 24V requirements.

Nearly any Liquid Crystal Display (LCD)1 with modest multiplex rates may be interfaced with the PCF85162 peripheral device. Any static or multiplexed LCD with up to four backplanes and up to 32 segments can have its driving signals generated by this device. For bigger LCD applications, it is simply cascaded. The two-line bidirectional I2 C-bus is used by the PCF85162 for communication with the majority of microcontrollers. A display RAM with auto-incremented addressing, hardware sub addressing, and display memory switching (static and duplex drive modes) all reduce communication overheads. Features LCD controller and driver on a single chip Selectable display bias configuration: static, 12, or 13; Internal LCD bias generation with voltage-follower buffers; Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing; 32 segment drives: Up to 8 14-segment alphanumeric characters, up to 16 7-segment numeric characters, and up to 128 components of any image For storing display data, use 32 bits of RAM. Flexible flashing modes; switching between display memory banks in static and duplex driving modes; and independent supply for LCD and logic voltage Broad power supply range: 1.8 to 5.5 volts
