The NJW4303 is a 3-Phase Brushless DC Motor Control pre-driver IC with PWM control designed by New Japan Radio Co. Ltd. NJW4303 generates the most optimal current flow patterns by receiving rotor magnetic pole detection signals from hall elements of 3-phase brushless motor.
The MCP2200 is a USB-to-UART serial converter manufactured by Microchip and enables USB connectivity in applications that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256 bytes of integrated user EEPROM that is accessed for read/write operations via USB host commands.
The NS5S1153 integrated circuit is a DPDT (Double Pole Double Throw ) switch for combined true−ground audio and USB 2.0 high speed data applications. NS5S1153 allows portable systems to use a single port to pass either USB data or audio signals from an external headset. The switch is capable of passing signals with negative voltages as low as 2 V below ground.
