• Nexperia Introduces New Automotive Grade Constant Current LED Driver Delivers 250mA Output Current

  

  Nexperia, the global leader in discrete devices, logic devices and MOSFET devices, has introduced its family of constant current LED drivers, which add eight new AEC-Q101 compliant devices. Low power and medium power LEDs with drive currents up to 250mA. The 16V NCR32xx and 40V NCR42xx series are available in two package styles: space-saving SOT457 (SC-74) and SOT223 (SC-73); the latter provides higher power capacity up to 1,250mW.

• About AT24C02 chip working principle

  

  The AT24C02 chip is an EEPROM device with an IIC interface. The so-called EEPROM is an electrically erasable programmable read only memory, which is a kind of ROM. It is a read-only memory, that is, power-down can continue to store data, while at the same time can be erased and rewritten under the action of ordinary voltage, which greatly facilitates the development of the single-chip microcomputer, and now many ROMs on the computer Is the EEPROM used.
