AW9818E

AW9818E Jun. 2019 V1.1 AW9818E 77-Channel LED Driver with I2C Interface FEATURES GENERAL DESCRIPTION  77-channel LED or 21 RGB drivers AW9818E is a 77 channels LED driver with I2C  64-level currents setting and breathing interface support. AW9818E uses awinic distinctive individually for each LED  4-level IMAX selections: 10/20/30/40 mA  INTN pin interrupt output, low active  Compatible I2C Interface, VIO: 1.8V ~ 3.3V  I2C address: 0x3A/0x3B  Shutdown mode control: SHDN pin shutdown or software shutdown. Support register reset control and standby mode control  CLKIO pin can output internal OSC clock(4MHz)or select external input clock  TQFN4X4-28L package Free-FlashTM wisdom dimming technology, each LED can breathing individually with full autonomous l or half autonomous mode that reduces serial port communication load of main chipset maximally . a When one breathing complete in AW9818E, INTN pin will trigger an interrupt request. The function is i used to synchronize the LED breathing between t main chipset and AW9818E. 1.8V I2C interface of 400kHz fast mode is provided, n AW9818E supports SHDN pin shutdown or internal soft shutdown function. e AW9818E can configure to output the internal clock  Power supply: VDD (2.4V~3.3V) and VBAT (3.4V~5.5V). APPLICATIONS  Mobile phones and other hand-held devices  Gaming device (Keyboard, Mouse etc.) (4MHz) or external clock input. AW9818E supports cascading for synchronization of chips. d AW9818E is TQFN4X4-28L pac...
