LV5231CS

www.DataSheet.co.kr Ordering number : ENA1970 Bi-CMOS IC LV5231CS Overview Features LED Driver The LV5231CS is 16ch LED driver IC for the cell phones with built-in charge pump circuit. LED driver ×16 (3-color ×2, MAIN, Flash) and on-chip switching regulator control circuit. Each LED driver current level can be adjusted independently over the serial bus. Support strobe mode of LED for flash. Gradation function (3-color LEDs) Ring tone signal and 3-color LEDs synchronization function. Miniature package Function PWM switching regulator control circuit Built-in Triangular wave oscillator, Standard voltage, PWM comparator, Driver, DTC and short-circuit protection circuit. The output interception circuit at the overload is a timer latch method. LED driver LED driver for the main liquid crystal backlight ×6 LED current can be switched indecently in 6-bit units (0.4 to 25.6mA) External current value control pin is provided. As for MLED6, a possible independent control (0.6 to 19.2mA) 3-colorLEDs driver ×2 LED current can be switched indecently in 5-bit units (0.5 to 16mA) Ring tone synchronization function (forced activation with SCTL: High) It corresponds to the information mode. RGBLED1 only, Built-in low current consumption internal oscillator Gradation function Twice current mode (1 to 32mA) RGBLED2 only LED driver for flash ×4 LED current can be switched indecently in 4-bit units (2 to 32mA) At the strobe mode (6 to 96mA) (FCTL: High) Flash mode 1sec limite...
