LV5231CS Datasheet | SANYO

.Data Sheet.co.kr Ordering number : ENA1970 Bi-CMOS IC 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 parator, 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 25.6m A) External current value control pin is provided. As for MLED6, a possible independent control (0.6 to 19.2m A) 3-color LEDs driver ×2 LED current can be switched indecently in 5-bit units (0.5 to 16m A) 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 32m A) RGBLED2 only LED driver for flash ×4 LED current can be switched indecently in 4-bit units (2 to 32m A) At the strobe mode (6 to 96m A) (FCTL: High) Flash mode 1sec limiter (It is an automatic migration in a normal mode after about 1sec at continuousness High of FCTL). As for FLED3 and FLED4, a possible independent control.
