LV5231CS
Bi-CMOS IC
LED Driver
Overview
The LV5231CS is 16ch LED driver IC for the cell phones with built-in charge pump circuit.
Features
• 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 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.
