LV5223GR
Bi-CMOS IC
LED Driver
Overview
The LV5223GR is 9ch LED driver IC for the cell phones with built-in charge pump circuit.
Features
• LED driver ×9 channels (3-color 1, 3-color 2, GPO (LED) ×3, 9 channels in total) and on-chip charge pump circuit.
• Each LED driver current level can be adjusted independently over the serial bus.
• Ring tone and 3-color LEDs (3-color 1, 3-color 2) synchronization function.
• Gradation function (3-color 1, 3-color 2, in total 6 channels only)
• RLED2 and GLED2 support strobe mode.
• Miniature package
Function
• Charge pump circuit ((2 times step up) Output voltage: 5V)
• LED driver 3-color LED ×2 + GPO (LED) LED driver ×3
Channel 1 LED current can be switched indecently in 5-bit units (0.5 to 16mA)
Ring tone synchronization function (forced activation with SCTL: H)

Pin function
GND pin1 for LED driver
LED driver pin for RGB1 and RGB2.
Feedback is applied so that the current flowing to the output
transistor becomes the set current level. When RT=27kΩ, the
driver output current levels can be independently adjusted from
approx. 0.5mA to 16mA in 0.5mA steps by serial setting. In the
strobe mode, the current levels can be independently adjusted
from 2.8mA to 44.8mA in 2.8mA steps for the RLED2 and GLED2
pins only.
GND pin2 for LED driver
GPO output/LED driver shared pin. Output can be set to current
sink by serial setting or VDD or GND voltage can be output.
Equivalent Circuit
VDD
11 RT
12 SDA
Reference current setting resistor connection pin. The reference
current is generated by connecting an external resistor to GND.
The pin voltage is approximately 0.65V. By changing this current
level, the oscillation frequency and LED driver current (3-color 1
and 3-color 2 only) can be changed.
