LP5523: RGB LED driver LP5523 time interval

Part Number: LP5523


 Dear All,

目前在尋找 2nd 替代的LED driver

看LP5523 的datasheet, register 02~05 ,16~ 1E 是可以控制 個別輸出 跟PWM ,怕有誤解,

 

確認一下 底下的問題,

 

Q1.是否每個output(D1~D9)可以各別獨立控制brightness跟blinking的間隔?

Ex: D1 =3mA , D2=2mA ,D3=1mA , D4=0.5mA ..etc

LED1-3 需要0.5秒亮0.5秒暗

LED4-6 需要1秒亮1秒暗

LED7-9 需要1秒亮2秒暗

 

Q2.設定的輸出電流 在blinking會不會受到影響?

Q3. 需要HOST給CLK /PWM , 還是內部可以自產?

Q4. Output(D1~9) 可以切換成 SINK mode 嗎?
