LP8867C-Q1: Difference between LP8867C-Q1 and LP8867-Q1

Part Number: LP8867C-Q1
Other Parts Discussed in Thread: LP8867-Q1

Hi team,

Do you have comparison table between LP8867-Q1 and LP8867C-Q1 in aspect of pin location, pin function, electrical characteristics, and internal chip, wire bonding differences?

I am proposing LP8867C-Q1 for replacement from LP8867-Q1 and we need these differences. I should note that datasheet's "5 Device Comparison Table" is not enough because it does not include each pin location, electrical characteristics, and internal chip, wire bonding differences.

Regards,
Ochi

Hi, Ochi,

Difference between LP8867C and LP8867 are PIN 8, PIN 19 AND PIN 20.

LP8867C removed (1). LED current derating feature with external NTC (pin8). (2). Power line FET control(pin19 and pin 20) for lower cost. Others are the same.

Regards,

X.G

Hi Xiaoguang,

Thank you. The reason why "Others are the same" you mentioned is using the same chip for both of LP8867-Q1 and LP8867C-Q1? If your answer for this question includes confidential information, please email to me internally.

Regards,
Ochi

Hi, Ochi,

LP8867C-Q1 is the low cost version of LP8867. Thus, it spins from LP8867 and removes feature mentioned above.

XG.
