LP8864S-Q1: Fault detection

Part Number: LP8864S-Q1

Hi team,

My customer want to know about open/short detection and OV, OT.

1. open/short detection

In my understanding, threshold is a LED output voltage not a current. And its voltage is represented in Fig.7-18.

According to datasheet, VLEDSHORT is 5.4V. However there are no value for VHEADROOM and VSHORTGND. Please teach me these value.

2. Overvoltage

They want to know why there are two OV detection(VFB_OVPL&VFB_OVPH). Please tell me reason and use case of this.

3. Overtemperature

If OT detected, user can read status by I2C?

Regards,

Youhei MIYAOKA
