Part Number: TPS92620-Q1 Tool/software: Hi team,
Regarding the operation of LED Short-to-GND Detection, I think FAULT pin asserts low after red line in the figure below because VOUTx is still low. What do you think?
Best regards,
Shunsuke Yamamoto

Hi Matthew,
For two channel LED solutions, TPS92622-Q1 could be recommended with two PWM pins, and this device can support up to 150mA of output current per channel, but the input voltage needs to be paid more attention. If the current requirement is…
Part Number: LP8865Y-Q1 Other Parts Discussed in Thread: TPS92620-Q1 Hi Sir,
When the EN pin is pulled low, is the fault pin also pulled low at the same time?
Could you please share the parameter for the delay time of fault?
Hi Vishnu,
Sorry for the late reply.
For output current-150mA devices with 2 channels devices, it is recommended to use two-channels devices TPS92620-Q1(up to 250mA) or TPS92622-Q1(up to 150mA).
Based on the function of thermal sharing, Thermal performance…
