TPS2552: Maximum allowed reverse current before MOSFET turns off

Kazuki Itoh

Part Number: TPS2552
Other Parts Discussed in Thread: TPS2553,

Hi team,

I have a question about TPS2552(D) and TPS2553(D).

Could you let me know the maximum allowed reverse current (VOUT-VIN/rds_on) before MOSFET turns off?

Please let me know the value which the device can endure 7ms (maximum MOSFET turn off time after applying the reverse voltage).

Best regards,

Itoh

Hi Itoh-san,

Sorry, I can not find this data from our design spec, let me ask our design engineer, maybe he will know it, I will let you know if I have any updates.

Hi Itoh-san,

I have a discussion with our design engineer, he told me that we may not can provide this data, because its maximum value depend on the continue time and different voltage, and we also can not simulate it.

HI Itoh-san,

Add one more point from our design engineer, don't worry about the device will be damage, actually the closed time is very smaller, and the power is very smaller too. Although we can not provide this data to you, but we don't meet the failure issue before. Thank you.

Best Regards,

Kuno
