Part Number: TPS2553D Other Parts Discussed in Thread: TPS2553 , Hello team,
Let me ask a quick question. What is the difference of TPS2553D and TPS2553 in terms of the performance? I'd like to know if we need any care when we replace from TPS2553 to…
Part Number: TPS2553D Other Parts Discussed in Thread: TPS2553 We use TPS2335 for many years for USB power management.
Now I would like to use it as Super cap charger. At 250mA constant current charging looks fine, but at 500mA it is seems to go in…
Part Number: TPS2553D Hello,
Regarding to Reverse-Voltage protection on TPS2553D, my customer is asking a question.
(Question)
When input voltage is zero(no input) and output voltage is 5V , does Reverse-Voltage protection work correctly?
…
Part Number: TPS2553D Hi Team,
Could you help me regarding the question below?
(1). Is that no problem the EN pin is logic HIGH before the IN pin is risen up completely?
(2). Can the EN pin voltage be higher than the IN pin? (e.g. VIN=1.8V…
Part Number: TPS2553D Hi,
I have a question for current limit of TPS2553D.
If user set 500mA as current limit and system require over 500mA, will the device output 500mA? or it turn off internal FET due to over current protection?

Part Number: TPS2553D Other Parts Discussed in Thread: TPS2553 Hi Team,
My customer now would like to use TPS2553D to charge super capacitor.
when the charge current is lower than 400mA, TPS2553 is on, then current could flow into capacitor to charge…
Part Number: TPS2553D Hi,
I would like to know pin treatment.
1. FAULT pin : If user doesn't FAULT pin, should he keep the pin open?
2. EN pin : Can user connect VCC( IN pin) to EN without pull-up register? or should user set pull -up register?…
Part Number: TPS2553D Hi All:
I test the TPS2553D Reverse-Voltage funtion, the Vin is 5V.Then I use a DC/DC connect to Vout, the DC voltage is 5.5V~6V.I test the Vin again and the voltage is 5.5V,and FAULT PIN is still high.In the datasheet describtion…
Part Number: TPS2553D Hello team,
Would you mind telling me how to calculate the auto-retry time on this device?
According to the DS, it would be calculated by the external register(R_fault?) & capacitor(C_retry?).
Thank you,
Kazuki Kitaj…
Part Number: TPS2553 Hello,
Can you please confirm the following two statements?
TPS2553, TPS2553D and TPS2553-1 all have Reverse-Blocking function
The only difference between TPS2553 and TPS2553D is the operating temperature.
Thanks and best…
