Part Number: TPS3895 Other Parts Discussed in Thread: TPS3808E Tool/software: Hi
Currently we found the electrical characteristic of TPS3895A is suitable for our application, but we need a package with SOT23, which is reworked easier than the USON pa…
Part Number: TPS3899 Other Parts Discussed in Thread: TPS3422 , TPS3808E , Hi
Customers reported that the TPS3899DL30DSER board cannot be turned on after calling it back, and RST# has no effect. Can you help identify the problem? Thanks
Hello,
The device is designed so that it will not be damaged when operating within the data sheet specs. Exposing the sense pin to voltage greater than VDD+0.3V may damage the device. There appears to be an internal diode as the input limit is VDD+0.3V…
Hello Joe, Thank you for your reply. Following is the circuit for the supervisor IC TPS3808E-Q1. The output of the current monitor IC can be connected to the sense pin. Following is the timing diagram of the supervisor IC TPS3808E-Q1
From the timing diagram…
Hi Mitesh,
Thank you for your question and thanks for pointing out this inquiry.
I checked with my team and the equation is correct, and that is a typo in the EC table.
You can also use TPS3808E datasheet since it is P2P with TPS3808.
I hope this helps…
Hello,
I would consider a new generation device such as TPS3808E or TPS3899.

Hi Brian,
Unfortunately 100pF is the smallest capacitor that the device could recognize.
Though we have the newest version of this device the TPS3808E. This device does have the same limitation of 100pF but the 1.25ms is calculated from 130pF and a 100pF…
