Other Parts Discussed in Thread: TPS3760
Please help us to assist our customer.
In the datasheet of the TPS38, it appears that it is designed to work with a supply voltage regardless of monitoring voltage and it is a perfect component to supervise the battery voltage (12 or 24 V) of a vehicle. Therefore, I would like to know your opinion about this device and if it is perfect for the objective that I have commented you.
The customer needs to use a device capable of monitoring a 24V DC supply voltage for developing an application that would work to this voltage, but it should continue to work during 10 ms (because the application has a secondary source capable to supply 24 V during 40 ms more and the application must execute specific tasks before shutting down) after of that happen a voltage break due to an interruption or the voltage reaching a value of 12 V or less. Therefore, when this situation occurs, the device must inform my application through a digital signal of "0" or "1" (3.3 V).
1) If you may, what other devices could you recommend to us that meet these features?
2) Could you provide us with a working example of the device you recommend?
Thank you in advance for your support.
