Part Number: INA381-Q1 Other Parts Discussed in Thread: INA381 , UCC27524 , UCC27444 Hi,
The customer questions the INA381 simulation results.
The result is that when INA381A4 recognizes overcurrent, the Alert output is in Latch Mode, but it operates in…
Part Number: INA381-Q1 Hello TI,
I would like to use INA381-Q1 and I have a question regarding transition time for the RESET signal. Since the RESET pin is digital input, I would like to know minimum and maximum rise and fall times for the same. I have…
Hello,
Manoj Turpati said: Is it ok if i connect the Reset pin directly to 3.3V with a pull up to make it permanantly high to keep it in latch mode ?
Yes this will work fine, however if you cannot change the 3.3V you will have no way to turn off the alert…
Part Number: INA381-Q1 Other Parts Discussed in Thread: INA381 Hi Team,
May I know whether I can leverage all three INA381-Q1 and connect them to the same Rsense?
We will connect the VOUT pin to CMPIN pin in each INA381-Q1 and set the different threshold…
Part Number: INA381 Other Parts Discussed in Thread: INA303 , INA302 , INA300 1m ohm shunt is used to measure current. 2 INA381 ICs are used to measure bidirectional current in battery for charge (6A) and discharge (110A). When ever Surge is applied across…
Part Number: INA381-Q1 Hello,
1) Please specify the maximum leakage current for CMPREF pin considering junction temperature up to 125 °C.
2) Please specify the maximum leakage current into CMPIN pin when the hysteresis current source is not active, considering…
Hello Manoj,
Manoj Turpati said: I'm still not sure if you got my question regarding the maxium recommended voltage for CMPREF-Pin right. It seems to me the answer still refers only to the CMPIN-Pin and not the CMPREF-Pin. I understand that internally…
Part Number: INA381 Hi TI Teams,
From the datasheet of INA381, we know that its available gain is INA381A1(20V/V), INA381A2(50V/V), INA381A3(100V/V) and INA381A4(200V/V). Now the maximum current used in our project is a little more than 2A, how should…
Part Number: INA381 Other Parts Discussed in Thread: INA302 , INA303 Hello,
We are considering implementing the INA381 in a design and have two questions.
1) We are planning to use a large RC filter (1M + 2.2uF) between Vout and CMPIN to filter out load…
Part Number: INA381 Dear Team,
Our customer is applied this part in new proect.
it is going to mass produce for 8 years. Please check if you have a plan to discontinue this part.
Best regards,
