Part Number: LM3881 Hi,
We input 5.5V as both VIN and pull up voltage level at flag output for LM3881.
and we found the flag output will drop gradually after power up few minutes.
It will be normal again after power cycle.
The absolutly maximum Vin and…
Part Number: LM3881 Other Parts Discussed in Thread: LM3880 , Are there any plans to create a PSPICE for TI model for the LM3881? I would like to use this in my new design instead of the LM3880.
Thanks, Vernon
Part Number: LM3881 Hello support-team,
My customer inquires pull up resister value on FLAG pin. What is min recommended resister value? They would like to use 39kohm and pull up voltage is 3.3V.
Thanks,
Koji Ikeda
Part Number: LM3881 Other Parts Discussed in Thread: LM3880 Hi Support Team,
My customer is thinking about the pullup resistors of FLAG1, FLAG2 and FLAG3. The datasheet says that the resistors of 100 kOhm are recommended. They would like to reduce the…
Part Number: TPS23753A Other Parts Discussed in Thread: LM3881 , LM3880 I want to input the output (+5.0V DC) of the TPS23257A to the VCC pin of the LM3881 to satisfy the power supply rising sequence and power supply falling sequence.
We have already confirmed…
Part Number: LM3881 Hi Team,
My customer wants to use LM3881 to drive a IC, which needs a voltage threshold of 0.2V. If the low level max voltage is 0.4V, this will not work for the design. Is itpossible to drive the LM3881 low level max voltage less…

Part Number: LM3881 Hello team,
I understand that the recommended behavior is to assert EN after powering the VCC. But I'd like to confirm abnormal operation that is assert EN before VCC.
In the case of the assert EN before VCC, the LM3881 has a leak…
