Part Number: LM3880 Hello,
The LM3880 power sequencer mentions in the front-page of datasheet that it can be cascaded to three levels that control nine voltage rails. The datasheet does not show an example of this configuration. Is there any documentation…
Part Number: LM3880 The pspice model says it is using sequence designator 1, timing designator 1 parameters. Regardless of the sequence designator selected, per the datasheet, at power up the the sequence should always be Flag 1, Flag 2, Flag 3. Yet the…
Part Number: LM3880 Hi Team,
Can you please help provide the Delphi Thermal Model (or .pdml files) for this device? LM3880MF-1AD/NOPB
Thank you kindly,

Part Number: LM3880 Hi,
At the moment of signal output and power-on state, there will be two small voltage spikes. Attached are the design schematic and test waveform. Please help to check whether there is any problem with the design.
thank you!

Part Number: LM3880 When setting the EN terminal of the LM3880 by the resistance voltage divider method, the resistance voltage divider diagram on P6 of the data sheet shows input supply 2.7V to 5.5V, but considering VEN: min (1.0V) max (1.4V) If the…
Part Number: LM3880 Dear Support,
Please advise difference between part numbers LM3880MF-1AB/NOPB and LM3880MF-1AE/NOPB?
Kindly confirm also if the can be used interchangeably. Thanks
Part Number: LM3880 Hi,
I am currently using the LM3880 for power sequencing the gate and drain bias of a pHEMT amplifier. From what I read in the datasheet the EN pin will enable the chip if it is tied to GND, and will disable the chip when the pin…
Part Number: LM3880 Hi TI
In our development, we use LM3880MFE-1AE/NOPB to control 66AK2G12ABYA60, the circuit is below:
Recently we found a failure with LM3880, Failure phenomenon: When the PCAB is powered off at an interval of about 4s and then powered…
