Part Number: LM3881 Hi team,
In datasheet of LM3881, there is the typical value of Tclk but no min and max value. Could you please share us min and max value?
Thanks.
Part Number: LM3881 Hello team,
The datasheet states that
"Considering the TADJ voltage threshold levels and the charge/discharge current magnitude, it can be shown that the timing capacitor-clock period relationship is typically 120 µs/nF …
Part Number: LM3881 The recommended behavior is to assert EN after powering the VCC. I'd like to confirm that if EN rise up to 0.55V without powering VCC, is there any problem?
Thanks.
Part Number: LM3881 Hello, I'm just working on a board redesgin for which I need a simple sequence to ramp up/down microprocessor power rails. The requirement is that the delay time of the sequence has to be only a few hunderd micro-seconds (best case…
Part Number: LM3881 Hi, team
Please tell me about the variation of TCLK. LM3881 can adjust TCLK by external capacitor CADJ. I think TCLK is affected by VHTH, VLTH, ITADJ_SRC, ITADJ_SINK as well as CADJ. ITADJ_SRC and ITADJ_SINK are equivalent including…
Part Number: LM3881 Hi Team，
My customer tested that when EN is pulled low, the low voltage level of Flag3 is 390mV. This is within the range of SPEC, but the customer wants to know why the low voltage level is as high as 300+mV, and how to reduce it. …
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
