Yes, I can check this in the lab. I can provide you with typical values only (not guaranteed production test values).
I am working on an existing product using the ADM2587E chip. We are noticing in a new batch of boards that the chip sometimes takes more current to turn on - specifically as the input voltage on the chip is increased from 2.0V to 5.0V the current consumption peaks around 2.6 to 2.8 V in the 31 mA range. It is interesting to watch the sudden current drop as you cross the ~2.85V threshold for the chip - current almost drops in half from about 31mA to about 15 mA.
We have a current limited supply due to how we are using the chip and this is causing us problems with about 1 in 40 units. We have 10uF on input and output and a current limit of 40 mA for the input power. We have attempted to reduce that amount but for all units this does not work, even when the input and output capacitance on the chip is reduced to 0.2uF sometimes they will try to draw more current than our board allows. We do realize this non standard way of using the chips is probably not the greatest practice.
Does anyone have experience with startup current variation between these chips lot to lot or chip to chip or is anyone aware of a minimum startup current requirement for these chips over voltage.
These are typical lab measurements, at +25C:
At 3.3 V Vcc: the Icc is about 15mA for a 76.5 kbps data rate.
At 5.0 V Vcc: the Icc is about 13mA for a 76.5 kbps data rate.
This is for your requested condition DE = /RE = 0 V
I look forward to a result
Hi,I want to know ADM2587E Power consumption when I receive data
Condition： DE is tied to 0V (disabled), and !RE is tied to 0V (enabled).、Data Rate ≤ 500 kbps （I hope 76.5Kbps)
Would you tell me the consumption electric current?
Furthermore, would you tell me maximum , too?
(It is not a guarantee, the reference level is all right）
