Hi Dialog Team,
I would like to know the current consumption by DA14580 during:
1. Advertising (GAP)
2. Sleep (after advertising)
3. Advertising (for pairing)
4. Pairing.
I would like to know the various components that are switched ON/OFF during the conditions mentioned above.
What is the difference in the working of the various sensors(SPI/RTC) etc during advertising and during pairing???
先谢谢你，
山姆

Hi Sam,
are you looking for average power consumption or peak ? average also depends upoon advertising interval. Do you have either an expert or PRO kit ? It also depends upon SDK as latest SDK (3.0.8/3.0.10) has some power enhamcennts.
Peak current during RF Tx/Rx is also different to active current . The two sleep modes (extended adn sleep) are 1.2uA and 0..7uA typical.
The only way to measure true currents is to use a 6.5 digit DMM (to measure sub uA) . The exact average will depend upon advertising / connection intervals etc.. The Smart snippets power profiler tools is also very useful if oyu use the PRO or EXPERT kit to look at the average energy consumption where you can see the currents in the active/ tx&rx and sleep mode..

I want to know the peak current values. I have an expert kit. I am using SDK 3.0.6.
I want to calculate(theroretically) the maximum current consumed during advertising, pairing and sleep?
Current consumption during active mode and sleep mode?
DA14580芯片在广告期间的最大电流消耗是多少？进入休眠模式时会发生什么？
Thanking You,
Hi There, the best thing is to measure it . The peak is defined in teh datasheet... but the simplest way to look is to
(a) use a project (e.g. proximity) and the power profiler in smart snippets to actually measure the peak current on your expert board (use SPI/UART connection when you run smart-snippets to enable this)
(b) use a high precision 6.5 digit DMM to measure the uA level sleep current when it goes into extended or deep sleep.
在Tx或Rx活动（整个芯片，而不仅仅是收音机）期间，最大电流约为5mA，在长时间睡眠时，最大电流为1.2uA，在深度睡眠时小于1uA。

Hi,
我已经测量了电流值，但我想把理论上消耗的最大电流制成表格。DA14580在广告期间和配对时消耗的电流是多少？是5mA吗？
谢谢
Hi, the peak current is just under 5mA under any kind of radio activity : advertising events, connection events. Its only 5mA peak during RF activity - thats the same when its paired & connected or when its just advertising. The average current is depending upon the advertising interval / connection interval. When the device is active, but radio not in tx or rx, its few hundred uA... when its in sleep in teh 1.2uA / 0.7uA approx.. The average really depedns upon your application and how long you sleep / how frequently you wake to advertise / connect / move data. BR JE_Dialog
Hi Dialog Team,
(ACT_RX)_BOOST BAT ||| battery supply current ||| Typical application with boost converter and receiver active ||| Typ : 13.4 mA ||| Max : 16mA
In page 146 of DA14580 datasheet, the above statement is given. What does this mean? If the maximum peak current consumption by Dialog 14580 is less than 5mA, then what are the above values? I am really confused. Please help.
最大无线电电流为typically stated in BUCK mode - that is the battery current taken by the total device, in buck mode at 3V. If you using a boost converter, to boost up to 3V, then by physics your current is going to increase compared to buck. For example, in buck at 3V takes 5mA , then if you instead have a boost converter running from 1V (assume 100% efficiency), it will take 3x the current to delvier the current needed to the device (whicih runs at 3V).

我使用升压转换器将1.5V（电源）转换为1.8V。我的电池电流/Dialog消耗的电流是多少？
Hi,
I am using the Da14580 in boost mode. Does it damage the chip or DC-DC converter if I use 3V battery to power the chip in boost mode(VBAT1V pin)?
我还有一个关于DC-DC转换器的问题和附件。如果我在2V~2.35V的升压模式下给芯片供电，它能工作吗？从那以后效率如何？谢谢。
你好，梁云豪，
You are not going to damage the chip or the DCDC if you are operating over boost mode in 3V but the efficiency is going to be less than 50%.
在升压模式下的DCDC转换器，其特点不是你提到的电压范围，如图所示。
谢谢MT_dialog
Hi,
What is the efficiency about the voltage range from 2V to 2.35V? Thanks.
你好，梁云豪，
As mentioned above there is no efficinecy characterization when the DCDC converter operates over the voltage range that you mention as the picture that you ve attached indicates as well. Using the Buck configuration the device wont operate and in boost mode its not characterized since i trust that it will be worse than 70%.
