Hello Team,
We have been designing a CAR DASH CAM Product where we are going to implement - MP2723 for the batter Charging and managing the main power supply.
We have a 3.7V / 1000mAh Battery, which is used for the soft shutdown of device. We require a chipset which can provide output voltage = 3.55V to 4.4V and with 3A Current capacity.
While referring to the MPS profile we found the MP2723 which is capable for battery charging as well as managing the main power supply.
The Require quantity for MPQ4314 and MP2723 will be 5K / Annum.
With MP2723 we wanted to reconfirm the below points.
- At the time of first bootup, what is the chipset output behavior ?
-
Does it first charge the battery and then provide the output on Vsys ?
-
Does it do the battery charging and Vsys out at the same time ?
Our Requirement is - In any of the case when the device gets main power, it immediately provide Vsys and parallelly it charge the battery. (This scenario need to work in all condition whether the battery is available / deeply discharge / not available). The Vsys needs to above 3.6 voltage with at least 2A current.
-
There are below pins which we don’t want to use -
D+ , D-, OTG.
Can we keep then NC ? -
How to Commonly connect Analog Ground and Digital Ground ?
-
Please share reference deign Circuit
-
what value resistor to be set at ILIM to get the max output ?
