Sorry, I shouldve explained in detail.
V1 is the power from USB charger.
Mcp73831 charging control IC controls the STAT pins depends on the charging process.
V2 voltage source is the STAT pin at MCP73831.
While charing, Vstat is 0.6v and when charged, Vstat becomes 4.7v.
Hello.
As you can see the attached files, two pins on LEDs are shorted to ground. It is PCB Soldering problem happened. It seems to destroy or fool the circuit.
While charging, Only Red LED lights on(this is expected result) and I did not want any current flow across R1 into ground(Blue line)...
Hi.
I am using the MCP73831 Battery charger for my design. I decided to add 2.7k ohm resistor at the PROG pin. So, I_reg is set to 370mA.
LTST-C195KG, dual color chip led is connected between the VDD and STAT pins for status indicator. The labeled "21" is the symbol for the battery.
Pin2 and 4...
Hi.
I
I ordered MCP73831/2 charging IC for my design and I would like to put charging indicator to android/ ios app. On the circuit, there are two LEDs to indicate the charging status( orange and green lights).
As you can see the attached file, there are few stages for charging battery...
