Hello Max, For a 2S battery protector with overvoltage protection and undervoltage protection, we have these options: 1. BQ77307 ( BQ77307 data sheet, product information and support | TI.com ) 2. BQ76905 ( BQ76905 data sheet, product information and…
Hello Kailun, I think the best 2S protector for the specifications you've listed is our BQ77307 .
Something to keep in mind, the user can program the settings they desire with an MCU; however, it will reset to the default configuration if the device…
Hi Luis,
Thanks for your response. I have removed the 100E resistors (SRN & SRP) from current sense resistors.
Can I use BQ77307 without MCU and for 300AH Battery.
How to disable UV in this IC and can you please share any reference circuit?
Thanks…
Hello Cho,
The R53 resistor should be between the gate-source of Q5/Q7
Else, it seems that it is copying the EVM schematic. Was there any other change from the schematic?
Is there a reason this device was chosen? There are much newer protector…
