Other Parts Discussed in Thread: BQ25120A Hello, I'm using the bq25120A on a printed board and when the battery is reaching a certain level of discharge, around 3.3 V and under, I have I2C communication problem, and the BQ become default value 1.8 V instead…
Part Number: BQ25120A Hi,
A quick clarifying question about BQ25120A operating modes. Table 10 in datasheet shows that VOVP is inactive during ship mode. Does this mean that there is no overvoltage protection and PMID would see whatever voltage is applied…
Part Number: BQ25120A Dear TI,
I am writing this email to complain about the BQ2520A., one of our products. And we used the BQ25120A device for battery charging and monitoring along with the battery gauge (BQ27425) IC. But We are facing a problem after a…
Part Number: BQ25120A Other Parts Discussed in Thread: BQ25120 Hello,
We are planning to use bq25120 A in our projects. To evaluate we purchased a bq25120 AEVM kit and did a load test. The load test configuration is as follows:
Buck converter (Vsys) -> 1.8V…
Part Number: BQ25120A Greetings,
I have a design based on the BQ25120A with an SD Card powered by the LDO output (3.0V). The system functions as expected when there is a battery attached (i.e. the LDO output is a stable 3.0V). However, when running the…

If VIN is present then it should still…
Part Number: BQ25120A Hi everyone,
All bq25120a function is working properly on our custom board. In fact we have been facing an issue about soldering bq25120a.
But bq25120a doesn't charge battery, even device supports buck and ldo output.
I have…
Part Number: BQ25120A Other Parts Discussed in Thread: BQ25121A Hi,
I'm using the BQ25120A and I need to change the output voltage value from 1.8V to 3.3V without using the software configuration. You will find below my schematic.
Best regards,

Part Number: BQ25120A Hi Team,
some question want to understard and learn from you:
1.When the battery voltage is 4.2V and the BQ25120A operates in ship mode, when the Vin input is 4.0V, the SYS of the BQ25120A will not output at this time, what is the…
