Part Number: BQ25122 Other Parts Discussed in Thread: BQ25180 , BQ25150 Hi TI! Do you have a proposed alternative to the BQ25122 without the mandatory 1V2 buck converter and still with features such as HOT/COLD behaviour, battery voltage monitoring, VinDPM…
Part Number: BQ25122 Hi all,
According to the datsheet, the charge safety timer has programmable range. How do we configure it? I didin't see any I2C registers for this.
Thanks

Part Number: BQ25122 Hi,
I am using a BQ25122 to charge a VARTA CP1240A3 battery (Li-ION, 3.7V - 0,2Wh).
I connected a 4,99K resistor to Riset (40mA Icharge)
I connected a 1K resistor to RLim(200mA Ilimit)
I connected a 4,99K resistor to Rtterm (4mA Iprecharge…
Part Number: BQ25122 Hi all,
In case of using the BQ25122 in stand alone mode, If i connect ILIM, ISET and IPRETERM to GND, what will be charge current and the input current limit?
what about the precharge current, what will be the % of ISET?
Thanks

Hi Lasse,
Thank you for your patience in this matter. As an update, I've been able to discuss with the Failure Mode champion this week. A Failure Mode Distribution analysis is typically reserved for our Functional Safety qualified parts as it requires…
Part Number: BQ25122 Other Parts Discussed in Thread: BQ25120 Hi there!
We are trying to monitor VBAT on the go while charging, but I seem to have difficulties triggering a new measurement by writing a 0x0b10000000 to BQ25120_BATT_VOLT_MONITOR_REG.
It seems…

Hi Experts,
Good day. We have this case from client.
According to the datasheet, voltage input can be from 3.4V to 5.5V. However, on the board we designed, voltage input min is 4.9V to enable the charge. Why is it not possible for…
Part Number: BQ25122 Hi everyone, I have a question regarding charge enable on BQ25122 charger IC. Is there a possibility to enable battery charging while /CD(chip disable) pin is at high voltage level(active battery mode)? Thanks in advance! Kind Regards…
