Part Number: BQ24600 Hello TI team,
I have recently designed a 6S li-ion battery charger based on the BQ24600 design. There was a critical issue when the battery was being charged at the constant current stage where after give or take 3-4 minutes the…
Part Number: BQ24600 Hi everyone! I am working with BQ24600 and read datasheet (7.3.14 Temperature Qualification - page 14) and i don't know how to define RTHcold and RTHhot from t_cold and t_cut_off. Please help me! Thank a lot

Hi Larry,
Yes you can. As this is a buck charger, there is a certain threshold that input voltage needs to be maintained above output voltage for the part to switch. Please refer to the SLEEP threshold in the datasheet. After accounting for voltage…
Part Number: BQ24600 Other Parts Discussed in Thread: BQ24610 I cannot seem to get this chip to begin charging my 3S battery. I have attached the schematic and have written out key pin values.
VOUTBoost (our input into the BQ24600RVAR) - 14.7V with…
Part Number: BQ24600 If the battery voltage is become 0, we can not charge the battery. If we don't put Rt, thermistor , does it affect the charging or not?
Part Number: BQ24600 Other Parts Discussed in Thread: BQ24610 Hi Team,
Customer is using BQ24600 on their board for charging a Li-ion battery. They changed the battery chemistry to a lead acid battery. They're in the layout phase and don't wish to…
Part Number: BQ24600 Other Parts Discussed in Thread: , BQ77915 Dear TI support,
after some test, the low side MOSFET (Q6, see attached schematic) on the BQ24600 charger burns due to a shortcircuit. During this evet, only the battery was connected and…
Dear Jerry,
Is there any way you could capture the STAT and /PG pins? They are very useful for debugging the status of the charger.
In addition, can you please detail what thermistor is connected? In addition, what does the TS voltage look like alongside…
Part Number: BQ24600 Hello,
I have a battery charger based off the TI BQ24600 IC. the design is as per the reference design in the specification sheet. I have a 4S1P Li-Ion battery pack with a built in BMS.
schematic diagram attached for references…
Part Number: BQ24600 Hi,
I am using the BQ24600 IC and it is not correctly charging the battery. The circuit is designed to have an input voltage of 24V, an output voltage of 13.8V and a maximum output current of 5.3A. The 24V input is coming from a…
