Part Number: BQ24090 Tool/software: Dear Expert,
As we are trying to clear the inventory on hand, currently have a project with external charger which can charge up to 3 Litium Ion batteries at the same time.
I found we have a lot of inventory on BQ24090…
Part Number: BQ24090 Other Parts Discussed in Thread: BQ25185 , BQ24040 , BQ25180 Hi,
if you could suggest the Li-ion/PO single cell battery charges, with capacity of max current =1A, but settable to 500mA or less for USB based application
Input DC voltage…
Hello Abdurrahman,
The best protectors for a single cell in series (1s), would be the bq298x protector . This protector has high-side FET drivers to protect the battery, and it offers over-voltage, under-voltage, and current protections. I'd recommend…
Part Number: BQ24090 Hello,
My customer is using the BQ24090 for a wearable device.
They are looking for smaller package sizes and updated products for their next model.
If there is an optimal product among charging ICs with similar specifications and…
Part Number: BQ24090 Other Parts Discussed in Thread: BQ24316 Attached to this posting is a schematic of a single cell Li-Ion charger. The charger contains BQ24090 supervised by BQ24316. Why did the circuit designer include a 555 timer that zeroes out…

Dear TI Experts and Guru,
We have a bunch of questions here on thermal consideration of BQ24090. Please bear with me for a few minutes.
Q1: RθJA in thermal infomation and dissipation ratings of datasheet has two different…
Hey Yuanchen,
I apologize for the late reply.
Q1: Not quite sure about battery detection routine and how is it achieved. Why does BQ24090 think battery is present if VOUT< VREG-100mV? If battery is absent, isn't VOUT supposed to be detected as 0v initially…
Part Number: BQ24090 I want to know the thermal protection logic of this chip; and after the thermal test, the result is different from the spec; I want to get the phone call with the FAE, thanks.
Part Number: BQ24090 Dears,
If BQ24090 will go under SHORT PROTECTION status, when Vout down to 0.8v? Because i connect BQ24090 to Boost IC start working voltage lower than 0.8v, and find BQ24090 stop working.
And what means of Recovery ≥ V OUT(SC) …
Part Number: BQ24090 Other Parts Discussed in Thread: BQ24091 , BQ25887 , BQ24093 Hi,
We have used 1000's of BQ24090 without issue. On older PCBs, the device marking is 77 TI 24090. On the newer devices, it is 85 TI 24090.
With a large build of new…
