Part Number: BQ24004 Other Parts Discussed in Thread: BQ24125 , BQ24130 , BQ24113A , BQ24040 Dear Sir/Madam,
I plan to have two Lithium ion battery in serial so that I have a higher supply voltage to boost to 24V. Should I use battery charging controller…
Part Number: BQ24004 Dear Team,
I am looking for linear charger with package size < = 3 mmx 3mm for 2S Li bat in toy application.
May I know closest parts we have are BQ2400x series device?
Thank you.

Other Parts Discussed in Thread: BQ24004 Hello,
I'd like to use a bq24004 to charge a 2 cell series battery li-ion 8.4V, and power at the same time the rest of my circuit (a sensor 2mA of current, no problem about the voltage) from the battery. I have…
Hello, we are having the same trouble, our bq24004 doesn`t work. We have followed your datasheet and minimal configuration and schematics, using a maximun of 8,4V and we want 1A of charge ( Vsel:High, Rsense:0.1Ohm). We are supplying the battery with…
Hi Gaurav,
Sorry about the confusion. Below is what I found in the user guide . The red LED mentioned below is connected to the STAT1.
"The bq24004/5/6 enters preconditioning mode if the battery is below the LowV threshold. In this mode, the bq24004/5…
Hello
The BQ2057T is and older device with a large number of external parts. Can you change to another device?
A more integrated device to consider is the BQ24004, 05, or 06.
Part Number: BQ24005 Other Parts Discussed in Thread: BQ24004 , BQ24040 Hello,
The BQ24004/5/6 series support 2 series cells. is there an equivalent part for a 1-cell support?
Thank you,
Gaurav
Hello
The BQ2057W is a very old device with high external parts count, recommend looking at other devices.
A possible replacement device is the BQ24004, device has fewer external parts. Also the 0V condition will be precharge and provide up to 60mA.
Other Parts Discussed in Thread: BQ24004 Plsease help to suggest 2 Cell Li-ion charger solution, Fast charger is 230mA, Full charge judgment criterion is 12mA
