Part Number: BQ24004 Other Parts Discussed in Thread: BQ24125 , BQ24130 , BQ24113A , BQ2057W , 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…
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…
Part Number: BQ25171-Q1 Other Parts Discussed in Thread: BQ24004 Hi team,
In the datasheet table 7-2, it is said that 11k ohm resistor is used to set 7.00V for 2 cell LiFePO4.
Can my customer use 11k ohm to set 7.00V for 2 cells Li-ion battery?

Part Number: BQ24005 Other Parts Discussed in Thread: BQ25171-Q1 , , BQ24004 Hello, I need to know how to simulate the 1Hz fault signal on the STAT1 pin. Can I subject the IC to an OVP event or heat the IC to trigger an die over temp? I need to ensure…
Hi Amy
Take a look at the BQ24004.
This is a dual cell charger that may work. It is optimized for higher current and is larger. The charge current and termination current accuracy need to be reviewed for your application. 12mA is a little low for…
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,

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.
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…
