Part Number: BQ24052 Other Parts Discussed in Thread: BQ24050 , , BQ25170 , BQ25171-Q1 , BQ24040 Specs would be single cell, 1A charge current, li-polymer chemistry, linear topology, also needs 5V Vin capability from USB port.
Also what's the difference…
Part Number: BQ24052 Hallo,
I have a design in which the D+ and D- pins of BQ24052 are floating. The device is powered through the micro USB port of an adaptor. Is it possible to charge the battery with 500 mA or is it limited to 100 mA when the data…
Yes, the bq24052 can just power the system without a battery being installed. This is called TTDM and is explained on page 24 of the datasheet.
The ISET2 pin has 3 different states--high, low, and floating. Each of these states gives a different charge…
The part has a short circuit mode under 1V on the output and this is where one gets the 15mA. It should bet the precharge current between ~1V and 2.5V.
Adjusting the precharge pot to 10k should give 100% of fast charge. With a 1k it should have 75mV…
There are posts on here saying it's NRND? https://e2e.ti.com/support/power-management/f/196/t/557805 https://e2e.ti.com/support/power-management/f/196/t/571330
But https://www.ti.com/product/BQ24050 is the datasheet for BQ24055 and it says "Active…
Other Parts Discussed in Thread: BQ24052 Hello
Charge current of BQ24052 is 10mA ~ 1.0A. If customer request 15mA ~ 1.5A to charge current, has any suitable solution to meet? Thank you.

hi Tim,
unforutnately there will be no drop replacement...
the BQ24055 has only 2 pins more than the same family products BQ24050 and BQ24052...
one of these pins is power good, the other one is not used, so ...
I understand could be annoying to re-spin…
Other Parts Discussed in Thread: BQ24050 , BQ24052 , BQ24040 - Which is the best of this family from cost, availability point of view - ISET2 we are tying to GND. We are not using USB power. OK ? - D+ and D- are left floating. OK ? - When input power to the…
Part Number: BQ24052EVM Hi.
I testing with BQ24052EVM.
Case 1 : Vin 5V and Discharge 2A to load
==> Charging and Discharging is OK
Case 2 : Vin 5V and Discharge 2.5A to load
==> Charging is OK.
==> But When Vin is removed, Vin voltage is about…
Other Parts Discussed in Thread: BQ24050 , BQ24052 , BQ24040 Hello,
following the application note of the bq24050, bq24052, bq24055 (SLUS940C –SEPTEMBER 2009–REVISED DECEMBER 2014), I made a charger for single lithium cell, with a resistor of 1K between…
