Part Number: BQ2000T Other Parts Discussed in Thread: BQ2003 I am searching for a completely alternative component to replace the end of life one, BQ2000T. This IC component is a buck switch charger controller. how to understand the Fast-charge charging…
Part Number: BQ2000T I want to run my BQ2000T charger from a computer USB port. What are the design changes I need to make compared to the switching controller shown in the schematic in the BQ2000T data sheet? This circuit only runs down to 10V. I understand…
Part Number: BQ2000T Is the BQ2000T compatible with USB charging ports? Is there a recommend procedure for interfacing this device with USB charging ports. I will be using an FTDI USB to serial device FT230SX.
Thank you,
DIck
Part Number: BQ2000T Using the BQ2000T to charge either 4 cells NiHM or 4 cells Lithium, is there an indication from the device that the batteries are inserted or not?
Thanks,

Part Number: BQ2000T Other Parts Discussed in Thread: BQ2000 Can the BQ2000T series chargers be used to safely charge the newly available AA size Lithium cells that have a 1.5V integrated regulator inside the cell? If so, what are your recommendations…
Part Number: BQ2000T Hello,
- We're using a bq2000T-based circuit to charge a 1600 mAh 3-series-cell NiMH battery pack. I've attached a schematic. Not that it matters, but in case anyone asks, the input power BAT_BOOST is from a 6 V boost converter…
Hi Kedar,
Regarding following comment, it seems bq2000T has 20% variation from 1000mA(800mA to 1200mA).
Do you have any variation data for it?
4) IMAX depends on VSNS voltage of 50mV (this is where numerator of 0.05 is obtained). Once voltage sensed…
Part Number: BQ2000T Other Parts Discussed in Thread: BQ2000 , BQ2000EVM Hello,
In the document "Using the bq2000/T to Control Fast Charge" there is a formula on page 4 for maximum switching frequency: Rf * Cf = 1 / (4 * F). When I look at the…
Part Number: BQ2000T Hello,
We have based our bq2000T design on the attached reference schematic. I've also attached an image of our schematic. The problem we're seeing is that charger turns on the LED (/LED low) even when there is no external charger…
Part Number: BQ2000T Hello folks. Into the BQ2000T datasheet ( http://www.ti.com/lit/ds/symlink/bq2000t.pdf ), inside 'Charge Current Control' section, in page 11, it is said:
"A hysteresis capacitor (CHYS) is required between the CMOD pin and…
