Part Number: BQ2000 Tool/software: Hello,
I want to build 10-s NI-MH battery charger at 2.5A fast charge. Is it possible to use bq2000 for this purpose? Only adjust Rsns according to Imax=0.05/Rsns ?
Thank you
Part Number: BQ2000 Tool/software: what is the real limitation for not using BQ2000 charger with more than 4 cells? Since the power controlled by the BQ2000 can be different from its Vin pin and the maximum charge voltage can be adjusted using a voltage…
Part Number: BQ2000 Hey team,
One of my customers is asking the below question. Let me know what you think
"I have another question regarding the battery charging IC BQ2000: For fast charging to be working the voltage on TS pin V_TS needs to be in a certain…
Part Number: BQ2000 We observed the charging current can vary as much as +/-10% from board to board. The resistor for current sensing is 1% 0.5ohm (for 500mA charging current). I checked the accuracy of each resistor used in the measurement and concluded…
Part Number: BQ2000 Hi sir,
How can I caculate the input voltage of BQ2000 for 3s NiMH application? Could it be lower than 7.5V? It can work only above 9.5V with the BQ2000EVM Even if I changed the Cf,Rf,and L1.
Thanks!
Part Number: BQ2000 Hi
I have a query with the Figure 12. of Using the bq2000/T to Control Fast Charge
What is purpose of D2, does it can remove?
Waiting for your reply.
Thanks

Part Number: BQ2000 Hello everyone,
I'm using the BQ2000 in a project. The IC should charge 2 NiMH battery while the device is connected to USB.
The device is controlled by a micro and the micro should be able to enable/disable the charge.
The device…
Part Number: BQ2000 Hello everyone,
I'm finding some issue on using BQ2000 while trying to charge 2 batteries Ni-Mh.
I started with the suggested schematics here below (pag.10 of the datasheet).
The only difference I use N-MOS instead of BJT for Q1…
Part Number: BQ2000 Hi Team,
I'm thinking of connecting a MOSFET to the MOD pin output and driving it, but would it be better to add a current limiting resistor to the gate? I want to be able to drive at a speed of about 500kHz.
There is no maximum…
Part Number: BQ2000 Hi team,
The customer has purchased this model of the BQ2000TSN-B5 IC and found that the printed word on the component body is Bq2000T, which is not consistent with TI's specification letter: 2000T. Could you help confirm whether the…
