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 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 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 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…
Part Number: BQ2000 Hi,
Customer is currently have a question about a bq2000sn-b5 chip, please see details below.
Customer currently using to recharge a NiMH battery pack of 13 cells of their product. The BAT+ connector connected to a voltage divider of 230k…
Part Number: BQ2000 When customers use tps54360dda, they find that VIN, SW and GND are short circuited together. What is the general reason for this?
There are two explanations for triggering PV function. Which of the following statements does the customer…
