Part Number: BQ2057W Hi,
I would like to ask you about the BQ2057W device. For the flowchart in Fig. 2 of the data sheet, is "Yes" indicated by the red circle in the attached figure correct "No"?
Best regards,
Part Number: BQ2057W Other Parts Discussed in Thread: BQ2057 Good morning everybody,
I'm using the BQ2057WSN in a project in order to recharge a 2S1P battery pack. The power supply that I use to recharge the battery as 12V output, with 4.5A max.
The…
Part Number: BQ2057W Hi team, Could you tell me the ESD value for BQ2057W? It was not mentioned in the datasheet. Is there a place where I should install a barista? Sincerely. Kengo.
Part Number: BQ2057W Hi,
I would like to ask you a question about the BQ2057WTS device.
(Question 1) In the figure below, should the minimum VCC voltage when VBAT is 8.4V be as follows? The diode (D1) is not considered. VCC = VBAT-VDS (Q1) - (RSNS…
Part Number: BQ2057W Hi TI expert,
Could you please analysis the details of two issue points in the device diagram:
1. How does the DONE signal (low effective) stop the charge process?
2. How can output CC pin with a P-channel MOSFET turn on and…
Part Number: BQ2057W Other Parts Discussed in Thread: BQ2057 ,
I must be missing something with this calculation because I can't get the same results
R(SNS) = V(SNS) / I(O(REG))
In the example R(SNS) = .2 Ohms and I(O(REG)) = .5 A. This…
Part Number: BQ2057W Other Parts Discussed in Thread: BQ2057 Hi TI expert,
External pass-transistor of BQ2057W can be Transistor or MOSFET, right? What's the difference of these two kinds solution? What's the key spec need to pay attention in selection…
Part Number: BQ2057W Other Parts Discussed in Thread: BQ24005 , Or testing has shown a massive inrush of current when charging our batteries from cutoff voltages. This is not what the data sheet says should happen (Diagram 2). What are some possible causes…
Part Number: BQ2057W Hi team, Could you tell me about the Absolute maximum voltage for BAT pin? Is the battery voltage not visible on the BAT pin when VCC = 0V with the datasheet connection method? BATpin's absolute maximum voltage is VCC+0.3V. Sincerely…
