Part Number: BQ77908A Other Parts Discussed in Thread: BQ77915 , BQ76930 Please tell me the value of the input current of VCx pin of bq77908A. The data sheet of bq77908A did not contain the value of the input current of VCx pin.
Best regards, Kagawa
Other Parts Discussed in Thread: BQ77908A Hi TI Experts,
Per Table 3 in the datasheet, when the conditions for SCC (Short circuit charge) are met, then both the charge and discharge FETS will be turned off. We tested it and find that the charging current…
Other Parts Discussed in Thread: BQ77908A Dear TI Experts,
Assume the sense resistor interface to the bq77908a sees a pulsating current as shown in the attached image below. How will the safety IC interpret the voltage across the sense resistor?
Is the…
Other Parts Discussed in Thread: BQ77908A , BQ78350 , BQ76930 , BQ76940 Hello,
I want to use BQ77908A for battery protection. TI says the device is not recommended for new designs any longer. But BQ77908A would provide all features I'm looking for (protection…
Other Parts Discussed in Thread: BQ24618 , BQ77908A , BQ78350 , BQ34Z100 , BQ76930 Hello All,
I’m new to the battery sector and I want to design a battery management system for an RC-car. The car is powered from two LiPo batteries, one 6s and one 4s cells…
Other Parts Discussed in Thread: BQ77908A I want to preface this post with I have not worked with a charge controller before so there's a couple of questions in general as well as specifics about the chip.
The design I'm working on contains solar panels…
Other Parts Discussed in Thread: BQ34Z100 , BQ77908A On the bottom of page 28 in the datasheet of bq77908A there is a paragraph that to me seems to indicate that bq77908A can share its thermistor with another chip. Is this correct? In that case, does the…
Other Parts Discussed in Thread: BQ77908A I am trying to understand the voltages and power ratings associated with the external resistors that connect to the VC1-9 pins of the bq77908A. The data sheet says balancing current must be held to 50mA maximum…
Other Parts Discussed in Thread: BQ77908A , BQ24630 I am having an issue with a bq77908a. I am testing a design that is heavily based on the bq77908a EVM schematic but with a series FET configuration. There have been mistakes in copying from the EVM schematic…
Other Parts Discussed in Thread: BQ77908A We have an application for a bq77908A-protected pack that would use both maintenance (topping off the pack) and current taper limit (stop charge at 0.1C amps) chargers. Both charge and discharge protection FETs…
