Part Number: BQ7718 Tool/software: Hello,
We need to use a power MOSFET to block over-charge, but allow discharge.
To accomplish this, we need to disconnect the ground of the BQ7718 in fault condition.
Will this work? Or could it damage the IC? (schematic…
Part Number: BQ7718 Hi
The customer design with BQ7718, The 13 series lithium battery system uses three BQ771817DPJR chips, and their cascading method is 5+5+3.
Phenomenon ①: The output voltage of OVP2, OVP1, and OVP3 will be consumed by the triode, and…
Part Number: BQ7718 Hi team,
Does BQ7718 support random connection? I notice the abs voltage for each pin is 30V, from this aspect, this device can support that, but considering the secondary protection usually not a recoverable protection, so I am confused…
Part Number: BQ7718 Hi,
Based on the BQ7718 datasheet, the typical supply current is 1uA when cell voltage is 4V.
1) What is the IC supply current if the cell voltage is 3V/2.5V/2V?
2) What is the min IC supply current if cell voltage is 4V?
Please…
Part Number: BQ7718 Other Parts Discussed in Thread: BQ76952EVM , BQ77216 Hi Team,
According to the datasheet, the relationship between VDD and VOUT is shown below.
Then how to design the resistors below in BQ76952EVM if each BQ7718 has different number…
Part Number: BQ76952EVM Other Parts Discussed in Thread: BQ7718 Hello TI forum! My name's Pedro and I'm currently developing my own board using this chip. I noticed the EVM uses a secondary protection system composed by the BQ7718 overvoltage protection…
Part Number: BQ7718 The part we are thinking to use is: BQ771809DPJT.
We want to use this to charge 5 batteries and then switch to using these batteries in series to power a stepper motor. We are making a PCB and would like to know how to do the connections…
