Part Number: BQ77PL900 Hello,
I have two boards that I have adapted from the bq77pl900 EVM circuit for implementation in our system. The issue we are having is, the bq77pl900 chip becomes quite hot upon plugging in our 6S LiPo pack. There is no software…
Part Number: BQ77PL900 1. Not getting VREG1 and VREG2 for first time use until BMS charged once up to pack voltage.
2. In over voltage condition charging mosfet not getting OFF.
3. Some time resistor values are not showing proper values, like batteries…
Part Number: LM5171-Q1 Other Parts Discussed in Thread: LM5171 , , BQ77PL900 , BQ78PL114
The datasheet for the LM5171 Evaluation Module says 6 volts, but the LM5171-Q1 MOSFET chips say
Wide input voltage range: 2.7 V to 36 V
Programmable output voltage…
Part Number: BQ77PL900 Hello,
I am having trouble balancing a 6S LiPo battery using the bq77pl900 EVM. I was able to complete several charge cycles, but wanted to see evidence of the cell balancing algorithm taking over once the AFE gives an OV warning…
Part Number: BQ77PL900 Hi,
The customer has designed their own board with using BQ77PL900, which is very similar to the EVM in schematic design.
They try to program the EEPROM with using the GUI and EV2300. But, they get the errror on the GUI: "EEPROM…
Part Number: BQ77PL900 Other Parts Discussed in Thread: CC3200 , BQ76925 Hi,
I'm using cc3200 and Bq77pl900 interfaced with I2c when i'm reading the registers the sda line become low, i'm not getting from which side the sda line is becoming low.How do…
Part Number: BQ77PL900 Hi,
Trying to get a better understanding of the operation of the ZEDE pin the datasheet is a little light.
We need to delay the battery pack from providing power when plugged in (will have a gpio to enable pack) the short discription…
Part Number: BQ77PL900 Other Parts Discussed in Thread: CC3200 , BQ76925 Hi,
I'm using cc3200 LP and i have custom BQ77PL900 board and I want to use this board for monitoring the individual batteries. I don't have any Idea that how to start this board…
Part Number: BQ77PL900 Hi,
I'm using Bq77pl900 IC for checking the voltages of total pack and individual batteries.My questions are
1)If i want to measure the voltages i have to go into host control mode and measure the voltages through I2C and come…
Part Number: BQ77PL900 Hi,
my customer tested with our EVM.
By connecting 8 series 18650 battery cells to BAT pin, A. the LDO VREG1, VREG2 has no output, B. nor can they write to EEPROM.
By applying voltage only on PACK pin, there is LDO output and they…
