Part Number: BQ77PL900 Hello support team,
Customer inquires if bq77PL900 has internal protection diode. Could you support?
*Protection diode between VCx and VCx-1, e.g. VC5 and VC4.
*Protection diode between VCx and GND
Thanks,

Part Number: BQ77PL900 Hello!
I have finished a basic schematic to implement the BQ77PL900 as a BMS with a 6S Li-ion battery. I have omitted some components because the size is important to this board, but I don't know if I'm wrong with something. …
Part Number: BQ77PL900 Dear Sir,
I have some questions for below.
could you please advise me about below list.
1. If there is a circuit for reference when separating FET of the charging / discharging as like below picture, could you let me know side…
Part Number: BQ77PL900 Hello Support team,
My customer inquires bq77PL900 behavior when VCx pin open. If VC10 pin on datasheet Fig.7 is open, how does bq77PL900 monitor cell voltage between VC9 and VC10? Does this see larger voltage than actual cell…
Part Number: BQ77PL900 Hi Team,
We have received an inquiry from a customer about the VOUT of BQ77PL900. According to customer, the input voltage for all channels of V(Cn-Cn+1) is the same but the output at VOUT varies. The test records are as follows.
…
Part Number: BQ77PL900 There is a caution in BQ77PL900 datasheet "the EV2300 provides 5V for the EEPROM signal when programming. If the board is configured for VLOG = 3.3V during programming, damaging voltages may be imposed on VREG2 and the I2C lines…
Part Number: BQ77PL900 Other Parts Discussed in Thread: BQ76940 , BQ78350-R1 Hello,
Customer wants to use BQ77PL900 for cell balancing and protection.
But customer's spec changed to 13S1P battery pack.
Can customer use two BQ77PL900 to protect and…
Part Number: BQ77PL900 We have designed a Cell balancing system with the reference of Evaluation board of BQ77PL900. I have programmed Bq77pl900 chip over voltage at 4.15 with 200mv hysteresis and under voltage at 2.9 with 400mv hysteresis. I have also…
Part Number: BQ77PL900 Hello everyone.
I used the BQ77PL900 battery charging and protection application. The BQ77PL900 is in host mode. The application is connected to the battery card bq77pl900 integrated. Balance orders and cell voltage monitoring is…
