Part Number: LP8764-Q1 Other Parts Discussed in Thread: TPS6594-Q1 Dear expert,
Customer system is TPS65941213+LP8764+TDA4.
They report 3pcs high temp shutdown issue among 15Ku manufacture boards.
At 85C air temp, TPS65941213-Q1 and LP8764-Q1 Tj is around…
Part Number: LP8764-Q1 I am trying to program the NVM of the above part. The chip is connected using I2C to an ARM chip. I have wrote a program that uses the BIN file from the GUI and writes the registers in the sequence that is defined in slvaf93a. I…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: LP87644Q1EVM I have a custom PCB that uses an LP876441B1RQKRQ1 and PIC to control it via I2C. The code has been tested with the LP87644Q1EVM and a PIC dev kit and there wasn't an issue enabling and…
Part Number: LP8764-Q1 We have a LP8764-Q1 based design. The GPIO4 is used as an enable input and there is no pull up selected for this input.
VCCA,PVIN_B1,PVIN_B2,PVIB_B3,PVIN_B4 = 5.0V
VIO = 3,.3V
We read VOUT_LDO = 1.8V
The actual design has 100K pullup…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: LP87563-Q1 Dear Team,
I have plan to use LP8764-Q1 part in my new design.I got some doubts on the current monitoring feature of LP8764-Q1.
In device datasheet section 8.7 output voltage monitor and…
Part Number: LP8764-Q1 Hi TI team,
I would like to check with you for the L inductance value buck 3 of LP8764-Q1.
You guys have recommended me typical value of 470pF, but could it be lower for 330nH?
As schematic figure below, I am going to change…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: TPS6594-Q1 We have an LP876441B1RQKRQ1 PMIC on our new design PCB which is not responding with data when we read the I2C.
We measured VCC=5.0V, VIO=3.3V, VOUT_LDO=1.8V, initially there was some residual…

Hi TI team,
I am facing UV problem for LP8764-Q1 on system reliability qualification. The fault report as following:
mfg-s32g> i2ctransfer -f -y 1 w1@0x20 0x5a r1
0x91
mfg-s32g> i2ctransfer -f -y 1 w1@0x20 0x5b r1
0x0…
Part Number: LP8764-Q1 We have an LP8764 part on our board, and we have programmed it with new config files several times with no issues. However, the last time we tried to re-program it, it always gives us error that "EEPROM Unlock Failed". My question…
Part Number: LP8764-Q1 Hi
We use the LP8764-Q1 on our automotive project. the condition is: 1. the RECOV_CNT_REG_2 (RECOV_CNT_THR) value is set to 0. 2. we turn the GENERAL_REG_1(REG_CRC_EN) to the "register CRC enable".
We use the Linux command…
