Part Number: LP8764-Q1 I am connected to a prototype board design with one LP876411 PMIC, using I2C. (The Scalable PMIC GUI is not working - another thread)
Reading and writing registers via I2C using python is possible. However, after a few days of trying…
Part Number: LP8764-Q1 I am using LP876411B4RQKRQ1 based design. I think I might have accidently enabled the LOCK bit to the EEPROM after the programming. How do I verify if the Lock bit is set for this device ? Which register to read and confirm ?
Th…
Part Number: LP8764-Q1 I use this part for several location on PCB. I found the difference of protection behavior when I tested OCP item.
So I'd like to check the fault event can be adjustable in configuration?
The current limits is set by 4.5A and…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: TPS6594-Q1 1- The default I2C address for the B4 part is 0x4C, before we configure it to a different I2C address in our system. Does B5 variant also have the same default I2C address?
2- What are…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: MSP-EXP432E401Y , UNIFLASH I am trying to configure a LP876411 PMIC, (The I2C interface is tested and can be used to read and write registers via a RPi)
The chip is not intuitive to program, so I am…
Part Number: LP8764-Q1 Under the application conditions of 3.3V input and 0.8V/20A output, the output capacitors of buck1-4 in TI reference design are all configured with 1210/47uF * 3. What is the reason for choosing such a large margin? Because if calculated…
Part Number: LP87561-Q1 Other Parts Discussed in Thread: LP8764-Q1 Hello, At LP87561-Q1, the SW_BX voltage could also exceed Absolute Maximum Ratings for short period like LP8764-Q1 as follows? If yes, how much voltage it could be within how much time…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: TPS6594-Q1 Hi,
I have enabled CRC for the LP8764 PMIC and also registers are locked using the REGISTER_LOCK Register (Offset = 0xA1)
To unlock the registers I am trying to write 0x9B to the same…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: LP87642Q1EVM I am using the LP87642Q1EVM. I have the WD_ERROR trigger taking the PFSM to a WD_ERROR state, where I am forcing nRSTOUT to be 1'b0. My intention is for an external processor to write…
Part Number: LP8764-Q1 The part is already programmed. The GPIO4 is configured as enable. Now when I try to re program the device, I keep GPIO4 = 1'b0. Still the programming takes an aweful lot of time. Now the device will not finish validation. The programming…
