Part Number: LP87745-Q1 Tool/software: At present, we are using the Pmic chip LP877451 in our development process. Could you please provide the relevant sample code?
Part Number: LP87745-Q1 Tool/software: LP87745-Q1 will let the RSTOUT output low every 4.9s and shut the power down every about 70s after turning on .We already give the SPI-cs low voltage below 0.1v to desable the watchdog but RST will still output low…

Hello guys,
One of my customers is considering using LP87745-Q1 as AM2732(Sitara) power supply because LP87745 is used on AM2732 EVM.
At this moment, they have the following…
Part Number: LP87745-Q1 Tool/software: We would like to share an observation related to the PMIC behavior during a long startup issue in the SBL (Secondary Boot Loader) phase.
During SBL startup, we read specific PMIC registers to retrieve error information…
Part Number: LP87745-Q1 Tool/software: Hi,
May I ask why does the 1V output disconnect for 4ms every approximately 74 seconds when a 2.2k pull-down resistor is already connected to the WD pin.
Part Number: LP87745-Q1 Tool/software: Hi, TI team
Now we want to compare the difference of OTP configuration information between the LP877451A1RXVRQ1 and LP877451A4RXVRQ1. Currently we have the OTP config file of LP877451A4RXVRQ1, but the LP877451A1RXVRQ1…
Part Number: LP87745-Q1 Tool/software: Hi TI Team
I used the LM63625 and LP877451 to power the forward radar. Currently, for the functional safety analysis, the safety manuals of these two chips as well as the documents that are helpful for the analysis…
Part Number: LP87745-Q1 Tool/software: Hello,
I'm working with LP87745-Q1 PMIC.
I want to use the watchdog of the PMIC and service it.
As far as I have seen, the Q&A watchdog must be serviced by sending answers in two different timing-windows…
Hi Samir,
I assume this is LP877451A1RXVRQ1. But based on question this doesn't matter.
1. That is expected. If previous 4x answers were correct and after answer0 new Win1-Win2 needs to elapse before WD_FAIL_CNT[2:0] increments by one and reset occurs…
