Part Number: TPS659039-Q1 Hi team,
My customer use TPS659039-Q1 power for TDA2S, but they meet one issue as follows:
1. Issue background
The board can be started normally when it is powered on for the first time, and then it can be powered off quickly…
Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2SX , Our customer consider to change ADAS SoC from TDA2SX to TDA2HFBTQABCQ1.
They were using O9039A387 as PMIC for TDA2SX.
Please let us know your recommend PMIC P/N for TDA2HFBTQABCQ1.

Part Number: TPS659039-Q1 Hi
The specification of TPS659039 mentions:
SMPS4 and SMPS5 cannot be used as separate converters. In dual-phase configuration the two interleaved synchronous buck regulator phases with built-in current sharing operate in opposite…
Part Number: TPS659039-Q1 Hi，
Regarding the application of PMIC, there are two questions:
Q1： One SMPS output of the PMIC is shorted for a few seconds, and it is measured that the SMPS has no output. At this time, we cannot reset the PMIC through POWERHOLD…
Part Number: TPS659039-Q1 Hi all,
I would like to ask 2 questions that confused me about TPS659039:
1. what are the functions of the external 16MHz crystal oscillator? In datasheet I saw it was used for a quick start right? Are there any other usage o…
Part Number: TPS659039-Q1 Hi,
Our schematic design of the TPS659039 does not use the LDO9 channel. Currently we design the LDO9 channel with an input voltage of 3.3V, but the output is open, and no decoupling capacitors are placed on the input and output…

PMU is changed from tps659039-q1 (o9039a387izwsrq1) to o9039a385izwsrq1. The abnormal log will appear in Linux system and…
Part Number: TPS659039-Q1 Hi Team,
Since TPS659039-Q1's M11 pin is 32-kHz digital-gated output clock available when VIO_IN input supply is present. I have one questions:
1. Does M11 has stable frequency output with 250 ppm accuracy?
If it works, customer…
Part Number: TPS659039-Q1 Hi team,
I wondering is that possible to pull up POWERDOWN to 3.3V?
and what is the meaning of without fail-safe and with fail-safe?
Thanks
