Part Number: TPS659039-Q1 Hi Team,
There is a good news that we DIN TPS659039-Q1
But need your support to DWIN!
Now have a cold rest issue :
Customer had been confirmed this PMIC failure mode in environment chamber. 1. Placed this board with failed PMIC in…
Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2SG what's reason can cause SMPS_1_2_3's voltage higher than 1.2V?
the TPS659039'S part mark code is:TPS659039 OTP 87 1.3
The SMPS_1_2_3 is dsigned 1.1V,but some board may be 1.25V…
Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2SX , Hi Expert,
My customer board using TDA2sx and TPS659039-Q1 but SW OUT/LDO OUT no output
PWRON and RPWRON are 16.348MHz。
OSC16MIN and OSC16MOUT 3.3V
Could you give us some advices?

Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2 Hi Team,
My customer now use O9039A387IZWS(T/R)Q1 to power TDA2x as EVM requested.
Customer order two different batches as following:
Batch1:
TPS659039
OTP 87 1.3
85C1G6W
LDO1_OUT=3.3V
B…
Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2SX , Hello:
I'm using TDA2sx and TPS659039-Q1，I found that TPS659039's LDO3 has unusually output as capcatured below.
I searched E2E and found that someone had resolved this issue by…
Part Number: TPS659039-Q1 Hi
After power on, the smps45 voltage changes from 1.06v to 1.175v (the load does not change). The measured voltage waveform is shown in the figure below. What is the reason? The datasheet is 1.06v.
Thanks！
Part Number: TPS659039-Q1 After power-up, customer found that the SMPS45 voltage change from 1.06V to 1.175Ｖ．
The test waveform could be found as following:
The output voltage is already written in OTP. Why it is change from 1.06V to 1.175V?
Part Number: TPS659039-Q1 Hi Team,

Part Number: TPS659039-Q1 Other Parts Discussed in Thread: TDA2 Hi，
I want to realize the following functions, can this PMIC chip be realized?
The GPADC_IN pin of the TPS659039 monitors several external voltages. When the set threshold is exceeded, the…
Part Number: TPS659039-Q1 Hi：
In our project，we found RESET_OUT pin has twice reset，as shown in the following figure. Please help to confirm whether this waveform is correct？and why the pin “RESET_OUT” has twice reset？
Thank you！
