Part Number: TPS65950
I want to write data to the MEMORY-DATA register, but no matter what value I write to the MEMORY-DATA register, the value I read is a default value, which means I did not successfully write to the MEMORY-DATA register. I have found…
Part Number: TPS65950 I found a tolerance for the prescaler on the VBAT of 20% (table 5-70 in the TPS65950 datasheet, specifies 0.2~0.3V/V).
This tolerance is extremely wide, but I also can’t find a tolerance for any of the other ADCs (I specifically…
Hi Kevin,
This device is a legacy device with very limited design knowledge and support so please bear with me as we both work to understand the PMIC.
1. I am having a hard time finding I2C_CNTL, is this a register in TPS65950 or in the processor…

Hi Murthy,
Just wanted to clarify one doubt, as per TPS manual section section 9.4.7, If the current from the charger is less than 0.85 A in the battery charge mode, the slope used to adapt the
MADC range is 0.88 mV/mA. For higher current, the slope…
Part Number: TPS65950 Hi team,
valued customer has some general questions regarding the data converters. for starters please help with the below.
ADC:
1. could we get an explanation about the prescaler and how that works for the ADC? In other…
Part Number: TPS65950 In the TPS65950 OMAP document ("TPS65950 OMAP(TM) Power Management and System Companion Device ES 1.2 TRM (Rev. G)" at http://www.ti.com/product/TPS65950/technicaldocuments ), the ARXL1_APGA_CTL Register (table 14-38 on page 758…
Hello,
There are many reasons a particular design can have issues. Changing input supplies for LDOs can have several impacts. First would be that reducing the VIN voltage should reduce the power consumption of the system. Perhaps the battery was not…
Part Number: TPS65950 Other Parts Discussed in Thread: DM3730 I'm looking at the PCB layout guide for the TPS65950 (document swcu055a), and in Figure 3 I see a recommended scheme for pads with a trace between them, including a pad diameter of 220 um.…
