Part Number: TPS65072 Tool/software: I have a design that uses the TPS65072 power management IC. When I power the board on with 5V (on Vin in schematic), the 3.3V rail (VDCDC1 output) does not stabilize. The VSYS voltage drops and the TPS65072 turns off…
Udaya,
The software uses very specific API drivers for the GPIO interface that TI uses. The Aardvark is not compatible with these drives, so the software will not communicate with the Aardvark.
A lower current power adaptor can be used, but will limit…
Other Parts Discussed in Thread: DM3730 , TPS65072 We are seeing some weird behaviour. Our configuration is:
DM3730 GPIOs is controller the PB_IN and PWRON.
DM3730 I2C is used to control the PMIC.
When we have a battery below 3.0V, DM3730 won…
Other Parts Discussed in Thread: TPS65072 Hi all,
I am currently attempting to use the AD_IN1-4 pins as a AD converter to detect if a voltage from a seperate device is present. It seems that when I use the AD converter, by setting the TSCMODE register…
Hi Hongtao,
Figure 52 does show VLDO2 relation to VDCDC1 and VDCDC2. (See the picture below.) You are using the same revision as I am.
Since, you don't require the sequencing of the TPS65072 then I would recommend to you that you consider one of the…
Other Parts Discussed in Thread: TPS65072 , DM3730 I2C is open drain signal. Some of the input signals on TPS65072 could handle 1.8V signals (Power OK is VIH is 1.2V). But PB_IN required higher than 1.8V which is not 1.8V compatible.
For I2C, can…
Other Parts Discussed in Thread: TPS65072 , TPS65070 I have recently used a TPS65072 for making 3.3V, 2.5V and 1.2V FPGA voltages. Configuration is:
EN_DCDC1=EN_DCDC2=EN_DCDC3=1
POWER_ON=1
PB_IN=(I test 0 and leave open and the result was same)…
Other Parts Discussed in Thread: TPS65072 We are running into battery detection problem.
When the device is left on the shelf for long time, and battery is completely drain out, the low voltage protection circuit will cut out the cell.
When AC is…
Other Parts Discussed in Thread: TPS65072 I am using TPS65072. One of my test boards failed. It was working fine for a few months and then failed.
The part of the TPS65072 is working, I can turn it on and off through PB_IN and POWERON (DCDC1/2/3, LDO…
Other Parts Discussed in Thread: TPS65072 6835.TPS65072.pdf I have 3 boards failed to power up.
I disconnected the output.
Vbat = 3.9V
Vsys is 3.8V
AVDD6=3.8V
Power_ON is 3.8V
I toggled PB_IN, PGOOD is toggled with PB_IN ( PB_IN = 0, PGOOD…
