Hi,
My client company is developing EPD (Electric Paper Display) using TPS651851.
During EPD development, I have a request for a review of the circuit diagram.
(Review of attached circuit diagram)
EPD_PM-IC_SCHEMATIC2020104.pdf
In addition, the EPD power block diagram is attached.
There are Request Contents on pages 5 and 6 of the block diagram.
Please answer your questions.
EPD DISPLY PM IC CONTROL schematic.pptx
[page 5]
EPD PM-IC POWER: It will receive power from system PM-IC(ALL Voltage control)
Is there no problem? (VSYS=5V)
[page 6]
2. EPD DISPLAY Temperature control
Can I use the NTC circuit for EPD DISPLAY THERMAL CONTROL?
Is it programmed to enable NTC control in TPS651851PM-IC?
Is it possible to I2C control with EPD DRIVER IC?
Thank you.
Regards.
