Part Number: TPS65186 Other Parts Discussed in Thread: TPS65185 We have a board with TPS65186 on it.
Before TPS65186 power on , the VCOM pin have -100mV of Vlotage form other pcb circuit.
And than the TPS65186 is damaged。
Can you tell me -100mV of Vlotage on …
Part Number: TPS65186 Other Parts Discussed in Thread: TPS65185 Hello, I have made a board that uses TPS65186. I can read & write the register via i2c protocol, and I can activate it by ENABLE register(I tried PWRUP pin also).
but all power rail not…
Part Number: TPS65186 I use TPS65186 for my eink panel for power supply
When I power on the chip and pull up the wake up pin, I read out all register and find out some value is different with datasheet, list below:
addr read default
0x02 0x03 0x2…
Part Number: TPS65186 Other Parts Discussed in Thread: TPS65185 Hello, recently I have made the circuit for TPS65186, I followed most of the design guide given in documentation of EVM of TPS65185. So far all my circuit is good, except for it does not…
Part Number: TPS65186 Hi
Are there any rules for the power up/down sequence between Vbattery(VIN, VIN_P, VB_SW) and VIN3P3?
VIN3P3 is also used for I2C pullup, PG pullup and INT pullup.
Customer inputed VIN3P3 firster than Vbattery. At this time, they…
Part Number: TPS65186 Other Parts Discussed in Thread: TPS65185 HI,
I am designing an e-paper display using TPS65185. But due to I2C address clash with another IC in the mother board I am moving to TPS65186. On comparison between the two ICs I found a…
Part Number: TPS65186 I have created a PCB with the reference design from the data sheet. Although the chip wakes up and can communicate through the I2C, I cannot get it to power up the supplies. When PWRUP is pulled high, the oscillator begins running…
Part Number: TPS65186 Other Parts Discussed in Thread: TPS65185 Hi Team,
Customer would like do E paper application.
Originally we propose TPS65186 to replace the MAX17135.
However, TPS65186 PMIC spec, it can boost max 16v for VPOS function. TPS65186 cannot…
Hi Frank,
This artifact may be specific to this particular PDF viewer, can this be verified by viewing the PDF in a separate program?
For specific component values please verify within the parametric tables or recommended operating conditions tables…
Other Parts Discussed in Thread: TPS65186 Hello,
I am trying to power up the TPS65186 epaper power chip but any time I try to power up the rails I get a VCOM fault (INT2 register has bit 2, the 3rd bit, set). I measure voltage on VCOM and it is around…
