The TI E2E™ design support forums will undergo maintenance from July 11 to July 13. If you need design support during this time, open a new support request with our customer support center.
Part Number: TPS274C65 Other Parts Discussed in Thread: TPS2HCS10-Q1 Tool/software: Dear Support team,
Where can I find the documentation to implement the CRC in SPI communication?
The required information is missing in the datasheet provided by TI.

Part Number: TPS274C65 Tool/software: We're using the TPS274C65AS in a system with a host microcontroller, DSPI=0, CRC_EN=0. In some circumstances, the microcontroller might need to restart or will otherwise lose its in-RAM state, which will also…
Hi Tim,
the voltage drop occurs on the data line output (SDO) of the TPS274C65 device (MISO of the SPI interface). I'm not convinced that a 1M pull-down resitor could be the main reason for this behaviour, but thank you very much for your research…
Part Number: TPS274C65 Tool/software: Hi Team,
I would like to check the meaning of the following sentences
8.3.5.8 Power-Up and Power-Down Behavior:
in case the VDD power supply is enabled the first and the VDD voltage exceeds VDD,UVLOR before the…
Part Number: TPS274C65 Tool/software: Hi Ti experts,
My customer uses TPS274C65AS in PLC IO module. They met some issues and have five questions:
Q1: After power-on, 0h register is 0x81 or 0xC1, which means there is a UVLO case. Is it normal. Is there…
Part Number: TPS274C65 Tool/software: Hello,
I have a question on the datasheet for this device.
The specs for the maximum PWM frequency at 1kHz:
The waveform below shows a 5% duty cycle, 250 Hz signal, so the pulse width is 200µs.
Are we…
Part Number: TPS274C65 Tool/software: RILIM in Table 9-1, PG 77 of datasheet is the only mention on setting the current limit threshold via a resistor to ground. As per the datasheet: "Set current limit threshold, connect from pin to IC GND"…
Part Number: TPS274C65 Tool/software: Dear support team,
can you please provide some documentation or information about the CRC calculation of the TPS274C65?
There is no description of this calculation in the data sheet.
Thanks in advance.
Part Number: TPS274C65 Other Parts Discussed in Thread: TPS274160 , , TPS4H000-Q1 Tool/software: I need a way to monitor switched outputs in a (12V) alarm system. I got excited as the TPS274C65AS was exactly what I was looking for. And if not for the fact…
