Hi team,
Our customer is using the TCA6416 for their project.
And we have some questions:
1. Could you help to confirm how long it takes for the chip from I2C driver configuration finish to…
Part Number: TCA6416A Dear Team,
What is the maximum resistance of the int pin pull up of tca6416a?
I want to use it in the battery project, but I found that if his int pin uses the suggested line of 10K, the leakage current will be too large. Can I…
Part Number: TCA6416A Hi,
I am controlling a DC amp motor via a TI motor driver DRV8874PWPR, and controlling the motor driver chip via the port expansion chip. The motor pulls about 1.0 amp at 24 volts. Everything is fine normally, but when the motor hits…

Part Number: TCA6416A Other Parts Discussed in Thread: TCA6416 , TCAL6416 Hi Team,
We would like to have the following startup sequence, Vcci, Vccp, Reset_high. It's noted in the DS that it is recommended Vccp should come up before Vcci, with the RESET…
Part Number: TCA6416A Hi team, I'd like to know about the powerup sequence. The following wording has been added in accordance with the changes in the datasheet. "Ramping up the device VCCP before VCCI is recommended to prevent SDA from potentially being…
Part Number: TCA6416A To whom it may concern,
We would like to operate the TCA6416A from a 3.3 V SMBus, but have it drive/receive 1.8 V IO. What is the power-on timing requirement? Does this device support partial power-on operation without leakage?
Thank…
Part Number: TCA6416A Other Parts Discussed in Thread: TCA6416 Hello guys,
One of my customers is using TCA6416APWR for their current mass production. But they want to use TCA6416PWR instead of TCA6416APWR due to long lead time.
They found that TCA6416…
