TPS65981: I2C_IRQZ signal

Part Number: TPS65981

Hello,

What is the purpose of I2C_IRQZ pin of TPS65981?
I think it is not I2C standard signal and nobody seems to use this pin in its EVM.

Regards,
Satoshi Obata

    Hi Oba,

    The I2C_IRQZ signal is the I2C interrupt line. You can set multiple interrupt events on the TPS65981. When an interrupt is triggered, the I2C_IRQZ signal will be toggled to notify the host EC that there is an interrupt. The EC can then make changes and clear the interrupt.
