Power management system, method for transmitting data in a power management system, and integrated circuit

A method for transmitting data in a power management system, comprising:

• transmitting, via a system power management interface (SPMI) master circuit, a command to a SPMI slave circuit through an interface bus connected between the SPMI master circuit and the SPMI slave circuit, wherein the interface bus is a SPMI;
• and
• performing, via the SPMI master circuit, a retransmission process which comprises:
• retransmitting, via the SPMI master circuit, the command to the SPMI slave circuit through the interface bus, in response to not receiving an acknowledgement message from the SPMI slave circuit for longer than a pre-determined period of time after transmitting the command.

An integrated circuit, comprising:

• a system power management interface (SPMI) master circuit, configured to:
• transmit a command to a SPMI slave circuit through an interface bus connected between the SPMI master circuit and the SPMI slave circuit, wherein the interface bus is a SPMI;
• and
• perform a retransmission process which comprises:
• retransmitting the command to the SPMI slave circuit through the interface bus, in response to not receiving an acknowledgement message from the SPMI slave circuit for longer than a pre-determined period of time after transmitting the command.
