The PCA9541APW/03,118 by NXP Semiconductors is a specialized interface integrated circuit designed for high reliability dual master I2C-bus applications. This device functions as a 2-to-1 I2C-bus master selector, allowing system operation to continue even if one master fails or is removed for maintenance.
Key electrical specifications include an operating voltage range of 2.3V to 5.5V and an interface supporting both I2C and SMBus protocols. The component is housed in a 16-TSSOP package, suitable for surface mount applications.
This IC is designed to isolate failed masters from the system without affecting communication between the online master and downstream slave devices. It offers interrupt outputs to indicate which master has control and supports bus recovery/initialization sequences. The pass gates allow for communication between different voltage bus levels, such as 1.8V, 2.5V, or 3.3V devices with 5V devices, provided external pull-up resistors are used on all channels.
