DESCRIPTION

· The TPT29546 is a 1:4 bidirectional translating I2C switch.

· It allows the SCL/SDA upstream pair to fan out to four downstream channels.

· Channels can be selected via a programmable control register.

· Features an active-low reset input for recovery from a stuck low state.

· Supports voltage-level translation among 2.5V, 3.3V, and 5V buses.

· All I/O terminals are 5.5V tolerant.

· Available in TSSOP 16 and SOP16 packages, operating from -40°C to +85°C.

FEATURES

· Bidirectional translator for 1:4 I2C switch functionality.

· Active-low reset input for system recovery.

· Two address terminals, enabling up to four devices on the I2C bus.

· Operates with a power supply voltage range of 2.3V to 5.5V.

· Supports standard and fast mode I2C devices with clock frequencies up to 400 kHz.

· Low RON switches for efficient operation.

· Exceeds JESD 78 latch-up performance at 200 mA.

· Provides ESD protection exceeding JESD 22 standards.

APPLICATIONS

· Servers and storage systems.

· Routers and telecom switching equipment.

· Factory automation systems.

· Products with I2C slave address conflicts, such as multiple identical temperature sensors.
