Product Introduction

Overview

The PCA9509GM,125 from NXP USA Inc. is a level translating I2C-bus/SMBus repeater designed to facilitate communication between low-voltage and standard-voltage I2C-bus or SMBus systems. This component enables seamless integration of processors operating at lower voltages with standard I2C-bus or SMBus interfaces, ensuring no degradation in system performance. The PCA9509GM,125 is particularly useful in mixed-voltage systems where compatibility between different voltage levels is crucial.

Key Features

  • Level Translation: Enables communication between low-voltage and standard-voltage I2C-bus or SMBus systems without performance degradation.
  • Bidirectional Open-Drain Buffers: Supports up-translation and down-translation between the two buses.
  • Over-Voltage Tolerance: Port B I/Os are tolerant to 5.5 V even when the device is unpowered.
  • Power-Up Circuitry: Keeps output drivers turned off until VCC(B) is above 2.5 V.
  • Low Power Consumption: Optimized for low power supply currents on both ports.

Applications

  • Mixed-Voltage Systems: Ideal for systems where processors operate at different voltage levels.
  • Industrial Automation: Used in industrial control systems that require communication between devices at different voltage levels.
  • Consumer Electronics: Suitable for various consumer electronic devices that need to interface with different voltage-level components.
  • Automotive Systems: Used in automotive systems for reliable communication between different modules operating at various voltage levels.
