Product Description

The PCA9515DP is an I2C Repeater and I2C Bus Buffer IC designed to extend the capacity of I2C bus systems. It supports bidirectional communication across two separate I2C bus segments, enabling seamless connectivity between multiple devices. Functioning as a 5V I2C Level Shifter, it bridges I2C networks operating at different voltage levels (2.3V to 5.5V), ensuring compatibility between low-voltage and high-voltage modules. The device features dual bidirectional channels, allowing direct interfacing of up to two I2C bus segments while isolating capacitance to prevent signal degradation. It is ideal for industrial automation, embedded systems, and communication equipment requiring extended bus reach or mixed-voltage operation. Key advantages include low standby current, automatic direction sensing, and robust noise immunity. However, it lacks built-in surge protection and may require external components for high-noise environments. The PCA9515DP operates within a temperature range of -40°C to +85°C, ensuring reliability in harsh conditions.
