概述

Description

The PCA9546APWR is a 4-channel I2C multiplexer designed to expand the number of I2C devices that can be connected to a microcontroller or processor. It allows multiple I2C buses to be controlled independently, enabling the connection of several I2C devices with the same address on separate channels. This is particularly useful in applications where limited I2C addresses are available.
Key features include:
- Multiple Channels: It has four independent channels, allowing for the selection of one active channel at a time.
- Addressing: The device supports standard I2C addressing with a 7-bit address.
- Low Power Consumption: It operates with low power, making it suitable for battery-operated devices.
- Wide Operating Voltage: It works with a supply voltage range typically from 2.3V to 5.5V.
- Compatibility: Compatible with standard I2C protocols, making it easy to integrate into existing systems.
Overall, the PCA9546APWR is essential for managing multiple I2C devices efficiently.

Features

The PCA9546APWR is an I²C multiplexer that allows multiple I²C buses to be connected to a single I²C master device. Key features include:
1. Channel Configuration: It has 6 channels (A0-A5) that can connect up to 6 different I²C bus segments.
2. Addressing: The device can be configured with different addresses using two address pin options, enabling multiple PCA9546A devices on the same bus.
3. Single Master Control: Only one channel can be active at a time, preventing bus contention.
4. Power-On Reset: It features a power-on reset function that ensures the device starts in a known state.
5. Wide Voltage Range: Operates from 2.3V to 5.5V, making it flexible for various applications.
6. Low Power Consumption: Suitable for battery-powered applications.
7. I²C Compatibility: Fully compliant with I²C specifications, allowing easy integration into I²C systems.
These features make the PCA9546APWR ideal for managing multiple I²C devices, enhancing system design flexibility and efficiency.

Package

The PCA9546APWR is packaged in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration.

Pinout

The PCA9546APWR is an I2C bus multiplexer with a pin count of 16. It allows multiple I2C buses to connect to a single master bus while ensuring that only one slave device is active at a time.
Pin Functions:
1. GND (Pins 1, 8): Ground reference.
2. VDD (Pin 2): Supply voltage (typically between 2.3V and 5.5V).
3. SDA (Pin 3): Serial Data Line (I2C data line).
4. SCL (Pin 4): Serial Clock Line (I2C clock line).
5. A0, A1, A2 (Pins 5, 6, 7): Address selection pins to configure the I2C address.
6. H0, H1, H2, H3 (Pins 9, 10, 11, 12): High-speed I2C channel outputs.
7. L0, L1, L2, L3 (Pins 13, 14, 15, 16): Low-speed I2C channel inputs.
