ISL3179EFBZ-T

ISL3179EFBZ-T Application Field and Working Principle

The ISL3179EFBZ-T is an integrated circuit (IC) designed for open-collector or open-drain applications. It is an I2C-bus transceiver consisting of a driver and a receiver for open-collector control and signal conversion. The circuit provides one half-bridge driver and one driver/receiver pair, both of which operate from a single supply voltage.

Application Field

The ISL3179EFBZ-T is suitable for open-collector signal conversion and signal power control in automotive, industrial and consumer applications. It can be used for signal translation in 3V to 28V logic and I/O signal power control in a variety of environments. It has been designed for use in I2C-bus controlled, open-collector control systems, or any system requiring signal conversion and signal power control between 3V to 28V.

Working Principle

The ISL3179EFBZ-T is composed of a driver and a receiver. The driver is responsible for the control and signal conversion between 3V and 28V logic levels. Regenerative logic is used in the driver block. Output signals are connected to pullup resistors on the I2C-bus line. When the output exceeds the input level, the output is pulled up to the desired level. This feature creates a push-pull effect between two I2C bus lines, enabling reliable data communication.

The receiver block on the ISL3179EFBZ-T is capable of accepting and converting signals from 3V to 28V logic levels. It is used for data transmission and reception of information from the I2C-bus. The receiver is enabled when the output is high and disabled when the output is low. This ensures that the receiver does not lose data if the communication bus goes down.

The ISL3179EFBZ-T is a single device driver/receiver I/O circuit offering low voltage open collector operations and fast response time. This circuit combines both the driver and receiver in one IC, providing a cost-effective solution for signal conversion and signal power control.
