TCA9539RGER

Overview

The TCA9539RGER is a low-voltage 16-bit I2C and SMBus low-power I/O expander manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V, supporting standard, fast, and high-speed modes up to 400 kHz. The device features an interrupt output, a reset pin, and configuration registers for flexible control. It is housed in a VQFN-24 package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

Supports I2C and SMBus communication protocols with interrupt output capability
Includes dedicated reset pin and configuration registers for input/output control
Operates at low power consumption suitable for battery-powered applications

Applications

Portable consumer electronics requiring extended I/O capabilities
Industrial control systems utilizing I2C/SMBus interfaces
Automotive infotainment and body electronics modules

Procurement Notes

Verify the specific suffix RGER corresponds to the VQFN-24 tape-and-reel packaging format when sourcing. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the supplier provides valid traceability documentation for quality assurance purposes prior to final acquisition.

Selection Notes

Select this component when a 16-bit expansion is required on an I2C or SMBus bus with low voltage operation. The integrated reset pin and interrupt output simplify system design compared to basic expanders. Verify that the VQFN-24 package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the TCA9539 family of low-voltage I/O expanders from Texas Instruments. It shares functional similarities with other members like the TCA9535 but offers specific interface and package variations. The RGER suffix denotes the commercial grade version in a reel-packaged VQFN-24 form factor.

Replacement Considerations

The TCA9539RTWR serves as a direct alternative in a WQFN-24 package. For automotive applications, consider the TCA9539BQPWRQ1 which offers extended temperature ratings and AEC-Q100 qualification.
