MAX7315ATE+

Overview

The MAX7315ATE+ is an I2C/SMBus-compatible 8-port I/O expander with integrated LED intensity control and hot-insertion protection. It operates on a supply voltage of 2V to 3.6V, while its open-drain outputs tolerate external voltages up to 5.5V. The device supports a maximum serial clock frequency of 400kHz and provides a maximum port output current of 50mA. It features low standby current, typically 1.2µA, and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrated PWM LED intensity control with global and individual settings
Supports hot insertion with high-impedance pins during power-down
Transition detection with interrupt output capability
Pin and software compatible with PCA9534 and PCA9554(A)

Applications

LCD backlights
LED status indication
Portable equipment
Laptop computers
Keypad backlights

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout and electrical specifications. Ensure the ordering suffix matches the required package type and temperature range. Cross-reference datasheet parameters for interface compatibility and voltage tolerances before integration into the design.

Selection Notes

Select this component when an I2C interface is required for expanding GPIO capabilities alongside LED driving functions. Consider the 5.5V tolerant outputs if interfacing with higher voltage logic levels than the core supply. Evaluate the low standby current requirements for battery-operated applications where power efficiency is critical.

Part Context

The MAX7315 belongs to the Maxim Integrated I/O expander family, designed for microprocessor peripheral expansion. It combines standard GPIO functionality with specialized LED control features, offering a compact solution for systems requiring multiple outputs in a small footprint. The device integrates internal oscillators for PWM generation without external components.

Replacement Considerations

The MAX7315 is pin and software compatible with the PCA9534 and PCA9554(A). Verify that substitute devices support the same 5.5V output tolerance and hot-insertion characteristics. Confirm that the alternative part number maintains identical register mapping and I2C addressing schemes.
