MAX7313ATG+T

Overview

The MAX7313ATG+T is a 16-port I/O expander with an integrated I2C/SMBus interface. It operates on a supply voltage of 2V to 3.6V and supports a clock frequency up to 400 kHz. Each port provides open-drain current-sinking output rated at 50mA, capable of driving external loads up to 5.5V. The device features 8-bit PWM LED intensity control with global and individual settings, two-phase LED blinking, and transition detection interrupt capabilities. It is housed in a 24-TQFN (4mm x 4mm) package with an exposed pad.

Feature Summary

Integrated 8-bit PWM control for LED intensity adjustment
Transition detection with interrupt output generation
Supports hot insertion with high-impedance protection
Configurable as inputs or outputs with independent blink timing

Applications

LCD Backlights
LED Status Indication
Portable Equipment
Keypad Backlights
RGB LED Drivers

Procurement Notes

Verify the component against official Analog Devices/Maxim Integrated datasheets to confirm authenticity. Ensure the ordering suffix matches the required temperature range and packaging specifications. Cross-reference pin configurations and electrical characteristics with the manufacturer's documentation before integration into designs.

Selection Notes

Select this component when a microprocessor requires expanded I/O ports via a serial interface. It is suitable for applications needing LED intensity control and transition detection. Verify compatibility with existing I2C bus addresses and ensure the operating voltage range aligns with system requirements.

Part Context

The MAX7313 is part of the Maxim Integrated I/O expander family. It offers pin and software compatibility with devices like the MAX7311, PCA9535, and PCA9555. This allows for potential design flexibility and migration within compatible peripheral solutions.

Replacement Considerations

The MAX7313 is pin and software compatible with the MAX7311, PCA9535, and PCA9555. These parts can serve as direct replacements if they meet the specific electrical and functional requirements of the application.
