MAX7313DATG+T

Overview

The MAX7313DATG+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 maximum clock frequency of 400 kHz. Each port provides open-drain current-sinking capability rated at 50mA, with external pullup support up to 5.5V. The device features 8-bit PWM LED intensity control, two-phase blinking, and transition detection with interrupt output. It is housed in a 24-TQFN (4mm x 4mm) package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrated 8-bit PWM control for LED intensity adjustment
Transition detection with interrupt output generation
Supports hot insertion with high-impedance power-down state
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 package type and temperature grade. Cross-reference part numbers with authorized distributors to validate supply chain integrity before procurement.

Selection Notes

Select this component when a microprocessor requires expanded GPIO via I2C with specific LED driving capabilities. Consider the 50mA sink current and 5.5V tolerant outputs for direct LED interfacing. Verify that the 24-pin TQFN package fits the PCB layout constraints and thermal requirements.

Part Context

The MAX7313 series serves as a general-purpose peripheral for microprocessors, providing 16 configurable I/O ports. It is pin and software compatible with devices like the MAX7311, PCA9535, and PCA9555. The DATG+T variant specifically denotes the industrial temperature range and tape-and-reel packaging format.

Replacement Considerations

The MAX7313 is pin and software compatible with the MAX7311, PCA9535, and PCA9555. Verify register mapping and electrical characteristics before substituting these parts.
