MAX7313DATG+

Overview

The MAX7313DATG+ is a 16-port I/O expander with integrated LED intensity control, interrupt capability, and hot-insertion protection. It features an I2C-compatible serial interface operating at up to 400 kHz. The device supports a supply voltage range of 2V to 3.6V and operates within a temperature range of -40°C to +125°C. Each I/O port can be configured as an open-drain current-sinking output rated at 50mA and 5.5V, or as a logic input with transition detection. A 17th port serves as an interrupt output or general-purpose output. The component utilizes a 24-pin TQFN package.

Feature Summary

Integrated PWM current drive with 8-bit control for LED intensity adjustment
Supports hot insertion with high-impedance state during power-down
Transition detection with interrupt output functionality
Two-phase LED blinking with independent timing per output

Applications

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

Procurement Notes

Verify the specific ordering suffix DATG+ corresponds to the lead-free/RoHS-compliant 24-pin TQFN-EP package variant. Confirm that the manufacturer designation matches Maxim Integrated or Analog Devices Inc. documentation. Ensure the part number aligns with the specified -40°C to +125°C temperature range and electrical characteristics provided in the official datasheet.

Selection Notes

Select this component when a microprocessor requires expanded I/O capabilities via an I2C interface. It is suitable for applications needing individual LED brightness control through PWM. Consider the 50mA sink current capability and 5.5V tolerance for driving external loads. Verify compatibility with existing I2C bus addressing schemes using the AD0-AD2 pins.

Part Context

The MAX7313 is pin and software compatible with the MAX7311, PCA9535, and PCA9555. This compatibility allows for potential design flexibility or migration between these devices without significant schematic or firmware changes. The device belongs to the Maxim Integrated peripheral family designed for general-purpose input/output expansion.
