MAX7313AEG+TG05

Overview

The MAX7313AEG+TG05 is a 16-port I/O expander with an additional general-purpose output, controlled via an 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 loads up to 5.5V. The device integrates 8-bit PWM control for LED intensity adjustment and two-phase blinking functionality. It features transition detection with interrupt output and supports hot insertion. The component is housed in a 24-pin QSOP package and operates within a temperature range of -40°C to +125°C.

Feature Summary

Integrated 8-bit PWM control for LED intensity and independent two-phase blinking
Transition detection with interrupt output for efficient input monitoring
Hot-insertion support with high-impedance inputs during power-down
Open-drain outputs rated at 50mA per port with 5.5V tolerance

Applications

LCD backlights
LED status indication
Portable equipment
Keypad backlights
RGB LED drivers

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and lead-free compliance. Ensure the supplier source matches the official Analog Devices or Maxim Integrated distribution channels. Confirm that the part number corresponds to the exact electrical specifications required for the target application environment.

Selection Notes

Select this component when a microprocessor requires expanded GPIO capabilities with integrated LED driving functions. It is suitable for applications needing hardware-level transition detection to reduce CPU load. Consider the 24-pin QSOP package constraints and the 2V to 3.6V supply requirement during system design.

Part Context

The MAX7313 is part of the Maxim Integrated I/O expander family, designed for serial peripheral expansion. It offers pin and software compatibility with similar devices like the MAX7311 and PCA9535 series. The device addresses the need for low-power, multi-channel I/O management in space-constrained portable electronics.

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 to ensure functional equivalence in the existing circuit design.
