MAX7360ETL+

Sensor And Detector Interfaces Overview

The MAX7360ETL+ is an I2C-interfaced peripheral providing microprocessors with management of up to 64 key switches and eight LED drivers/GPIOs. It features constant-current, PWM intensity control, and rotary switch options. Key inputs are monitored statically for low-EMI operation. The device includes autosleep and autowake modes to minimize power consumption, entering a low-power state (1µA typ) after a programmable timeout. It operates over the -40°C to +85°C extended temperature range in a 40-pin TQFN package.

Sensor And Detector Interfaces Feature Summary

• Integrated ESD protection rated at ±8kV contact discharge and ±15kV air-gap discharge per IEC 61000-4-2
• +14V tolerant open-drain I/O ports capable of constant-current LED drive
• Rotary switch-capable input pair on PORT6 and PORT7 accepting 2-bit gray code
• 256-step PWM individual LED intensity control with configurable blink rates

Sensor And Detector Interfaces Applications

• Cell Phones
• PDAs
• Handheld Games
• Portable Consumer Electronics
• Printers

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix ETL+ corresponds to the 40-pin TQFN-EP package variant. Confirm RoHS compliance status as indicated by the plus sign. Ensure the supplier provides documentation matching the Analog Devices or Maxim Integrated datasheet specifications for this exact part number.

Sensor And Detector Interfaces Selection Notes

Select this component when static matrix monitoring is required to minimize electromagnetic interference in dense layouts. Consider the +1.62V to +3.6V operating voltage range and the availability of four I2C address choices for system integration. Evaluate the FIFO queue capacity for handling debounced key events efficiently.

Sensor And Detector Interfaces Part Context

The MAX7360 series includes variants such as the MAX7360EWX+ in a 36-bump WLP package. Both versions share identical electrical characteristics and functionality but differ in physical footprint and pin count. The ETL+ designation specifically identifies the thin QFN package suitable for applications requiring exposed pad thermal dissipation.

Sensor And Detector Interfaces Replacement Considerations

The MAX7360EWX+ serves as a direct functional substitute offering identical performance in a wafer level package format.
