产品概述

The MAX7304ETG+ is an I2C interfaced, 16 port, level translating GPIO and LED driver with high level of integrated ESD protection in 24 pin TQFN package. It consists of 16 port GPIOs with 12 push-pull GPIOs and four open-drain GPIOs configurable as PWM controlled LED drivers. The device supports 1.62V to 3.6V separate power supply for level translation. Each GPIO can be programmed to one of the two externally applied logic voltage levels. PORT15-PORT12 can also be configured as LED drivers that feature constant current sinks and PWM intensity control with internal oscillator. The maximum constant current level for each open-drain LED port is 20mA. The intensity of LED on each open-drain port can be individually adjusted through 256 step PWM control. The port also features LED fading. The same index rows and columns in device can be used as a direct logic level translator.
  • Operating supply current of 50µA and sleep mode supply current of 1.8µA
  • Operating temperature range from -40°C to 85°C
  • 8-channel individual programmable level translators and four LED driver pins on PORT15 to PORT12
  • Integrated high ESD ( ±8KV IEC 61000-4-2 contact discharge, ±15KV IEC 61000-4-2 air gap discharge)
  • 5V tolerant, open-drain I/O ports capable of constant current LED drive
  • 256 step PWM individual LED intensity control accuracy and supports hot insertion
  • Individual LED blink rates and common LED fade-in/out rates from 256ms to 4096ms
  • 400Kbps, 5.5V tolerant I2C serial interface with selectable bus timeout
  • Configurable edge triggered port interrupt and user configurable debounce time (1ms to 32ms)
  • Individually programmable GPIOs to two logic levels
