MAXIM INTEGRATED / ANALOG DEVICES MAX7315ATE I/O Expander
The MAX7315ATE+ is an 8-port I/O expander with LED intensity control, interrupt capability, and hot insertion protection, packaged in a 16-pin TQFN. This device offers an I2C/SMBus compatible serial interface, providing microprocessors with eight configurable I/O ports that can function as open-drain outputs with up to 50mA at 5.5V or as logic inputs with transition detection. An additional ninth port can serve as a transition detection interrupt or a general-purpose output. Outputs can directly drive LEDs or serve as logic signals with external pull-up resistors up to 5.5V. Integrated PWM control allows for fine-tuned LED brightness adjustment with global and individual 16-step intensity control. The device is suitable for LED status indicators, RGB LED drivers, LCD backlights, and keypad illumination. It supports a supply voltage range of 2V to 3.6V, operates in temperatures from -40°C to 125°C, and features a 400Kbps serial interface with 2-wire I2C/SMBus compatibility. It offers up to 64 I2C addresses, transition detection with interrupt output, and automatic LED blinking. The maximum output current per port is 50mA, with low standby current of approximately 1.2µA. Inputs are protected against overvoltage up to 5.5V. The device is pin and software compatible with PCA9534 and PCA9554(A).
