Product Overview
The MAX7315AUE+ is an 8 port I/O expander with LED intensity control, interrupt and hot insertion protection in 16 pin TSSOP package. This I2C/SMBus compatible serial interfaced peripheral device provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current sinking output rated at 50mA at 5.5V or logic input with transition detection. A ninth port can be used for transition detection interrupt or as general purpose output. The outputs are capable of directly driving LEDs or providing logic outputs with external resistive pull-up up to 5.5V. PWM current drive is integrated with 8bits of control. Four bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully OFF to fully ON in 14 intensity steps. Each output then has individual 4bit control which further divides globally set current into 16 more steps. It is used in LED status indication, RGB LED drivers, LCD & keypad backlights.
- Supply voltage range from 2V to 3.6V
- Operating temperature range from -40°C to 125°C
- 400Kbps 2-wire serial interface, 5.5V tolerant
- Pin and software compatible with PCA9534 and PCA9554(A) devices
- Controlled through 2-wire I2C/SMBus serial interface & can be configured to one of 64 I2C addresses
- Transition detection with interrupt output, automatic two phase LED blinking
- Overall 8bit PWM LED intensity control, global & individual 16 step intensity control
- Maximum port output current is 50mA and serial clock frequency of 400KHz
- Low standby current of 1.2μA (typical) and 3.3μA (maximum)
- Inputs are overvoltage protected to 5.5V
