MAX7315 Product details

General Description
The MAX7315 I2C-/SMBus-compatible serial interfaced peripheral 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 a logic input with transition detection. A ninth port can be used for transition detection interrupt or as a general purpose output. The outputs are capable of directly driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V.
PWM current drive is integrated with 8 bits 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 4-bit control, which further divides the globally set current into 16 more steps. Alternatively, the current control can be configured as a single 8-bit control that sets all outputs at once.

Features
♦ 400kbps, 2-Wire Serial Interface, 5.5V Tolerant
♦ 2V to 3.6V Operation
♦ Overall 8-Bit PWM LED Intensity Control
   Global 16-Step Intensity Control
   Plus Individual 16-Step Intensity Control
♦ Automatic Two-Phase LED Blinking
♦ 50mA Maximum Port Output Current
♦ Supports Hot Insertion
♦ Outputs Are 5.5V-Rated Open Drain
♦ Inputs Are Overvoltage Protected to 5.5V
♦ Transition Detection with Interrupt Output
♦ Low Standby Current (1.2µA typ; 3.3µA max)
♦ Tiny 3mm x 3mm, Thin QFN Package
♦ -40°C to +125°C Temperature Range
♦ All Ports Can Be Configured as Inputs or Outputs

Applications
   LCD Backlights
   LED Status Indication
   Portable Equipment
   Laptop Computers
   Keypad Backlights
   RGB LED Drivers
   Cellular Phones
