MAX6946, MAX6947 10-Port, Constant-Current LED Driver And I/O Expander With PWM Intensity Control

The MAX6946 MAX6947 IC-/SMBus"-compatible, serial-interfaced peripherals provide Microprocessors with 10 I/O ports rated to 7V.
Each port CAN be configured as a 2.5mA to 20mA constant-current LED Driver (static or PWM), a 1.25mA to 10mA constant-current LED Driver (static or PWM), an open-drain Logic output, or an overvoltage-protected Schmitt Logic input.
Analog and switching LED intensity control includes individual 8-bit PWM control per output, individual 1-bit Analog current control (half/full scale) per output, and a global 3-bit DAC current control that applies to all LED outputs.
The MAX6946 MAX6947 CAN stagger the PWM Timing of the 10-port outputs in consecutively phased 45 increments. Staggering the outputs spreads the PWM load currents over time in eight steps, helping to even out the power-supply current and reduce the RMS current.
For a similar part with an SPI"-/QSPI"-/ or MICROWIRE"-compatible Interface refer to the MAX6966 MAX6967 data sheet.
