MAX6947ATE+T Products
The MAX6946/MAX6947ATE+ I2C-/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/MAX6947ATE+ 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.
