19-0598; Rev 0; 7/06 10-Port, Constant-Current LED Drivers and I/O Expanders with PWM Intensity Control General Description The MAX6946/MAX6947 I2C*-/SMBus TM-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 indicom vidual 8-bit PWM control per output, individual 1-bit analog current control (half/full scale) per output, and a global 3-bit DAC curren...
