MAX6947ATE規(guī)格書(shū)詳情
General Description
The MAX6946/MAX6947 I2C-/SMBusTM-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.
Features
? 2.25V to 3.6V Operation
? I/O Ports Default to High Impedance (LEDs Off) on Power-Up
? I/O Port Inputs Are Overvoltage Protected to 7V
? I/O Port Outputs Are 7V-Rated Open-Drain, 10mA or 20mA Constant-Current Static/PWM LED Drivers, or Open-Drain Logic Outputs
? I/O Ports Support Hot Insertion
? Individual 8-Bit PWM Intensity Control for Each LED
? RST Input Clears Serial Interface and Can Exit Shutdown (Warm Start)
? MAX6946 OSC Input Allows for External PWM Clock Input
? MAX6947 AD0 Input Selects from Two Slave Addresses
? Auto Ramp-Up Out of Shutdown, and Up to 4s Hold-Off Before Ramp-Down into Shutdown
? 0.8μA (typ) Shutdown Current
? -40°C to +125°C Temperature Range
? Tiny WLP Package (4 x 4 Grid)
Applications
?? Cellular Phones
?? Portable Equipment
?? RGB LED Drivers
?? LCD Backlights
?? Keypad Backlights
?? LED Status Indicators
