产品概述

The MAX6967AEE+ is a 10 port constant current LED driver and I/O expander with PWM intensity control in 16 pin QSOP package. This serial interfaced peripheral provides microprocessors with 10 I/O ports rated to 7V. PWM timing of 10 port outputs may be optionally staggered and consecutively phased in 45° increments. This spreads PWM load currents over time in eight steps, helping to even out the power supply current and reduce RMS current. The MAX6967 can be configured to awake from shutdown on receipt of minimum 3ms pulse on active-low CS input. This hardware wake-up feature allows power management controller or similar ASIC to enable MAX6967 with preconfigured LED intensity settings. Shutdown can be programmed to wait up to 4s, fade down the sink currents 7to zero for period of 1/16s to 4s and then shut down. The DOUT/OSC pin can be configured as either serial interface data output or optional PWM clock input. The MAX6967 defaults as OSC input.
  • Operating supply voltage range from 2.25V to 3.6V
  • Operating temperature range from -40°C to 125°C
  • High speed 26MHz SPI/QSPI/MICROWIRE compatible serial interface
  • I/O port outputs are 7V rated open-drain and I/O ports support hot insertion
  • I/O port outputs are 10mA or 20mA constant current static/PWM LED drivers/open-drain logic outputs
  • Internal PWM clock frequency range from 27000Hz to 45000Hz & external PWM clock frequency of 100KHz
  • Individual 8bit PWM intensity control for each LED, any output may use or not use PWM control
  • Auto ramp down into shutdown, auto ramp-up out from shutdown, 0.8µA shutdown current
  • I/O ports default to high-Z (LEDs Off) on power-up, I/O port inputs are overvoltage protected to 7V
  • Exit shutdown (warm start) with simple CS pulse
