LED1642GW - 16-channel LED driver

General Description

The LED1642GW is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays.

The LED1642GW guarantees 20 V output driving capability allowing the user to connect several LEDs in series.

Key Features

  • 16 constant current output channels.
  • Output current: from 3 mA to 40 mA.
  • Current programmable through external resistor.
  • 7-bit global current gain adjustment in two ranges.
  • 12/16-bit PWM grayscale brightness control.
  • Programmable output turn-on/off time.
  • Error detection mode (both open and shorted- LED).
  • Programmable shorted-LED detection thresholds.
  • Auto power saving/auto-wakeup.
  • Selectable SDO synchroniz.
