G1625 - 7-bit Programmable VCOM Reference

Description

The G1625 provides a programmable reference voltage for TFT-LCD panel VCOM adjustment.

A 7-bit digital-to-analog converter (DAC) detects current from an external resistor-divider to create the VCOM reference voltage.

This voltage is used as the input to a high current drive voltage buffer.

Features

  • Integrated Nonvolatile Memory to Store VCOM Setting.
  • 100 Programming Times.
  • I 2C Interface.
  • 7-Bit, Adjustable Sink-Current Device.
  • Resistor-Adjustable, Full-Scale Range.
  • 2.5V to 3.6V Logic Supply Range.
  • 7V to 18V Analog Supply Range.
  • Protections:.
  • Over Current Protection (OCP).
  • Over Temperature Protection (OTP).
  • TDFN3X3-8 Package.
  • RoHS Compliant.
