G1625

Global Mixed-mode Technology

7-bit Programmable VCOM Reference

with Integrated Nonvolatile Memory

Features

General Description

Integrated Nonvolatile Memory to Store VCOM

Setting

The G1625 provides a programmable reference volt-

age 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 refer-

ence voltage. This voltage is used as the input to a

high current drive voltage buffer.

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

G1625 includes one time programmable (OTP) mem-

ory to store the DAC code on the chip, eliminating the

need for external EEPROM. The chip supports up to

100 write operations to OTP memory. G1625 has an

I²C interface to set the VCOM reference voltage and

write into OTP memory.

RoHS Compliant
