HT2040A - Christmas Light Controller

Datasheet Summary

Description

The HT2040A is a low cost, low power CMOS LSI chip designed for use in Christmas lighting control products.

It provides 4 SCR outputs to control the lamps.

The lamps can display up to 10 different groups of lighting patterns, where each pattern or pattern group is chosen by appropriate input keys.

Features

  • Operating voltage: 4.5V~5.5V 4 SCR direct drive outputs 10 different groups of lighting patterns Up to 8 patterns for each group Demonstration function One key activation function.
  • Up to 23 patterns can be programmed inside Built-in PLL circuit 50Hz or 60Hz AC power supply.
