Universal Timer Controller

Features

Description



Auto-shut off output once time-out

Universal timer is a mixed signal CMOS IC

designed for a fixed timer to drive external SCR to

implement safety power control. It is applied to

120V/240V and 50/60Hz AC power supply. It can

automatically shut-off load in order to prevent undesired

conditions from the system. Internal timer can present

several kinds of different time: 15mins, 30mins, 45mins,

1hr, 1.5hrs, 2hrs, 4hrs and 8hrs, which is decided by part

number.

Button to ON/OFF/RESET timer

Available timer with high precision same as AC

50/60Hz



Build-in RC oscillator

Drive external SCR

Support 50/60Hz by part

Quick Test Mode (QTM) for manufacturer

Available timer of 15/30/45/60/90/120/240/480min

Low cost lead free package: TO-92 or DIP-8 or

SOIC-8
