AMG-LI080

Timer/Dimmer with Gate Driver, Zero Detection & Protection

1. Functional Description

The AMG-LI080 is a timer IC with a gate driver output for MOSFETs. The timer is set by a

zero crossing detector and reset by external RC. This IC features protection against over-

current, over-voltage and over-temperature. This IC is well suited for several kinds of dimmer

and timer applications.
