UAA145
Phase Control Circuit for Industrial Applications
Description
The UAA145 is a bipolar integrated circuit, designed to
provide phase control for industrial applications. It
permits the number of components in thyristor drive
circuits to be drastically reduced. The versatility of the
device is further enhanced by the provision of a large
number of pins giving access to internal circuit points.
Features
D Separate pulse output synchronized by mains
half wave
D Output pulse-width is freely adjustable
D Phase angle variable from >0° to <180°
D High-impedance phase shift input
D Less than 3° pulse symmetry between two half-cycles
or phase of different integrated circuits
D Output pulse blocking
Applications
D Industrial power control
D Silicon controlled rectifier
Package: DIP16 (special case)
