Product Summary
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 UAA145 is further enhanced by the provision of a large number of pins giving access to internal circuit points. Applications include Industrial power control and Silicon controlled rectifier.
Parametrics
UAA145 absolute maximum ratings: (1)Positive supply voltage: 18V; (2)Shift voltage: 5V; (3)Reverse voltage, control input: 15V; (4)Synchronization current: 20mA; (5)Control input pulse current: 3mA; (6)Total power dissipation: 500mW; (7)Junction temperature: 125℃; (8)Ambient temperature range: -25~70℃; (9)Storage temperature range: -25~125℃.
Features
UAA145 features: (1)Separate pulse output synchronized by mains half wave; (2)Output pulse-width is freely adjustable; (3)Phase angle variable from >0℃ to <180℃; (4)High-impedance phase shift input; (5)Less than 3°pulse symmetry between two half-cycles or phase of different integrated circuits; (6)Output pulse blocking.
