TEMIC Semiconductors TEA1007

The phase-shift of the ignition point is determined in the usual manner by comparison between a mains synchronized ramp voltage and a predetermined required value. The capacitor Cö/t between Pin 7 and the common reference point Pin 8 is discharged at the zero transition of the mains voltage via the Vo detector, gate G2 and switch S2.

DESCRIPTION

Integrated circuit, TEA1007, is designed as a general phase control circuit in bipolar technology. It has an internal supply voltage limitation. With typical 150 mA ignition pulse, it is possible to determine the phase-shift of the ignition point by comparing the mains sync. ramp voltage with a preset required value. It generates a single ignition pulse per half wave; therefore, it is suitable for capacitive and inductive loads in low cost applications.

GENERAL DESCRIPTION

After the end of the zero transition pulse, Cö/t is charged from the constant current source Iö, whose value is adjusted externally with Rö at Pin 3 due to the unavoidable tolerance of Cö/t (Phase 1).
