TCA785 - Phase Controller

General Description

The synchronization signal is obtained via a high-ohmic resistance from the line voltage (voltage V5).

A zero voltage detector evaluates the zero passages and transfers them to the synchronization register.

Key Features

  • q Reliable recognition of zero passage q Large.

TCA 785 Phase Control IC Pb-free lead plating; RoHS compliant Features q Reliable recognition of zero passage q Large application scope q May be used as zero point switch q LSL compatible q Three-phase operation possible (3 ICs) q Output current 250 mA q Large ramp current range q Wide temperature range TCA 785 Bipolar IC PG-DIP-16-1 Type TCA 785 Ordering Code Q67000-A2321 Package PG-DIP-16-1 This phase control IC is intended to control thyristors, triacs, and transistors. The trigger pulses can be shifted within a phase angle between 0 ˚ and 180 ˚. Typical applications include converter circuits, AC controllers and three-phase current controllers. This IC replaces the previous types TCA 780 and TCA 780 D.
