U217B-FP
Overview
Integrated circuit, U 217 B, is a triac controller for zero crossing mode. It is meant to control power in switching resistive loads of mains supply.
- Direct supply from the mains
- Current consumption ≤ 0.5 mA
- Very few external components
- Full wave drive - no d.c. current component in the load circuit
- Negative output current pulse typ. 100 mA - short circuit protected
- Simple power control
- Ramp generator
- Reference voltage Case: DIP 8, SO 8
