TELEFUNKEN Semiconductors U 217 B / U 217 B–FP Zero Voltage Switch / Temperature Control for General Applications Technology: Bipolar Features D Direct supply from the mains D Current consumption ≤ 0.5 mA D Very few external components D Full wave drive – no d.c. current component in the load circuit D Negative output current pulse typ. 100 mA – short circuit protected D Simple power control D Ramp generator D Reference voltage Case: DIP 8, SO 8 Figure 1 Block diagram and pin connections Preliminary Information 1 U 217 B / U 217 B–FP TELEFUNKEN Semiconductors Figure 2 Typical circuit — Period group control 0 ... 100 % General Description 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. Informations regarding supply sync. is provided at Pin 8 via resistor RSync. To avoid d.c. load on the mains, full wave logic guarantee that complete mains cycles are used for load .
