WT8076 Datasheet | Weltrend Semiconductor

DESCRIPTION The WT8076 is a PIR controller IC which integrates amplifier, window detector and light control functions. The light can be controlled by a Relay or Triac with adjustable delay time. A CDS interface is provided to sense day time and night time. A walk-test fuction helps user while setting up the light set. The line remote control function can switch the light set between auto mode and always-on mode. FEATURES .. - Adjustable detection range - Adjustable delay time - CDS interface to differentiate night time and day time - Walk-test function - Line remote control to switch auto mode and always on mode - Relay or Triac output - High noise immunity - Low power consumption ( operating 500u A, standby 130u A, Typ. ) PIN ASSIGNMENT WT8076N16P1 UOU1 NII1 II1 VREF GND TB TCI 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 UOU2 NII2 II2 CDS VDD ZCD RELAY TRIAC WT8076S16P1 GND TB TCI TRIAC RELAY ZCD VDD 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VREF II1 NII1 UOU1 UOU2 NII2 II2 CDS WT8076N18P2 UOU1 NII1 II1 VREF GND TB TCI TRIAC 1 2 3 4 5 6 7 8 9 18 17 16 15 14 13 12 11 10 UOU2 NII2 II2 CDS VDD ND WK ZCD RELAY Ordering Information PART No. WT8076N16P1 WT8076S16P1 WT8076N18P2 PACKAGE 16 Pin P-DIP 16 Pin SOIC 18 Pin P-DIP Weltrend Semiconductor Inc. 2F, No. 24, Industry E. 9 th RD., Science-Based Industrial Park, Hsin-Chu, Taiwan TEL:886-3-5780241 FAX:886-3-5794278.5770419 eltrend Passive Infrared (PIR) Controller PIN DESCRIPTION Pin No. N16P1 S16P1 N18P1 Name 1 2 3 4 5 6 7 8 9 10 11 UOU1 NII1 II1 VREF GND TB --TCI TRIAC RELAY ZCD Descriptions Output of the first stage OP amplifier.
