The WS4518 / 4568 can replace MC145018/MC14468.

The WS4518 / 4568 is a low-power ionized smoke detector circuit that incorporates an ion chamber and a few peripheral components to forming a highly sensitive smoke detection alarm. When smoke is detected, the circuit drives an external piezo horn alarm. The circuit also has a low power supply voltage alarm and LED alarm prompts, mainly for smoke alarm system.

Its characteristics are as follows:

  • Piezoelectric Horn Driver
  • Double-sided protection output of the detection input port, dual-diode protection of the detection input port
  • Low supply voltage detection threshold internal setting, adjustable by external resistor
  • smoke detection threshold internal settings, adjustable by external resistance
  • smoke detection comparator output, built-in battery reverse polarity protection
  • Power-on reset circuit enters the static mode
  • smoke detection comparator sensitivity in line with UL217, UL268 standards
  • piezoelectric horn alarm sound in line with NFPA72, ANSi53.41 and audible emergency evacuation signal standard ISO8201
  • Package: DIP16, SOP16W
