BL59A10/BL59S10 PHOTOELECTRIC SMOKE DETECTOR IC 1. Product description 1.1. Basic function: BL59A10/BL59S10 is a CMOS LSI used for smoke detection. Ultra-low power analog and digital circuits are contained in it. Combined with an IR photoelectric chamber, this IC is used to detect smoke through receiving light scattered by tiny smoke particles going into the chamber. When smoke is detected, A burst of alarm sounds are generated by an external piezoelectric buzzer driven by the push-pull output of this IC. 1.2. Applications: Smoke detection system. 2. Features: Power supply range: Average supply current: Operating temperature range: 6V ～ 12V 12uA -10 ～ 60℃ Ideal for battery powered applications. 3.
