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.
