BL59S12 - PHOTOELECTRIC SMOKE DETECTOR

Download the BL59S12 datasheet PDF. This datasheet also covers the BL59A12 variant, as both devices belong to the same photoelectric smoke detector family and are provided as variant models within a single manufacturer datasheet.

Description

1.1 Basic function: BL59A12 (BL59S12) 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.

Features

  • Power supply range: 6V ～ 12V Average supply current: 8uA Operating temperature range: -10 ～ 60℃ Ideal for battery powered.

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: 6V ～ 12V Average supply current: 8uA Operating temperature range: -10 ～ 60℃ Ideal for battery powered applications. 3.
