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:

6V ～12V

Average supply current:

12uA

Operating temperature range:

-10 ～60℃

Ideal for battery powered applications.
