GENERAL DESCRIPTION
The M75210 is a very low-power IC providing all of the required features for a photoelectric type smoke detector.
It is designed for operate at supply voltage as low as 2.
7V and suited to 3V Lithium battery powered application.
A variable-gain photo amplifier can be directly interfaced to an infrared emitter / detector pair.
The amplifier gain levels are determined by two external capacitors that are then internally selected depending on the operating mode.
Low gain is selected during standby.
During a local alarm this low gain is increased (internally) by ~ 10% to reduce fa...
