Follow the recommended settings to control the timing, which canshorten the OPA circuit stability time and reduce the average current.

HT45F24A OPA GBW is up to 3.5MHz, the signal response speed is fast, and the detection time can be shortened to <100s.

The receiver sensor needs a metal shield cover and ground for isolation. The sensor signal is weak, therefore several special PCB Layout notes

must be taken into account. The Sensor input pin should be as close to the MCU OPA inputs as possible

and use as few through holes (Vias) as possible. It is recommend to use double-sided PCBs and have good ground shielding. As A1P is pin-shared with PA2, it should avoid extra wires.

(OPA1 can be interchanged with OPA2.)

Smoke Alarm Smoke Alarm ‒‒ Shortened OPA Circuit Shortened OPA Circuit Stability TimeStability Time

CH1 : IR LED transmit signalCH2 : second stage OPA output signal

Uses external OPA for power control. When the OPA is enabled an obvious rising signal will emerge with a stability time of about 2 ~ 5ms.

CH1 : IR LED transmit signalCH2 : second stage OPA output signal

The HT45F24A OPA can be set by the application program to enable the two stage OPAs in order, which can shorten the circuit stability time to 0.5 ~ 1ms and reduce the average current.

LED consumption is not added to the total current, because only when smoke is detected or when the test key is activated is the LED on.4. The regular alarm test current is not added to the total current.
