MC145010P

The CMOS MC145010 is an advanced smoke detector component containing sophisticated very-low-power analog and digital circuitry.The variable-gain photo amplifier allows direct interface to IR detectors (photodiodes).Two external capacitors,C1 and C2,C1 being the larger,determine the gain settings.Low gain is selected by the IC during most of the standby state.The MC145010P belongs to MC145010 series.

Features of the MC145010P are:(1)circuit is designed to operate in smoke detector systems that comply with UL217 and UL268 specifications;(2)operating voltage range: 6 to 12 V;(3)operating temperature range: -10 to 60;(4)average supply current: 12 A;(5)power-on reset places IC in standby mode (non-alarm state);(6)electrostatic discharge (ESD) and latch up protection circuitry on all pins;(7)chip complexity: 2000FETs,12NPNs,16 resistors,and 10 capacitors;(8)ideal for battery powered applications.
