BISS0001 Micro Power PIR Motion Detector IC =========================================== Features Low power CMOS technology (ideal for battery operated PIR devices) CMOS high input impedance operational amplifiers Bi-directional level detector / Excellent noise immunity Built-in Power up disable & output pulse control logic Dual mode : retriggerable & non-retriggerable Pin description Pin Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Symbol A VO RR1 RC1 RC2 RR2 Vss VRF VC IB Vdd 2OUT 2IN1IN+ 1IN1OUT Description Retriggerable & non-retriggerable mode select (A=1 : re-triggerable) Detector output pin (active high) Output pulse width control (Tx) * See definition below Output pulse width control (Tx) * Trigger inhibit control (Ti) * Trigger inhibit control (Ti) * Ground RESET & voltage reference input (Normally high. Low=reset) Trigger disable input (VC >0.2Vdd=enable; Vc<0.2Vdd =disabled) Op-amp input bias current setting Supply voltage 2nd stage Op-amp output 2nd stage Op-amp inverting input 1 st stage Op-amp non-inverting input 1 st stage Op-amp inverting input 1 st stage Op-amp output * Tx = The time duration during which the output pin (Vo) remains high after triggering. Ti = During this time period, triggering is inhibited. See timing charts for details. Tx ≈ 24576 xR10 x C6； Ti ≈ 24 x R9 x C7。 (ref to schematic) Absolute max. ratings Description Supply voltage Input voltage Output current Operating temperature Storage temperature Condition --- V...
