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 Symbol Description 1 A
Retriggerable & non-retriggerable mode select (A=1 : re-triggerable)
2 VO
Detector output pin (active high)
3 RR1
Output pulse width control (Tx) * See definition below
4 RC1
Output pulse width control (Tx) *
5 RC2
Trigger inhibit control (Ti) *
6 RR2
Trigger inhibit control (Ti) *
7 Vss
Ground
8 VRF
RESET & voltage reference input (Normally high. Low=reset)
9 VC
Trigger disable input (VC >0.2Vdd=enable; Vc<0.2Vdd =disabled)
10 IB
Op-amp input bias current setting
11 Vdd
Supply voltage
12 2OUT
2nd stage Op-amp output
13 2IN
- 2nd stage Op-amp inverting input
14 1IN
+ 1 st stage Op-amp non-inverting input
15 1IN
- 1 st stage Op-amp inverting input
16 1OUT
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.
