BISS0001M

HGSEMI · Human Body Sensing Sensor · SOP-16

BISS0001M from HGSEMI, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A input Trigger mode control input. A=1 enables retriggerable mode (Vs may re-trigger Vo during Tx, extending it); A=0 selects non-retriggerable mode (Vs is ignored during Tx). VIH >= 3.5 V, VIL <= 1.5 V at VDD=5V.
2 VO output Control signal output. Driven high on the rising edge of the internal Vs trigger signal (valid trigger) and held high for the delay time Tx; otherwise low. VOH >= 4 V, VOL <= 0.4 V at VDD=5V.
3 RR1 passive Output-delay-time (Tx) adjust pin. External resistor R1 to RC1 sets Tx together with C1 per Tx ≈ 67025·R1·C1 (seconds, with R in Ω and C in F).
4 RC1 passive Output-delay-time (Tx) adjust pin. External capacitor C1 to VSS combined with R1 on RR1 sets Tx ≈ 67025·R1·C1.
5 RC2 passive Trigger-blocking-time (Ti) adjust pin. External capacitor C2 to VSS with R2 on RR2 sets Ti ≈ 60·R2·C2 (seconds, with R in Ω and C in F). During Ti any change of Vs is ignored.
6 RR2 passive Trigger-blocking-time (Ti) adjust pin. External resistor R2 to RC2 sets Ti together with C2 per Ti ≈ 60·R2·C2.
7 VSS power_in Negative supply / ground reference. Typically 0 V.
8 VRF/RESET input Reference voltage and reset input. Normally tied to VDD for normal operation; pulling to 0 resets the internal timers.
9 VC input Trigger-inhibit input. Vc < VR (≈0.2·VDD) inhibits triggering; Vc > VR enables triggering. Often driven from an LDR (e.g. CdS RGS) so ambient light disables the switch. VIH >= 1.1 V, VIL <= 0.9 V at VDD=5V.
10 IB passive Op-amp bias-current setting pin. Connect through RB (~1 MΩ) to VSS to program the internal op-amps' bias current.
11 VDD power_in Positive supply. Operating range 3.0-5.0 V (absolute max +6 V). Typical IDD 50 µA at 3 V, 100 µA at 5 V (no-load).
12 2OUT output Second-stage op-amp (OP2) output. Feeds the internal bi-directional amplitude discriminator (window comparator COP1/COP2, thresholds VH ≈ 0.7·VDD, VL ≈ 0.3·VDD).
13 2IN- input Second-stage op-amp (OP2) inverting input. AC-coupled from OP2's non-inverting input (biased to VM ≈ 0.5·VDD internally); external RC network sets the second-stage gain.
14 1IN+ input First-stage op-amp (OP1) non-inverting input. High-input-impedance signal input for the PIR sensor front-end preamplifier.
15 1IN- input First-stage op-amp (OP1) inverting input. External feedback network from 1OUT sets the first-stage gain.
16 1OUT output First-stage op-amp (OP1) output. AC-coupled through an external capacitor to the OP2 inverting input (2IN-). Open-loop gain typ. 60 dB, output swing 0.75-4.25 V at VDD=5V.
