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 repeatable triggering; A='0' selects non-repeatable trigger mode. VAH >= 3.5 V, VAL <= 1.5 V at VDD=5V. |+| 2 | VO | output | Control signal output. Driven high on a valid trigger (VS rising edge) and remains 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 adjustment pin. External resistor R1 to RC1/capacitor C1 sets Tx ≈ 67025 * R1 * C1. |+| 4 | RC1 | passive | Output delay time Tx adjustment pin. Works with RR1 and external RC network to set delay period Tx. |+| 5 | RC2 | passive | Trigger blocking time Ti adjustment pin. External RC with RR2 sets Ti ≈ 60 * R2 * C2. |+| 6 | RR2 | passive | Trigger blocking time Ti adjustment pin. Works with RC2 to set the blocking period after Tx expires. |+| 7 | VSS | power_in | Negative supply / ground. Typically tied to 0 V. |+| 8 | VRF/RESET | input | Reference voltage and reset input. Normally tied to VDD; driving this pin to '0' resets the internal timers. |+| 9 | VC | input | Trigger inhibit input. Triggering is inhibited when VC < VR (~0.2*VDD) and enabled when VC > VR. Commonly driven by a CdS photocell for ambient-light gating. |+| 10 | IB | passive | Op-amp bias current setting pin. Connect an external resistor RB (~1 MΩ) from IB to VSS to set the internal op-amp bias. |+| 11 | VDD | power_in | Positive supply input. Operating range 3.0 to 5.0 V; absolute maximum +6 V. |+| 12 | 2OUT | output | Second-stage internal op-amp (OP2) output. Feeds the bidirectional amplitude discriminator (COP1/COP2). |+| 13 | 2IN- | input | Second-stage op-amp (OP2) inverting input. Typically connected to 2OUT through a feedback network and AC-coupled from 1OUT via C4. |+| 14 | 1IN+ | input | First-stage op-amp (OP1) non-inverting input. Typically driven from the pyroelectric PIR sensor output. |+| 15 | 1IN- | input | First-stage op-amp (OP1) inverting input. Used with an external RC feedback network to set OP1 gain. |+| 16 | 1OUT | output | First-stage op-amp (OP1) output. AC-coupled to OP2 via C4 for second-stage amplification. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOP-16 |+| Category | Sensor |+| Pins | 16 |++## Ordering variants++- `BISS0001DRG`+- `BISS0001DRGPG`+- `BISS0001DRGPWRG`++## CAD (KiCad official)++- Symbol: `BISS0001DRG`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor datasheet](docs/biss0001drg-datasheet.pdf) (10 pp, sha256 `a73355c54bc97db2`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
