GC7780AD

Sungine · Human Body Sensing Sensor · DIP-16

GC7780AD from Sungine, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A input Repeat-trigger control: A=1 allows retriggering, A=0 gives non-retriggerable operation (input high min 3.5V, low max 1.5V at VDD=5V).
2 VO output Control signal output that goes high on a valid trigger (rising edge of VS) and stays low outside delay time TX and when there is no VS rising edge.
3 RR1 passive Output delay time TX adjustment terminal with R1, where TX ≈ 49152·R1·C1.
4 RC1 passive Output delay time TX adjustment terminal with C1, where TX ≈ 49152·R1·C1.
5 RC2 passive Trigger lockout time Ti adjustment terminal with C2, where Ti ≈ 24·R2·C2.
6 RR2 passive Trigger lockout time Ti adjustment terminal with R2, where Ti ≈ 24·R2·C2.
7 VSS power_in Negative supply terminal, normally connected to 0V.
8 VRF/RESET input Reference voltage and reset input, normally tied to VDD; taking it to 0 resets the timers.
9 VC input Trigger inhibit input: triggering is inhibited when VCVR, with VR≈0.2VDD.
10 IB passive Op-amp bias current setting terminal, connected to VSS through RB of about 1MΩ.
11 VDD power_in Positive supply terminal, range 3 to 12V.
12 2OUT output Output of the second-stage operational amplifier.
13 2IN- input Inverting input of the second-stage operational amplifier.
14 1IN+ input Non-inverting input of the first-stage operational amplifier.
15 1IN- input Inverting input of the first-stage operational amplifier.
16 1OUT output Output of the first-stage operational amplifier.
