# SL1719SH

**Slkor SLKORMICRO Elec** · Hall Switches · TO-92S

SL1719SH from Slkor SLKORMICRO Elec, in a TO-92S. 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 | VDD | power_in | Supply input, operating range 1.8 V to 5.5 V; absolute maximum supply voltage is 6 V and a 1 µF capacitor should be placed between VDD and GND, close to the VDD pin, to filter supply noise. |
| 2 | GND | power_in | Ground pin for the device; a 1 µF decoupling capacitor is connected between VDD and this ground pin. |
| 3 | OUTPUT | output | CMOS push-pull output that goes low when the applied S-pole field exceeds BOP and stays low until the field falls below BRP; output drive current is limited to 5 mA absolute maximum. |
