# KTH1701TL-TO3

**CONNTEK** · Hall Switches · TO-92S

KTH1701TL-TO3 from CONNTEK, 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, specified for 1.8 V to 5.5 V operation with a 6 V absolute maximum, and a 1 µF capacitor should be connected between VDD and GND placed as close to this pin as possible. |
| 2 | GND | power_in | Ground pin, which is the return for the supply and the reference for the 1 µF VDD decoupling capacitor. |
| 3 | OUTPUT | output | CMOS push-pull output that goes low when the field exceeds BOP and stays low until it falls below BRP, with VOL of 0.05 V typical and 0.15 V maximum and VOH of VDD-0.1 V typical at IOUT = 1 mA, and an absolute maximum output drive current of 5 mA. |
