# KTM1311TD-ST3

**CONNTEK** · Linear Hall Sensors · SOT-23-3L

KTM1311TD-ST3 from CONNTEK, in a SOT-23-3L. 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 | Power supply input, operating from 1.8V to 5.5V per the datasheet. |
| 2 | OUTPUT | output | Push-pull CMOS output that turns on when the magnetic flux density exceeds BOPS and turns off when it falls below BRPS. |
| 3 | GND | power_in | Ground pin. |
