# AH3564Q-SA-7

**Diodes Incorporated** · Hall Sensor · SOT-23

AH3564Q-SA-7 from Diodes Incorporated, in a SOT-23. 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 | VDD | power_in | Power supply input, 3.0 V to 28 V operating range (32 V absolute max). Recommended decoupling CIN of 10 nF-100 nF to GND for stability and noise immunity. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | OUTPUT | output | Open-drain output pin, pulled low when magnetic flux density B exceeds the operate point (BOP, ±40 G typical) from either south or north pole, and released when B falls below BRP (±25 G typical). Requires an external pull-up resistor RL; internal overcurrent limit (30-55 mA) and zener clamp (28 V typical) provided. |
