AF2041 from Sam wing, in a SOT-23-6. 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 | OUT | output | Touch key sense output. Drives the detection result; polarity (active-high or active-low) is selected by VGM, and behavior (direct/synchronous vs. latched/hold) is selected by TBM. Sink capability 20 mA at Vol=0.3·VDD; source capability 10 mA at Voh=0.7·VDD. |
| 2 | GND | power_in | Ground / negative supply reference. |
| 3 | KEY | input | Capacitive touch sense input. Connect through a 1 kΩ series resistor (R1, recommended 0-5 kΩ) to the touch pad. An optional CSEL capacitor (0-50 pF) to GND adjusts sensitivity; larger CSEL lowers sensitivity. Minimum detectable delta capacitance 0.2 pF. |
| 4 | VGM | input | Output polarity select. VGM tied high → OUT is active-low (idle high, asserted low on touch). VGM tied low (or floating) → OUT is active-high (idle low, asserted high on touch). Default state assumed 0 (active-high). |
| 5 | VDD | power_in | Positive supply input, 2.3 V to 5.5 V (typ 3 V). Standby current ~2.5 µA at 3 V. Decouple with a 100 nF (104) capacitor placed as close to VDD as possible. Absolute max supply -0.3 V to +5.5 V. |
| 6 | TBM | input | Hold/sync mode select. TBM tied high → OUT operates in hold (toggle/latched) mode. TBM tied low → OUT operates in synchronous (direct) mode; in this mode an internal 64 s timeout returns the output to idle. Default state assumed 0 (synchronous). |
