TPMAX4644EUT+T from TECH PUBLIC, 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 | IN | input | Channel select logic input. 1.8V logic compatible (VIH ≥ 1.6V at VCC=3.3-5.5V, VIH ≥ 1.4V at VCC=1.5-3.3V). IN=1 connects COM to NO; IN=0 connects COM to NC. |
| 2 | V+ | power_in | Positive supply voltage input, 1.8V to 5.5V operating range (absolute max -0.3V to +6.5V). Quiescent current <2uA typical. |
| 3 | GND | power_in | Ground reference (0 V). |
| 4 | NC | passive | Normally-closed switch throw. Connected to COM when IN=0. Independent input or output; bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating. Signal range -0.3V to +5.5V. |
| 5 | COM | passive | Common switch pole (labeled COM(A)). Common output or input, switched to either NO or NC by the IN pin. Bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating. |
| 6 | NO | passive | Normally-open switch throw. Connected to COM when IN=1. Independent input or output; bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating. Signal range -0.3V to +5.5V. |
