LM73C1QDDCRQ1 from Texas Instruments, in a TSOT-23-6L. 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 | ADDR | input | Address select input: one of three device addresses is selected by connecting this pin to ground, leaving it floating, or connecting it to VDD (three-level CMOS logic input). |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VDD | power_in | Power supply voltage; the recommended supply range is 2.7 V to 5.5 V. |
| 4 | SMBCLK | input | SMBus serial clock input, operating up to 400 kHz and low-pass filtered (CMOS logic input). |
| 5 | ALERT | output | Open-drain digital output that goes active whenever the measured temperature exceeds a programmable temperature limit. |
| 6 | SMBDAT | bidirectional | SMBus bidirectional open-drain serial data signal, synchronous to SMBCLK and low-pass filtered. |
