LM26CIM5X-HHD from Texas Instruments, in a SOT-23-5. 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 | HYST | input | Hysteresis control digital input. Tie to GND to select 10°C hysteresis (typ 11°C) or to V+ to select 2°C hysteresis. |
| 2 | GND | power_in | Ground reference. Connected to the back side of the die through the lead frame; connect to system ground. |
| 3 | VTEMP | output | Analog output voltage proportional to temperature (slope approximately -10.82 mV/°C). Leave floating or connect to a high-impedance node for after-assembly system testing. |
| 4 | V+ | power_in | Positive supply input. Connect to 2.7 V to 5.5 V with a 0.1 µF bypass capacitor. Typical supply current 16 µA (max 40 µA). |
| 5 | US | output | Undertemperature Shutdown push-pull, active-HIGH thermostat digital output (HHD variant, factory trip point 0°C). Drives HIGH when die temperature falls below the preset TUS trip point. Connect to controller interrupt or system/power-supply shutdown. |
