# LM26CIM5X-PHA

**Texas Instruments** · Thermostat Switches · SOT-23-5

LM26CIM5X-PHA from Texas Instruments, in a SOT-23-5. 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 | HYST | input | Hysteresis control digital input; connect to GND for 10°C hysteresis or to V+ for 2°C hysteresis. |
| 2 | GND | power_in | Power ground, 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 with a −10.82 mV/°C slope; leave floating or connect to a high-impedance node. |
| 4 | V+ | power_in | Power supply input; connect to 2.7 V to 5.5 V with a 0.1-µF bypass capacitor. |
| 5 | OS | output | Overtemperature shutdown open-drain, active-low thermostat digital output; connect to controller interrupt or system/power supply shutdown, with a pullup resistor of ≥ 10 kΩ. |
