LM56CIMMX from Texas Instruments, in a VSSOP-8. 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 | VREF | power_in | 1.250V bandgap voltage reference output that should source a 50 µA load to maintain trip point accuracy. |
| 2 | VT2 | input | Input for the temperature trip point voltage for OUT2, within GND to V+ − 1 V. |
| 3 | VT1 | input | Input for the temperature trip point voltage for OUT1, within GND to V+ − 1 V. |
| 4 | GND | power_in | Ground pin. |
| 5 | VTEMP | output | Temperature sensor output of +6.20 mV/°C x T + 395 mV with a maximum output impedance of 1500 Ω. |
| 6 | OUT2 | output | Open collector active-LOW digital output that goes LOW above the T2 set point and HIGH below T2 − 5°C, not intended to directly drive a fan motor. |
| 7 | OUT1 | output | Open collector active-LOW digital output that goes LOW above T1 and HIGH below T1 − 5°C, not intended to directly drive a fan motor. |
| 8 | V+ | power_in | Positive supply voltage pin, 2.7V to 10V, to be bypassed with a 0.1 µF capacitor to ground. |
