LMC7221AIM5 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 | OUTPUT | output | Open-drain comparator output that only pulls low and needs an external pull-up resistor, which can go to a voltage up to 15V above or below the supply; rated for 15V at the pin and ±30mA. |
| 2 | V+ | power_in | Positive supply pin, operating range 2.7V to 15V (16V absolute maximum between V+ and V−). |
| 3 | NON-INVERTING INPUT | input | Non-inverting (+) comparator input with a common-mode range that extends beyond both V− and V+, limited to V+ +0.3V and V− −0.3V. |
| 4 | INVERTING INPUT | input | Inverting (−) comparator input with a common-mode range that extends beyond both V− and V+, limited to V+ +0.3V and V− −0.3V. |
| 5 | V- | power_in | Negative supply pin, normally connected to ground (0V) in single-supply operation. |
