**Texas Instruments** · Comparators · VSSOP-10-0.5mm

INA300AIDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | IN+ | input | Analog input; connect to the supply side of the shunt resistor. |
| 2 | IN- | input | Analog input; connect to the load side of the shunt resistor. |
| 3 | LIMIT | input | Analog alert threshold limit input that sets the current-limit threshold, as described in Setting The Current-Limit Threshold. |
| 4 | ENABLE | input | Digital input that selects enable or disable mode. |
| 5 | ALERT | output | Active-low, open-drain digital output that signals an overlimit condition. |
| 6 | LATCH | input | Digital input that selects transparent or latch mode for the alert output. |
| 7 | DELAY | input | Digital input that selects the response time. |
| 8 | GND | power_in | Analog ground. |
| 9 | VS | power_in | Power supply input, 2.7 V to 5.5 V. |
| 10 | HYS | input | Digital input that sets the hysteresis, as described in Selectable Hysteresis. |
