INA200AIDR from Texas Instruments, in a SOIC-8. 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 | VS | power_in | Analog power supply input, 2.7 V to 18 V. Quiescent current up to 1800 uA (max). Bypass with a 0.1 uF ceramic capacitor close to the pin. |
| 2 | OUT | output | Analog voltage output proportional to the shunt voltage times the fixed gain (20 V/V for INA200A). Output can swing rail-to-rail within specified swing limits; drives loads down to the specified minimum resistance. |
| 3 | CMPIN | input | Non-inverting comparator input. Typically driven by a resistor divider from OUT to set the current trip threshold against the internal 0.6 V reference. |
| 4 | GND | power_in | Device ground reference for the current-shunt monitor amplifier and the comparator/reference block. |
| 5 | RESET | input | Active-low comparator latch reset input. Tie low (or leave floating) to run the comparator in transparent (non-latched) mode; drive high to enable latching of the comparator output after a trip event. |
| 6 | CMPOUT | output | Open-drain comparator output. Pulls low when the CMPIN voltage exceeds the 0.6 V internal reference (over-current alert). Requires an external pull-up resistor to the desired logic rail. |
| 7 | VIN- | input | Inverting current-shunt monitor input. Connect to the low-side (load-side) terminal of the external sense resistor. Common-mode range -16 V to +80 V independent of VS. |
| 8 | VIN+ | input | Non-inverting current-shunt monitor input. Connect to the high-side (bus-side) terminal of the external sense resistor. Common-mode range -16 V to +80 V independent of VS. |
