INA381A1QDGSRQ1
Texas Instruments · Current Sense Amplifiers · VSSOP-10-0.5mm
INA381A1QDGSRQ1 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 | Connect to the supply side of the shunt resistor; the common-mode input range is -0.2 V to +26 V and the pins withstand 26 V even with VS removed. |
| 2 | VS+ | power_in | Power supply pin with an operating range of 2.7 V to 5.5 V, bypassed with a 0.1 µF capacitor placed as close to the pin as possible. |
| 3 | ALERT | output | Active-low, open-drain over-limit alert output that should use a 10 kΩ pull-up and must not be pulled up above 5.5 V. |
| 4 | RESET | input | Digital input that selects the alert mode, with low for transparent mode and high for latch mode, and an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |
| 5 | GND | power_in | Device ground that should be connected, together with the thermal pad, to a solid ground plane on the PCB. |
| 6 | NC | unconnected | Internal connection that may be left floating, connected to ground, or connected to the supply. |
| 7 | CMPREF | input | Comparator reference input that sets the alert threshold through a resistor divider or an external reference, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |
| 8 | CMPIN | input | Comparator input signal that connects directly to VOUT when no extra hysteresis is needed, or through an external RHYS resistor to add hysteresis, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |
| 9 | VOUT | output | Current-sense amplifier output equal to the differential input voltage times the gain of 20, 50, 100, or 200 V/V, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |
| 10 | IN- | input | Connect to the load side of the shunt resistor; the common-mode input range is -0.2 V to +26 V. |
