ADM1191-2ARMZ-R7 from Analog Devices, in a MSOP-10. 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 | VCC | power_in | Positive supply input with an operating range of 3.15 V to 26 V; an undervoltage lockout circuit resets the ADM1191 when a low supply voltage is detected. |
| 2 | SENSE | input | Current sense input; the voltage across the sense resistor between VCC and SENSE is proportional to load current and is amplified before ADC digitization. |
| 3 | CONV | input | Convert start input; a high level enables an ADC conversion, and the pin should be tied high if not required so the ADC runs. |
| 4 | GND | power_in | Chip ground pin. |
| 5 | SETV | input | Overcurrent threshold input compared with the current sense amplifier output, where a lower voltage causes ALERTB to assert at a lower current level, with a typical response time of 1 µs to 2 µs. |
| 6 | SCL | input | I2C clock input that is open-drain and requires an external resistive pull-up. |
| 7 | SDA | bidirectional | I2C data input/output that is open-drain and requires an external resistive pull-up. |
| 8 | A0 | input | I2C address pin that can be tied low, tied high, left floating, or tied low through a resistor, and which sets one of sixteen addresses together with A1. |
| 9 | A1 | input | I2C address pin that can be tied low, tied high, left floating, or tied low through a resistor, and which sets one of sixteen addresses together with A0. |
| 10 | ALERTB | output | Active-low, open-drain overcurrent alert output that asserts low on an overcurrent condition, latches until cleared via the ALERT_EN register, and is rated to 30 V. |
