ADM1176-2ARMZ-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 16.5 V; an undervoltage lockout circuit resets the ADM1176 when a low supply voltage is detected. |
| 2 | SENSE | input | Current sense input; a sense resistor between VCC and SENSE sets the analog current limit, and the hot swap operation keeps (VCC − VSENSE) at or below 100 mV. |
| 3 | ON | input | Active-high undervoltage input with a 1.3 V trip threshold that enables hot swap operation, and an external divider from VCC to GND can set the enable voltage. |
| 4 | GND | power_in | Chip ground pin. |
| 5 | TIMER | passive | An external capacitor sets a 270 ms/µF initial timing cycle and a 21.7 ms/µF fault delay, and the GATE pin turns off when TIMER is pulled beyond its upper threshold. |
| 6 | SCL | input | I2C clock pin that is an open-drain input and requires an external resistive pull-up. |
| 7 | SDA | bidirectional | I2C data pin that is an open-drain input/output 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, selecting 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, selecting one of sixteen addresses together with A0. |
| 10 | GATE | output | High-side gate drive for an external N-channel FET, driven by a charge pump with a 12.5 µA pull-up current, which regulates the maximum load current to 100 mV across the sense resistor by modulating the gate. |
