ADM1176-1ARMZ-R7

Analog Devices · Pre-ordered Chips · MSOP-10

ADM1176-1ARMZ-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 device when a low supply voltage is detected.
2 SENSE input Current sense input where the 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 an internal comparator trip threshold of 1.3 V that enables hot swap operation.
4 GND power_in Chip ground pin.
5 TIMER passive Timer pin where an external capacitor sets a 270 ms/µF initial timing cycle delay and a 21.7 ms/µF fault delay, and GATE turns off when TIMER is pulled beyond the upper threshold.
6 SCL input I2C clock pin, an open-drain input that requires an external resistive pull-up.
7 SDA bidirectional I2C data I/O pin, open-drain, that 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 together with A1 selects one of sixteen I2C addresses.
9 A1 input I2C address pin that can be tied low, tied high, left floating, or tied low through a resistor, and together with A0 selects one of sixteen I2C addresses.
10 GATE output High-side gate drive for the external N-channel FET, using a charge pump with a 12.5 µA pull-up current, which regulates the load current to 100 mV across the sense resistor by modulating the gate.
