MAX6683AUB+ from Maxim Integrated, 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	1.8VIN	input	Analog input that monitors the 1.8V nominal supply; voltages greater than 6V must be attenuated with an external resistive voltage divider.
2	2.5VIN	input	Analog input that monitors the 2.5V nominal supply; voltages greater than 6V must be attenuated with an external resistive voltage divider.
3	5VIN	input	Analog input that monitors the 5V nominal supply; voltages greater than 6V must be attenuated with an external resistive voltage divider.
4	N.C.	unconnected	Not internally connected; the datasheet recommends connecting this pin to GND to improve thermal conductivity.
5	GND	power_in	Ground reference; all voltages on the device are referenced to this pin.
6	ALERT	output	Open-drain SMBus alert (interrupt) output that signals a temperature or voltage limit violation and is active low.
7	ADD	input	SMBus/I2C address select input, sampled at the beginning of each transaction; its connection to GND, SDA, SCL, or VCC sets the 2 LSBs of the slave address.
8	SDA	bidirectional	SMBus/I2C-compatible serial data line.
9	SCL	input	SMBus/I2C-compatible serial clock input.
10	VCC	power_in	Supply voltage input from +2.7V to +5.5V that also serves as a voltage monitor input; bypass to GND with a 0.1µF capacitor.
