MAX49925XATB+ from Maxim / Analog Device, in a TDFN-10-EP(3x3). 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	RS+	input	External resistor power-side connection input; RS+ and RS- to GND are rated -42V to +80V and RS+ to RS- is limited to ±2V.
2	RS-	input	External resistor load-side connection input; RS+ and RS- to GND are rated -42V to +80V and RS+ to RS- is limited to ±2V.
3	N.C.	unconnected	Not connected.
4	OUT	output	Current-sense output with its common-mode point at VREF; OUT to GND is rated -0.3V to VDD + 0.3V with continuous current limited to 10mA.
5	GND	power_in	Ground, serving as signal and power return.
6	VDD	power_in	Supply voltage input operating from +2.7V to +5.5V, to be bypassed to ground with a 10nF COG/NPO and 1µF X5R capacitor.
7	REF2	input	Reference input 2, which together with REF1 sets the output common-mode point VREF = (VREF1 + VREF2)/2; continuous current limited to 10mA.
8	REF1	input	Reference input 1, which together with REF2 sets the output common-mode point VREF = (VREF1 + VREF2)/2; continuous current limited to 10mA.
9	GAIN2	input	Gain selection input 2 that, together with GAIN1, selects nominal gain of 10, 20, 50 or 100 V/V.
10	GAIN1	input	Gain selection input 1 that, together with GAIN2, selects nominal gain of 10, 20, 50 or 100 V/V.
11	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
