DRV8234RTER from Texas Instruments, in a QFN-16(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 IPROPI output Analog current output proportional to load current; connect a resistor from IPROPI to ground, with IIPROPI limited to 0 to 3 mA.
2 RSVD unconnected Reserved pin; leave this pin unconnected.
3 RC_OUT output Open-drain ripple counting output, programmable over I2C as a pulse train or logic level; pull up to a 5-V or 3.3-V supply with VOD up to 5.5 V and IOD up to 5 mA.
4 nFAULT output Open-drain fault indicator, pulled low during a fault condition; requires an external pullup resistor, with VOD up to 5.5 V and IOD up to 5 mA.
5 VM power_in Motor power supply rated 4.5 V to 38 V; bypass to GND with a 0.1-µF ceramic capacitor plus sufficient bulk capacitance rated for VM.
6 OUT1 output H-bridge output connected directly to the motor, with peak output current up to 3.7 A.
7 GND power_in Device ground; connect to system ground.
8 OUT2 output H-bridge output connected directly to the motor, with peak output current up to 3.7 A.
9 A1 input I2C base address select pin, tri-level input.
10 A0 input I2C base address select pin, tri-level input.
11 nSLEEP input Sleep mode input; logic high enables the device and logic low enters low-power sleep mode, with logic input range 0 to 5.5 V and an internal pulldown resistor.
12 PH/IN2 input Controls the H-bridge output with an internal pulldown; logic input range 0 to 5.5 V.
13 EN/IN1 input Controls the H-bridge output with an internal pulldown; logic input range 0 to 5.5 V.
14 SDA bidirectional I2C data signal; requires a pullup resistor.
15 SCL input I2C clock signal.
16 VREF power_in Analog input that sets the current regulation and stall detection level; recommended VREF range 0 to 3.3 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
