DRV8833CPWPR

Texas Instruments · Stepper Motor Driver · TSSOP-16-EP

DRV8833CPWPR from Texas Instruments, in a TSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	nSLEEP	input	Logic high enables the device; logic low puts device into low-power sleep mode; has internal pulldown resistor (typ. 500 kΩ) and 6.5 V clamp.
2	AOUT1	output	H-bridge A output; positive current flows AOUT1 → AOUT2.
3	AISEN	output	Bridge A current-sense pin; external sense resistor to GND sets the PWM current-regulation trip level (VTRIP = 200 mV typ).
4	AOUT2	output	H-bridge A output; positive current flows AOUT1 → AOUT2.
5	BOUT2	output	H-bridge B output; positive current flows BOUT1 → BOUT2.
6	BISEN	output	Bridge B current-sense pin; external sense resistor to GND sets the PWM current-regulation trip level (VTRIP = 200 mV typ).
7	BOUT1	output	H-bridge B output; positive current flows BOUT1 → BOUT2.
8	nFAULT	output	Open-drain fault-indication output, pulled logic low during an overcurrent, thermal-shutdown or reported fault condition; requires an external pullup resistor (>1 kΩ).
9	BIN1	input	H-bridge B PWM control input; sets state of BOUT1/BOUT2 per H-bridge logic table; internal pulldown.
10	BIN2	input	H-bridge B PWM control input; sets state of BOUT1/BOUT2 per H-bridge logic table; internal pulldown.
11	NC	unconnected	No internal connection; leave unconnected or tie as needed for layout.
12	VM	power_in	Motor/power supply input, 2.7 V to 10.8 V; bypass to GND with a 10-µF ceramic capacitor rated for VM.
13	GND	power_in	Device ground; both the GND pin and the PowerPAD must be connected to ground.
14	VINT	power_out	Internal 3.3-V regulator output (3.0-3.6 V typ 3.3 V); bypass to GND with a 2.2-µF, 6.3-V capacitor; not intended to drive external loads.
15	AIN2	input	H-bridge A PWM control input; sets state of AOUT1/AOUT2 per H-bridge logic table; internal pulldown.
16	AIN1	input	H-bridge A PWM control input; sets state of AOUT1/AOUT2 per H-bridge logic table; internal pulldown.
17	GND (PowerPAD)	power_in	Exposed thermal pad; must be soldered to the PCB ground plane and connected to GND for proper thermal and electrical performance.
