DRV8811PWP

Texas Instruments · Stepper Motor Driver · HTSSOP-28-EP

DRV8811PWP from Texas Instruments, in a HTSSOP-28-EP. 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 ISENA input Bridge A current sense input; connect to sense resistor for winding A current control.
2 HOMEn output Home position output; logic low when stepper motor is at home state, logic high at other states.
3 DIR input Direction control input; logic level sets stepper motor stepping direction.
4 AOUT1 tri_state H-bridge output 1 for connection to bipolar stepper motor winding A.
5 DECAY input Decay mode select input requiring bypass to GND with 0.1-μF ceramic capacitor.
6 RCA input Bridge A blanking and off-time adjust node; connect parallel RC network to GND.
7 GND power_in Device ground connection.
8 VREF power_in Winding current reference voltage input for setting drive current magnitude.
9 RCB input Bridge B blanking and off-time adjust node; connect parallel RC network to GND.
10 VCC power_in Logic power supply (3-5 V) with 0.1-μF bypass capacitor to GND.
11 BOUT1 tri_state H-bridge output 1 for connection to bipolar stepper motor winding B.
12 USM1 input Microstep mode select input bit 1; with USM0 configures full/half/quarter/eighth-step resolution.
13 USM0 input Microstep mode select input bit 0; with USM1 configures full/half/quarter/eighth-step resolution.
14 ISENB input Bridge B current sense input; connect to sense resistor for winding B current control.
15 VMB power_in Bridge B motor power supply (8-38 V); must be connected to same supply as VMA.
16 SRn input Synchronous rectification enable input; active-low with internal pulldown.
17 RESETn input Active-low reset input that initializes indexer logic and disables H-bridge outputs.
18 BOUT2 tri_state H-bridge output 2 for stepper motor winding B with positive current direction BOUT1→BOUT2.
19 STEP input Rising edge step input that advances stepper indexer one position.
20 VGD power_in Low-side gate drive supply with 0.22-μF bypass capacitor to GND.
21 GND power_in Device ground connection.
22 VCP power_in High-side gate drive supply requiring 0.22-μF ceramic capacitor connection to VM.
23 CP1 power_in Charge pump flying capacitor terminal; connect 0.22-μF capacitor between CP1 and CP2.
24 CP2 power_in Charge pump flying capacitor terminal; connect 0.22-μF capacitor between CP1 and CP2.
25 AOUT2 tri_state H-bridge output 2 for stepper motor winding A with positive current direction AOUT1→AOUT2.
26 ENABLEn input Active-low enable input; logic high disables device outputs.
27 SLEEPn input Sleep mode input; logic low enters low-power sleep mode.
28 VMA power_in Bridge A motor power supply (8-38 V); must be connected to same supply as VMB.
29 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
