Texas Instruments · Global Sourcing Parts · TSSOP-28-EP

DRV8829PWPR from Texas Instruments, in a TSSOP-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 CP1 bidirectional Charge pump flying capacitor; connect a 0.01-μF to 50-V capacitor between CP1 and CP2.
2 CP2 bidirectional Charge pump flying capacitor; connect a 0.01-μF to 50-V capacitor between CP1 and CP2.
3 VCP bidirectional High-side gate drive voltage; connect a 0.1-μF to 16-V ceramic capacitor and 1-MΩ resistor to VM.
4 VM power_in Bridge power supply (8.2 V to 45 V); both pins must be connected to same supply.
5 OUT1 output Bridge output 1; connect to motor winding; both OUT1 pins must be connected together on PCB.
6 ISEN bidirectional Bridge ground / current sense; connect to current sense resistor; both ISEN pins must be connected together on PCB.
7 OUT2 output Bridge output 2; connect to motor winding; both OUT2 pins must be connected together on PCB.
8 OUT2 output Bridge output 2; connect to motor winding; both OUT2 pins must be connected together on PCB.
9 ISEN bidirectional Bridge ground / current sense; connect to current sense resistor; both ISEN pins must be connected together on PCB.
10 OUT1 output Bridge output 1; connect to motor winding; both OUT1 pins must be connected together on PCB.
11 VM power_in Bridge power supply (8.2 V to 45 V); both pins must be connected to same supply.
12 VREF power_in Reference voltage for winding current set (recommended 1 V to 3.5 V); both VREF pins must be connected together on PCB.
13 VREF power_in Reference voltage for winding current set (recommended 1 V to 3.5 V); both VREF pins must be connected together on PCB.
14 GND power_in Device ground.
15 V3P3OUT output 3.3-V regulator output; bypass to GND with 0.47-μF to 6.3-V ceramic capacitor; can be used to supply VREF.
16 nRESET input Active-low reset input initializes internal logic and disables H-bridge outputs; internal pulldown.
17 nSLEEP input Sleep mode input; logic high to enable device, logic low to enter low-power sleep mode; internal pulldown.
18 nFAULT output Open-drain fault output; logic low when in fault condition (overtemperature or overcurrent).
19 DECAY input Decay mode select; low = slow decay, open = mixed decay, high = fast decay; internal pulldown and pullup.
20 PHASE input Bridge phase (direction); logic high sets OUT1 high and OUT2 low; internal pulldown.
21 ENBL input Bridge enable; logic high to enable H-bridge; internal pulldown.
22 NC unconnected Not connected.
23 I0 input Current set input bit 0; sets winding current as percentage of full-scale; internal pulldown.
24 I1 input Current set input bit 1; sets winding current as percentage of full-scale; internal pulldown.
25 I2 input Current set input bit 2; sets winding current as percentage of full-scale; internal pulldown.
26 I3 input Current set input bit 3; sets winding current as percentage of full-scale; internal pulldown.
27 I4 input Current set input bit 4; sets winding current as percentage of full-scale; internal pulldown.
28 GND power_in Device ground; PowerPAD thermal pad connection.
29 PowerPAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
