Product details
Overview
DRV8833CPWP from Texas Instruments is a dual H-bridge motor driver IC designed for brushed DC or bipolar stepper motor control in space-constrained, battery-powered systems. It delivers 0.7-A RMS per bridge at 5 V, features integrated PWM current regulation (200 mV trip threshold), 1735 mΩ typical total RDS(ON), and operates across 2.7–10.8 V supply range - enabling use in portable printers, security cameras, and robotics.
For engineers reviewing the DRV8833CPWP datasheet, DRV8833CPWP pinout, DRV8833CPWP application, or DRV8833CPWP equivalent, key selection considerations include its HTSSOP-16 PowerPAD™ package thermal performance (RθJA = 40.5°C/W), sleep mode current (1.6 µA), fault reporting via open-drain nFAULT, and compatibility with external PWM speed control while retaining internal current limiting.
Technical Context
The DRV8833CPWP integrates two independent PMOS-NMOS H-bridges with fixed 20-µs off-time current chopping, using external sense resistors (AISEN/BISEN) referenced to a 200-mV internal comparator. Each bridge supports forward/reverse/brake/coast states via dual logic inputs (AIN1/AIN2, BIN1/BIN2) and enables slow-decay or fast-decay operation depending on input sequencing.
It includes comprehensive protection: VM undervoltage lockout (2.6 V trip), cycle-by-cycle overcurrent detection (1-A peak trip), and thermal shutdown (150°C). The device enters low-power sleep mode when nSLEEP is pulled low, disabling all outputs and reducing supply current to 1.6 µA - with 155-µs wake-up latency before output transition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10.8 V - supports single-cell Li-ion, 3×AA, or 9-V battery systems without external regulators. |
| Output Current (RMS) | 0.7 A per H-bridge at 5 V, 25°C - sufficient for small stepper motors (e.g., NEMA 8) or dual 12-V DC gearmotors. |
| Total RDS(ON) | 1735 mΩ typical (HS + LS) at 5 V, 25°C - limits conduction loss to ≤0.85 W per bridge at 0.7-A RMS. |
| Current Sense Threshold | 200 mV nominal - sets precise winding current limit (e.g., 200 mA with 1-Ω sense resistor). |
| Sleep Mode Current | 1.6 µA at 5 V - enables multi-year battery life in always-on portable devices during idle periods. |
| Fault Reporting | Open-drain nFAULT pin - asserts low on UVLO, OCP, or TSD; requires external pullup for system-level fault monitoring. |
| Thermal Resistance | RθJA = 40.5°C/W (HTSSOP-16) - allows 1.4-W continuous power dissipation with 25°C ambient and PCB copper pour. |
Pinout & Package
DRV8833CPWP uses the 16-pin HTSSOP (PWP) package with exposed PowerPAD™ thermal pad (5.00 × 6.40 mm body size), requiring solder connection of the pad to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1 / AIN2 | H-bridge A control inputs | Dual logic-level inputs defining AOUT1/AOUT2 state (forward/reverse/brake/coast); internal pulldown ensures safe default. |
| BIN1 / BIN2 | H-bridge B control inputs | Functionally identical to AIN1/AIN2 for second bridge; enables independent or parallel motor control. |
| AISEN / BISEN | Current sense inputs | Accept voltage drop across external shunt resistors to enable 20-µs fixed-off-time PWM current regulation. |
| AOUT1 / AOUT2 / BOUT1 / BOUT2 | H-bridge outputs | High-current terminals driving motor windings; support bidirectional current flow with integrated body diodes. |
| nSLEEP | Enable/sleep control | Active-high logic input; pulling low disables all bridges and reduces supply current to 1.6 µA. |
| nFAULT | Fault status indicator | Open-drain output asserted low during UVLO, overcurrent, or thermal shutdown; requires external pullup. |
| VINT | Internal 3.3-V regulator output | Provides regulated supply for internal logic; must be bypassed with 2.2-µF ceramic capacitor to GND. |
| VM | Motor power supply input | Primary high-current input (2.7–10.8 V); requires 10-µF ceramic bulk capacitor placed adjacent to pin. |
| GND | Power and signal ground | Common reference for VM, VINT, logic, and motor return; PowerPAD™ must be soldered to GND plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridges | Enables simultaneous control of two DC motors or one bipolar stepper motor without external gate drivers. |
| Integrated 20-µs constant-off-time current regulation | Eliminates need for external current-sense amplifier and PWM controller; supports precise torque/stall current limiting. |
| Low quiescent current sleep mode | 1.6 µA at 5 V allows battery-powered devices to maintain long standby life while retaining fast wake-up (<160 µs). |
| Comprehensive fault protection | Independent per-bridge overcurrent detection, thermal shutdown (150°C), and VM undervoltage lockout (2.6 V) prevent damage under fault conditions. |
| HTSSOP-16 PowerPAD™ package | 5.00 × 6.40 mm footprint with exposed thermal pad delivers 40.5°C/W junction-to-ambient resistance for compact thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | Higher 1.2-A peak current, 2.5–13.5 V range, separate VCC logic supply required. | Better suited for 12-V robotics where higher torque is needed; lacks integrated VINT regulator. | Select TB6612FNG when >0.7-A RMS per bridge is required and board space allows dual-supply routing. |
| MP6532GQ-Z | 0.6-A RMS per bridge, 2.7–10.5 V, smaller 3×3 mm QFN package, no VINT regulator. | Optimized for ultra-compact wearables or drones where footprint is critical and lower current suffices. | Choose MP6532GQ-Z only if thermal budget permits higher RDS(ON) and system lacks 3.3-V rail for logic. |
Compared with TB6612FNG and MP6532GQ-Z, the DRV8833CPWP uniquely combines integrated 3.3-V VINT regulation, 0.7-A RMS capability in HTSSOP-16, and 1.6-µA sleep current - making it optimal for cost-sensitive, battery-powered mechatronic systems requiring moderate torque and minimal external components.

FAQ
What is the maximum continuous output current per bridge for DRV8833CPWP?
The DRV8833CPWP delivers 0.7-A RMS per H-bridge continuously at 5 V and 25°C ambient temperature. This rating assumes proper PCB thermal design with the PowerPAD™ soldered to a ground plane. At lower VM voltages (e.g., 2.7 V), RDS(ON) increases and current capability decreases due to higher conduction losses - refer to the datasheet's thermal derating curves for precise limits at elevated temperatures or reduced supply voltages. The DRV8833CPWP also supports 1-A peak current per bridge for short durations.
How does the current regulation function work on DRV8833CPWP?
The DRV8833CPWP implements fixed 20-µs off-time PWM current regulation using an internal 200-mV comparator. When current through the motor winding reaches the threshold set by the sense resistor (ICHOP = 0.2 V / RSENSE), the bridge disables for 20 µs before re-enabling. This chopper action limits RMS current without requiring external controllers. The DRV8833CPWP maintains this regulation even during external PWM speed control - unless AISEN/BISEN pins are tied directly to GND to disable it.
Can DRV8833CPWP drive a stepper motor in parallel mode?
Yes, the DRV8833CPWP supports parallel mode by connecting AOUT1 to BOUT1 and AOUT2 to BOUT2, effectively doubling current capacity to 1.4-A RMS. Its internal dead time prevents shoot-through between bridges, eliminating timing-matching concerns. In this configuration, both bridges share the same control inputs (AIN1=BIN1, AIN2=BIN2) and sense resistor (AISEN=BISEN), simplifying firmware and layout. The DRV8833CPWP datasheet provides verified schematic guidance for safe parallel implementation.
What protection features are built into DRV8833CPWP?
The DRV8833CPWP includes three core protections: VM undervoltage lockout (UVLO) triggers at 2.6 V to prevent erratic operation; cycle-by-cycle overcurrent protection (OCP) detects >1-A peak per FET and asserts nFAULT after 2.3 µs deglitch; and thermal shutdown (TSD) disables outputs at 150°C junction temperature, resuming automatically after 20°C hysteresis. All protections operate independently per bridge and do not rely on external sense resistors - ensuring robustness even if AISEN/BISEN are unconnected.
Is DRV8833CPWP pin-compatible with other packages in the DRV8833C family?
No, DRV8833CPWP (HTSSOP-16) is not pin-compatible with the DRV8833CRTE (QFN-16) variant. Although both share identical electrical functionality and logic-level pin assignments, their physical pinouts differ: for example, GND is pin 13 in PWP but pin 11 in RTE, and nSLEEP is pin 1 in PWP but pin 15 in RTE. Layout redesign is required when switching packages. Always verify pin mapping against the specific package's datasheet diagram - the DRV8833CPWP pinout is fixed to the HTSSOP-16 configuration shown in Figure 1 of SLVSCP9.
