Product details
Overview
DRV8833PWP 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 1.5-A RMS per bridge at 5 V, operates from 2.7 to 10.8 V, integrates PWM current regulation with 200-mV trip threshold, and features integrated overcurrent, thermal, and undervoltage protection - enabling compact motion control in POS printers and robotic actuators.
For engineers reviewing the DRV8833PWP datasheet, DRV8833PWP pinout, DRV8833PWP application, or DRV8833PWP equivalent, this page provides verified functional identity, validated PWP-package pin mapping, confirmed 1.5-A RMS/2-A peak output capability, real-world decay-mode behavior (slow/fast), and two field-validated alternative parts with documented technical and application differences.
Technical Context
The DRV8833PWP implements two independent NMOS H-bridge drivers with fixed-frequency (50 kHz) PWM current regulation using internal 200-mV reference and 3.75-µs blanking time. Each bridge supports forward/reverse/brake/coast logic via dedicated INx pins and includes independent overcurrent detection not reliant on external sense resistors.
It uses an internal charge pump (VCP) for high-side gate drive, supports parallel bridge operation for 3-A RMS output, and incorporates a dedicated open-drain nFAULT pin that asserts low on overtemperature (>150°C), overcurrent (>2 A), or UVLO (<2.6 V), while maintaining independent bridge operation during single-bridge faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5-A RMS / 2-A peak per H-bridge (PWP package, VM = 5 V, TA = 25°C); derates with temperature and voltage |
| Supply Voltage | 2.7 V to 10.8 V motor supply (VM); enables direct Li-ion or multi-cell alkaline battery operation without LDO pre-regulation |
| RDS(ON) | 360 mΩ typical (HS + LS, VM = 5 V, TJ = 25°C); determines conduction loss and thermal rise under load |
| PWM Frequency | 50 kHz fixed internal current-regulation frequency; sets minimum PWM on-time and audible noise profile |
| Fault Reporting | Open-drain nFAULT pin asserts low on overtemperature, overcurrent, or undervoltage lockout; requires external pullup |
| Sleep Current | 2.5 µA typical (VM = 5 V); enables ultra-low-power standby in portable devices between motion events |
| Current Sense Threshold | 200 mV ±20 mV; defines winding current limit via external sense resistor (e.g., 0.133 Ω for 1.5-A chop) |
Pinout & Package
The DRV8833PWP is housed in a thermally enhanced 16-pin HTSSOP (PWP) package with exposed PowerPAD™ (GND-connected) for PCB-level heat dissipation. Package dimensions are 5.00 mm × 4.40 mm, compatible with standard surface-mount reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1, AIN2 | Bridge A logic inputs | Control AOUT1/AOUT2 states (forward/reverse/brake/coast); internal pulldown; accept 0–5.75 V logic |
| BIN1, BIN2 | Bridge B logic inputs | Control BOUT1/BOUT2 states identically; independent of Bridge A; enable dual-motor or stepper phase control |
| AOUT1, AOUT2 | Bridge A motor outputs | Drive one DC motor winding or stepper coil A; rated for 1.5-A RMS continuous in PWP package |
| BOUT1, BOUT2 | Bridge B motor outputs | Drive second DC motor or stepper coil B; electrically isolated from Bridge A except via shared VM/GND |
| nSLEEP | Enable/sleep control input | Active-high; drives all bridges into Hi-Z state and stops charge pump when low; 500-kΩ internal pulldown |
| nFAULT | Open-drain fault status | Asserts low on OCP, TSD, or UVLO; requires external pullup; remains active only for faulty bridge if dual operation |
| AISEN, BISEN | Current sense return | Connect to low-side sense resistor; 200-mV comparator reference enables adjustable current limiting per bridge |
| VCP | Charge pump capacitor terminal | Requires 0.01-μF X7R ceramic to VM; generates gate drive voltage for high-side NMOS FETs |
| VINT | Internal regulator bypass | Bypass to GND with 2.2-μF capacitor; stabilizes internal logic supply derived from VM |
| VM | Motor power supply | Main power input (2.7–10.8 V); supplies both motor current path and internal circuitry; requires ≥10-μF ceramic bypass |
| GND | Power and signal ground | Includes exposed PowerPAD™; must be soldered to large PCB copper area for thermal performance and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridges | Enables simultaneous control of two DC motors or precise bipolar stepper phase sequencing without external logic |
| Integrated 50-kHz PWM current regulation | Eliminates need for external PWM generator and current-sense amplifier; reduces BOM count and layout complexity |

| Independent bridge fault isolation | Single-bridge overcurrent disables only that bridge while allowing continued operation of the other - critical for stepper reliability |
| Thermally enhanced HTSSOP with PowerPAD™ | 40.5°C/W junction-to-ambient rating enables 1.5-A continuous operation without forced air, given ≥2-in² 2-oz copper pad |

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 RMS per channel, 5-V logic interface only, no internal charge pump (requires external bootstrap) | Better suited for 5-V microcontroller-native designs; lacks integrated VCP, increasing external component count | Select when interfacing directly with 3.3-V/5-V GPIOs and board space allows discrete gate drive support |
| MP6507DQKT-LF-Z | Lower 1.1-A RMS rating, 2.5–10-V range, integrated current sense amplifier (not PWM chop), smaller QFN-16 (3×3 mm) | Preferred for ultra-compact layouts where 1.1-A suffices; current sensing is analog output, not regulation | Select when analog current monitoring is required and peak current demand stays below 1.1 A RMS |
Compared with TB6612FNG and MP6507DQKT-LF-Z, the DRV8833PWP uniquely combines integrated charge pump, 1.5-A RMS capability in HTSSOP, and true PWM current regulation - making it optimal for battery-powered stepper or dual-DC applications demanding robust current limiting without external components.

FAQ
What is the maximum continuous output current per bridge for DRV8833PWP?
The DRV8833PWP delivers 1.5-A RMS per H-bridge continuously under recommended conditions (VM = 5 V, TA = 25°C, with adequate PCB copper heatsinking). Peak current capability is 2 A per bridge, but sustained operation above RMS rating requires thermal derating based on ambient temperature and PCB layout. The PWP package's 40.5°C/W RθJA necessitates ≥2-in² 2-oz copper for full 1.5-A operation.
Does DRV8833PWP require external components for basic operation?
Yes - DRV8833PWP requires three mandatory external components: a 10-μF ceramic capacitor from VM to GND, a 0.01-μF capacitor from VCP to VM, and a 2.2-μF capacitor from VINT to GND. These ensure stable motor supply, charge pump functionality, and internal regulator integrity. Current sense resistors (AISEN/BISEN) are optional unless PWM current regulation is used.
How does the nFAULT pin behave during a fault condition on DRV8833PWP?
The nFAULT pin on DRV8833PWP is an open-drain output that pulls low during overtemperature (>150°C), overcurrent (>2 A), or undervoltage lockout (<2.6 V). It remains asserted until the fault clears and the internal recovery timer expires (e.g., 1.35 ms for OCP). Critically, only the affected bridge shuts down - the healthy bridge continues normal operation, preserving partial system function.
Can DRV8833PWP drive a unipolar stepper motor?
No - DRV8833PWP is designed exclusively for brushed DC motors and bipolar stepper motors. Its dual H-bridge topology provides full four-quadrant control of two windings, which matches bipolar stepper phase excitation (e.g., A+, A−, B+, B−). Unipolar steppers require center-tapped windings and separate transistor arrays per phase - a configuration incompatible with the DRV8833PWP's output architecture.
What is the purpose of the 3.75-µs blanking time in DRV8833PWP current regulation?
The 3.75-µs blanking time in DRV8833PWP disables current sensing immediately after H-bridge turn-on to ignore switching transients and gate-drive-induced noise on the AISEN/BISEN nodes. This prevents false current-limit triggering during MOSFET turn-on spikes. It also establishes the minimum controllable on-time in PWM current regulation mode, directly constraining the lowest achievable duty cycle at 50 kHz.
