Product details
Overview
DRV8837CDSGT from Texas Instruments is a 1-A, low-voltage H-bridge motor driver IC designed for battery-powered motion control. It integrates N-channel power MOSFETs (HS + LS RDS(ON) = 1 Ω), supports 0–11 V motor supply (VM), operates with 1.8–7 V logic supply (VCC), and features standard PWM (IN1/IN2) interface for brushed DC motor control in compact camera lens actuators.
For engineers reviewing the DRV8837CDSGT datasheet, DRV8837CDSGT pinout, DRV8837CDSGT application, or DRV8837CDSGT equivalent, key selection criteria include its 120-nA max sleep current, integrated overcurrent/thermal/UVLO protection, 2.0 × 2.0 mm WSON-8 package with thermal pad, and IN/IN logic mode enabling forward/reverse/brake/coast operation without external gate drivers.
Technical Context
The DRV8837CDSGT implements an internal charge pump to drive N-channel MOSFET gates, eliminating need for external high-side drivers. Its IN/IN control logic directly maps input states to H-bridge output configurations-no enable or direction pins required.
Protection is implemented via analog current limiting per FET (trip level 1.2 A), deglitch timing (1 μs), automatic retry (1 ms), and thermal shutdown at 150°C minimum. VCC UVLO activates below 1.7 V and releases above 1.8 V, while nSLEEP enables Hi-Z sleep mode with 95-nA max VM supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1 A continuous; supports typical camera lens actuator loads without external current boosting. |
| VM Supply Range | 0 to 11 V; compatible with single-cell Li-ion (up to 4.2 V), dual-cell alkaline (up to 3 V), or regulated 9-V rails. |
| VCC Supply Range | 1.8 to 7 V; allows direct connection to 3.3-V or 5-V microcontroller I/O rails without level shifting. |
| RDS(ON) (HS+LS) | 1 Ω typical at 25°C; limits conduction loss to ≤0.8 W at 0.8-A RMS load current. |
| Sleep Current | ≤95 nA on VM, ≤25 nA on VCC; enables multi-year battery life in always-on optical stabilization systems. |
| OCP Trip Level | 1.2 A minimum; provides margin above rated 1-A output while avoiding nuisance tripping during motor startup surge. |
| Thermal Shutdown | 150°C minimum activation; protects against sustained overload or poor PCB thermal design without requiring external thermal sensors. |
Pinout & Package
DRV8837CDSGT uses an 8-pin WSON (DSG) package with 2.0 × 2.0 mm body size and exposed thermal pad for enhanced power dissipation. The package is RoHS-compliant and rated for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VM | Motor power supply input | Bypassed with 0.1-µF ceramic capacitor; supplies current to H-bridge FETs; no UVLO protection. |
| VCC | Logic power supply input | Bypassed with 0.1-µF ceramic capacitor; powers internal logic and charge pump; includes 1.7-V UVLO. |
| GND | Power ground reference | Must connect to PCB ground plane; serves as return path for VM, VCC, and output currents. |
| OUT1 / OUT2 | H-bridge motor outputs | Drive motor winding terminals; support bidirectional current flow; internally protected against shoot-through. |
| IN1 / IN2 | PWM control inputs | Direct logic-level interface (1.8–5.5 V compatible); define forward/reverse/brake/coast via truth table. |
| nSLEEP | Active-low sleep enable | Pulled down internally (100 kΩ); asserts Hi-Z sleep mode when low; wake time ≤30 µs after rising edge. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Enables full N-channel H-bridge operation from single low-voltage supply-no external bootstrap components needed. |
| IN/IN Control Interface | Eliminates requirement for dedicated direction/enable pins; simplifies MCU GPIO usage and firmware state management. |
| 120-nA Max Sleep Current | Reduces standby power in portable optics to negligible levels-critical for battery-operated DSLR lens modules. |
| Per-FET Analog OCP | Detects overcurrent on high-side and low-side independently, preventing latch-up during short-circuit or stalled-motor conditions. |
| Exposed Thermal Pad | Provides low-thermal-resistance path (RθJB = 32.2°C/W) to PCB ground plane-enables 1-A operation without heatsink in space-constrained designs. |
Applications
| Camera Autofocus Actuators | DSLR Lens Positioning |
|---|---|
Use Scenario: Precise linear movement of voice-coil motor (VCM) or piezo elements in smartphone camera modules. IC Role / Device Role / Timing Role: H-bridge driver controlling bidirectional current through VCM coil to achieve sub-micron positioning accuracy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | 2-A peak output, dual-channel, 2.7–10 V VM, separate A/B enable pins, no integrated charge pump (requires external bootstrap). | Better suited for dual-motor robots; larger 20-pin SSOP package; higher quiescent current (10 µA vs 95 nA). | Select when higher current or dual-H-bridge integration is required; avoid if ultra-low sleep power or minimal footprint is critical. |
| MP6550GQZ | 1.5-A continuous, 2.5–11 V VM, 1.8–5.5 V VCC, 1.2-Ω RDS(ON), 1.5-µA sleep current, same WSON-8 footprint but different pinout. | Compatible with same PCB area but requires layout revision; lacks nSLEEP pin-uses EN pin instead. | Consider for new designs needing slightly higher current headroom; not drop-in replaceable due to pinout mismatch and missing nSLEEP functionality. |
Compared with TB6612FNG and MP6550GQZ, the DRV8837CDSGT delivers superior sleep efficiency and smallest form factor for single-motor, battery-sensitive applications-making it optimal for camera modules where every nanoamp and square millimeter matters.

FAQ
What is the maximum continuous output current rating for the DRV8837CDSGT?
The DRV8837CDSGT is rated for 1 A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Its overcurrent protection trips at a minimum of 1.2 A, providing safety margin during transient motor surges. Derating is required above 85°C ambient, and actual achievable current depends on VM voltage, PCB copper area, and airflow.
Does the DRV8837CDSGT require external components for gate driving?
No, the DRV8837CDSGT integrates an internal charge pump that generates the necessary gate-drive voltages for its N-channel H-bridge MOSFETs. This eliminates the need for external bootstrap capacitors, diodes, or high-side driver ICs-reducing BOM count and board area while simplifying layout for compact optical systems.
How does the nSLEEP pin function on the DRV8837CDSGT?
The nSLEEP pin on the DRV8837CDSGT is an active-low input that places the device into ultra-low-power sleep mode when driven logic low. In sleep mode, all H-bridge FETs are disabled (Hi-Z), and VM supply current drops to ≤95 nA. Wake time from sleep to full operation is ≤30 µs after nSLEEP transitions high, enabling rapid responsiveness in duty-cycled applications like camera autofocus.
What protection features are built into the DRV8837CDSGT?
The DRV8837CDSGT includes three core protections: VCC undervoltage lockout (UVLO) activating below 1.7 V, per-FET overcurrent protection (OCP) with 1-μs deglitch and 1-ms auto-retry, and thermal shutdown (TSD) triggering at ≥150°C die temperature. All faults disable the H-bridge outputs and recover automatically when conditions normalize-no external fault-handling circuitry required.
Is the DRV8837CDSGT pin-compatible with other members of the DRV8837 family?
Yes, the DRV8837CDSGT shares identical pinout, package (WSON-8), and functional interface with other variants in the DRV8837 family-including DRV8837CDR and DRV8837CDSGR. Differences are limited to packaging format (tape-and-reel vs. cut tape), marking, and lifecycle status-not electrical behavior or layout compatibility.
