DRV8832DRCR 概要
An H-bridge motor driver is a power management IC that uses four switching transistors arranged in an H configuration to reverse the polarity of the voltage applied to a motor, enabling forward, reverse, brake, and coast (hi-Z) operation. Within the system hierarchy, motor drivers sit between a host controller (MCU or logic) and the motor itself, translating low-current logic commands into high-current motor drive while providing protection features such as current limiting, undervoltage lockout, and thermal shutdown.
Key features include a wide operating supply range for battery-powered designs, a fixed off-time PWM current-regulation scheme that limits motor current during start-up or stall conditions, a low-power sleep mode that reduces supply current to conserve battery life, and an nFAULT output pin that signals fault conditions to a host processor. The integrated MOSFETs deliver up to 1A of continuous output current without external discrete transistors.
The DRV8832 architecture uses internal gate drive and voltage regulation so that only the motor supply and logic inputs are required externally - no external bootstrap components or gate-drive circuitry are needed. The internal current-limit regulation repeatedly disables and re-enables the bridge at a fixed off-time when the set current threshold is exceeded, holding motor torque under control during stall or acceleration events and protecting both the IC and the motor windings.
Typical applications include battery-powered toys, printers, and other low-voltage or battery-powered motion control products such as small actuators, camera lenses, locks, and consumer robotics. The low minimum supply voltage suits single-cell or dual-cell battery stacks, and the tiny 3x3 mm footprint suits space-constrained mechanisms in printers and portable devices.
A key design consideration is thermal management: at high load currents the VSON-10 package relies on its exposed pad soldered to a copper pour on the PCB to dissipate heat. Verify that the continuous motor current and the on-resistance of the internal MOSFETs keep junction temperature within limits over the full ambient range.

主な用途
DRV8832DRCR の用途: 6 件s: Battery-Powered Toys, Printer Mechanisms, Consumer Robotics, Camera Lens and Small Actuator Drive, Electronic Locks and Latches, Stepper Motor (Single Winding) Drive.
Battery-Powered Toys
The DRV8832 is explicitly designed by TI for battery-powered toy applications, where its 6.8V maximum motor supply matches typical 2-4 cell alkaline or NiMH battery stacks and its 1A output drives small DC motors for wheels, arms, and mechanisms. The integrated fixed off-time current limit is critical in toys, where motors frequently stall against obstacles; the bridge chops current automatically without firmware intervention, protecting the IC and motor windings. The nSLEEP pin reduces standby current so batteries are not drained while the toy is off, and the 3x3 mm VSON package fits compact plastic enclosures with minimal PCB area.
おすすめ
Printer Mechanisms
In inkjet and thermal printers, the DRV8832 drives DC motors for paper feed, carriage movement, and small actuators. Printer mechanisms demand accurate current control during acceleration and paper jams; the DRV8832's fixed off-time PWM regulation limits current during stalls, and the nFAULT output alerts the printer controller to fault events for user-visible error handling. The low VM rating suits 5-6V logic-derived motor rails common in desktop printers, while the 3x3 mm VSON package fits dense mainboard layouts. The integrated MOSFETs eliminate external driver transistors, reducing BOM count and assembly cost in high-volume printer production.
おすすめ
Consumer Robotics
Small consumer robots such as vacuums, toy robots, and educational platforms use the DRV8832 to drive drive wheels or small actuators from battery rails under 6.8V. The 1A continuous rating covers small gearmotor loads, and the current-limit regulation provides controlled torque during wheel stall or obstacle collision, an important safety behavior in consumer products. The single H-bridge with IN1/IN2 logic control interfaces directly to 3.3V or 5V MCU GPIO without level shifting. Thermal performance is adequate in free-air PCB layouts thanks to the exposed pad of the VSON package soldered to a copper pour.
おすすめ
Camera Lens and Small Actuator Drive
Compact optical products - camera autofocus modules, lens caps, and small latching mechanisms - require precise bidirectional DC motor drive in minimal space. The DRV8832's 3x3 mm VSON package and single H-bridge fit inside thin optical assemblies, while the 6.8V rating suits one-cell lithium or multi-cell alkaline supplies used in cameras. The current regulation prevents overstress on small lens motors during end-of-travel stops, and the nSLEEP input powers down the driver between shots to preserve battery life. The brake mode (both outputs low) provides active stopping of the motor, useful for accurate lens positioning.
おすすめ
Electronic Locks and Latches
Battery-powered smart locks and latches drive a motor briefly to actuate the locking mechanism, then remain idle - a profile that matches the DRV8832 well. The nSLEEP pin cuts driver current to near zero between operations, maximizing battery life, and the 1A current limit handles the high inrush of a motor pushing a stuck bolt without requiring external protection circuitry. The nFAULT pin reports abnormal conditions such as jams, enabling user notification. Operating from 3-6V battery stacks, the DRV8832 drives the motor directly with logic-level IN1/IN2 control from a low-power MCU with no additional gate drivers.
おすすめ
Stepper Motor (Single Winding) Drive
Per the TI datasheet, the DRV8832 can drive one winding of a stepper motor, making it usable in paired configurations for small two-phase stepper motors in instrumentation, gages, and precision positioning devices. Each DRV8832 drives one phase with its internal current regulation holding winding current at the set level, providing controlled torque without external choppers. The fixed off-time scheme runs autonomously, so a simple MCU phase sequence suffices - no sophisticated microstepping firmware is required for coarse positioning. The compact VSON package allows both phase drivers to fit beside the small stepper motor on a single PCB.

設計ノート
The VSON-10 (DRC) package relies on its exposed pad for heat dissipation. At 1A continuous drive, estimate power dissipation as I^2 x Rds(on) of the internal MOSFETs plus switching losses; solder the exposed pad to a minimum of 2x2 via-fanned copper pour on the top layer. Estimated: at 1A with typical total on-resistance in the several-hundred milliohm range, dissipation remains well under 1W, but stalled-motor conditions with current regulation cycling will raise average losses - verify junction temperature against the datasheet thermal impedance for your PCB stack-up.
Never exceed the 6.8V maximum motor supply. Battery stacks that measure 6V nominal can exceed 7V fresh off a charger or with a bench supply - add a series diode or verify worst-case battery voltage before finalizing the design. Decouple VM with a ceramic capacitor (typically 0.1uF plus bulk capacitance per datasheet recommendations) placed close to the VM pin, since motor PWM switching draws pulsed currents that cause supply droop and potential undervoltage lockout events.
Two frequent mistakes: (1) using the DRV8832 on an 8V or higher rail - it is rated only to 6.8V; TI's E2E forum directs such users to the DRV8411. (2) Assuming the DGQ (MSOP-10 PowerPAD) variant is footprint-compatible with the DRC (VSON-10) variant - the dies are the same, but the packages and pin maps differ, so PCB layouts cannot be shared. Also ensure the nSLEEP pin is actively driven at power-up; leaving it floating may leave the bridge in an undefined state until the host asserts the correct logic level.
Keep the motor output traces (OUT1/OUT2) short and wide to reduce parasitic inductance and radiated emissions from PWM switching edges. Route the nFAULT line away from motor outputs to prevent false fault signaling from inductive kick, and add a pull-up resistor to the host logic rail since nFAULT is an open-drain-style indicator - confirm the exact output structure in the TI datasheet before finalizing the pull-up value and logic polarity.
