Product details
Overview
MC33886VWR2 from NXP Semiconductors (formerly Freescale) is a monolithic 5.0 A H-bridge IC for bidirectional DC motor and solenoid control, featuring integrated gate drive, charge pump, active current limiting (5.2–7.8 A), fault status reporting, and operation from 5.0 V to 40 V supply. It delivers continuous inductive load current up to 5.0 A with 120 mΩ RDS(ON) at 25 °C and supports PWM switching up to 10 kHz in automotive and industrial motion systems.
For engineers reviewing the MC33886VWR2 datasheet, MC33886VWR2 pinout, MC33886VWR2 application, or MC33886VWR2 equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative parts - all grounded in the official Freescale MC33886 Rev 10.0 datasheet and package documentation.
Technical Context
The MC33886VWR2 implements a fully protected H-bridge using SMARTMOS technology, integrating dual high-side/low-side MOSFETs with 120 mΩ typical RDS(ON), internal constant-off-time PWM current limiting, and junction-temperature-dependent foldback (ILIM drops from 6.5 A at 25 °C to 2.5 A at 175 °C). It features two independent TTL/CMOS-compatible logic inputs (IN1/IN2) and complementary disable inputs (D1 active-high, D2 active-low) that force both outputs into high-impedance state.
Fault detection includes undervoltage lockout (V+ threshold: 4.5 V ON / 4.4 V OFF), short-circuit latch-OFF (ISCH = 11 A high-side, ISCL = 8.0 A low-side), and overtemperature shutdown (TLIM = 175 °C, hysteresis = 15 °C). The open-drain Fault Status (FS) pin reports all faults with active-low assertion and requires an external 5.0 V pull-up resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A - Sustained inductive load current capability with proper heatsinking and ambient ≤125 °C. |
| RDS(ON) (per FET, 25 °C) | 120 mΩ - Enables low conduction loss and <1.2 W total I²R loss at 5 A per side. |
| Supply Voltage Range | 5.0 V to 40 V - Supports 12 V/24 V automotive and industrial rails; derated operation above 28 V. |
| PWM Frequency Support | Up to 10 kHz - Compatible with standard motor control PWM without compromising switching loss or thermal margin. |
| Active Current Limit Threshold | 5.2–7.8 A - Internally regulated foldback limit that decreases linearly above 160 °C junction temperature. |
| Fault Reporting | Open-drain FS output - Signals undervoltage, short-circuit, or overtemperature via logic-low assertion; requires external 5 V pull-up. |
| Thermal Shutdown | 175 °C with 15 °C hysteresis - Latch-OFF protection prevents device damage during sustained overload or poor heatsinking. |
Pinout & Package
MC33886VWR2 is housed in a 20-pin HSOP (Heat Sink Overmolded Package) with exposed copper thermal pad (package code: VW, JEDEC MO-153 variant 98ASH70702A), optimized for surface-mount PCB thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (AGND) | Analog Ground | Low-current reference ground for internal regulators and sensing; must be low-impedance connected to PGND. |
| 2 (FS) | Fault Status Output | Open-drain active-low flag requiring external 5 V pull-up; asserts during undervoltage, short-circuit, or overtemperature. |
| 3 (IN1), 19 (IN2) | Logic Input Controls | TTL/CMOS-compatible true-inputs; IN1 controls OUT1, IN2 controls OUT2; hysteresis improves noise immunity. |
| 4,5,16 (V+) | Positive Power Supply | Main power input pins (three connections); must be shorted on PCB with low-inductance traces to minimize voltage drop. |
| 6,7 (OUT1), 14,15 (OUT2) | H-Bridge Outputs | High-current totem-pole outputs driving motor terminals; include integrated body diodes for freewheeling. |
| 8,20 (DNC) | Do Not Connect | Manufacturing test pins; left floating or tied to GND - no functional role in application circuitry. |
| 9–12 (PGND) | Power Ground | High-current return path for motor current; connects directly to exposed thermal pad for optimal heat transfer. |
| 13 (D2), 18 (D1) | Disable Inputs | D2 (active-low) and D1 (active-high) independently force both outputs into tri-state (high-Z) mode. |
| 17 (CCP) | Charge Pump Capacitor | External capacitor connection (up to 33 nF) stabilizes internal charge pump for reliable 10 kHz PWM operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SMARTMOS H-Bridge | Monolithic construction eliminates external gate drivers and discrete MOSFETs; reduces BOM count and layout complexity. |
| Active Current Limiting with Foldback | Prevents destructive current surges by dynamically reducing ILIM from 6.5 A to 2.5 A as junction temperature rises from 160 °C to 175 °C. |
| Dual Independent Disable Inputs | D1 (active-high) and D2 (active-low) provide redundant, flexible system-level fault recovery without MCU reconfiguration. |
| Robust Fault Reporting | Single open-drain FS pin consolidates undervoltage, short-circuit, and overtemperature events into one diagnostic signal. |
| Exposed Thermal Pad (HSOP) | Enables direct PCB copper pour attachment; achieves ~5.0 °C/W junction-to-board thermal resistance with proper layout. |

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 |
|---|---|---|---|
| STSPIN840 | 4.5 A continuous, 3.0–45 V supply, SPI interface, integrated current sense; no FS pin or dual disable inputs. | Requires microcontroller SPI communication; lacks standalone fault reporting and hardware disable redundancy. | Preferred when digital diagnostics and closed-loop current control are required; not drop-in for MC33886VWR2 analog control schemes. |
| VNHD7008AY | 5.5 A continuous, 5.5–28 V supply, single enable pin, no charge pump; RDS(ON) = 150 mΩ typical. | Supports only one disable signal; limited to 28 V operation; no internal foldback current limiting. | Suitable for cost-sensitive 12 V systems where thermal margin is ample and fault reporting is handled externally. |
Compared with STSPIN840 and VNHD7008AY, MC33886VWR2 uniquely combines dual hardware disable inputs, analog fault reporting via FS, and junction-temperature-dependent current foldback - making it optimal for safety-critical, microcontroller-light, or harsh-environment DC motor control where robustness and simplicity are prioritized over digital configurability.

FAQ
What is the maximum continuous current rating of the MC33886VWR2?
The MC33886VWR2 is rated for 5.0 A continuous inductive load current under specified thermal conditions (TA ≤ 125 °C, proper PCB heatsinking). This rating assumes junction temperature remains ≤150 °C. At higher ambient temperatures or reduced copper area, derating applies per the thermal curves in the datasheet. The MC33886VWR2 achieves this with 120 mΩ RDS(ON) per FET at 25 °C and integrated thermal foldback protection.
Does the MC33886VWR2 require an external charge pump capacitor?
Yes, the MC33886VWR2 requires an external capacitor (up to 33 nF) connected between the CCP pin and PGND to stabilize its internal charge pump. While the device can operate without it, omitting the capacitor degrades PWM performance above 1 kHz and increases susceptibility to noise-induced switching errors. The MC33886VWR2 datasheet specifies this as mandatory for reliable 10 kHz operation and optimal gate drive strength.
How does the fault status (FS) pin function on the MC33886VWR2?
The FS pin on the MC33886VWR2 is an open-drain, active-low output that asserts logic low during undervoltage, output short-circuit, or overtemperature events. It requires an external pull-up resistor to 5.0 V. The MC33886VWR2 clears the FS flag automatically upon V+ recovery or manually via toggling either D1 or D2 - no MCU intervention is needed for basic reset. This behavior is documented in Table 6 (Truth Table) of the MC33886VWR2 datasheet.
Can the MC33886VWR2 drive a bipolar stepper motor?
Yes, the MC33886VWR2 can drive a bipolar stepper motor when two units are used - one for each phase - enabling full four-wire control with independent current limiting and fault reporting per winding. The MC33886VWR2 supports the required bidirectional current flow, dynamic braking (via IN1=IN2=H or L), and PWM microstepping up to 10 kHz. Its 5.0 A rating suits NEMA 17 and smaller stepper motors in industrial and robotics applications.
What is the purpose of the DNC pins (8 and 20) on the MC33886VWR2?
Pins 8 and 20 on the MC33886VWR2 are designated "Do Not Connect" (DNC) - they serve exclusively for factory test modes and have no functional role in application circuits. The MC33886VWR2 datasheet explicitly states these pins should be left floating or tied to ground; connecting them to active signals may disrupt internal test logic or cause undefined behavior. This differs from earlier MC33186DH1, where Pin 8 was COD (current detect output).
