Product details
Overview
MC33886DHR2 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 MC33886DHR2 datasheet, MC33886DHR2 pinout, MC33886DHR2 application, or MC33886DHR2 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply support details specific to the MC33886DHR2 20-pin HSOP package with exposed thermal pad.
Technical Context
The MC33886DHR2 implements a fully protected H-bridge using SMARTMOS technology, integrating dual high-side/low-side MOSFETs with matched 120 mΩ RDS(ON) (typical, 25 °C), internal constant-off-time PWM current limiting, and junction-temperature-dependent foldback (ILIM drops to 2.5 A at 175 °C). Its dual disable inputs (D1 active-high, D2 active-low) force tri-state outputs independently of IN1/IN2 logic states.
It features an open-drain Fault Status (FS) output that reports undervoltage, short-circuit, and overtemperature events with latch-OFF behavior; recovery requires toggling D1 or D2. The CCP pin supports external charge pump capacitance (up to 33 nF) to sustain 10 kHz PWM operation across the full 5–40 V V+ range while maintaining stable gate drive under load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A - Sustained inductive load current capability with proper heatsinking (RθJB ≈ 5.0 °C/W). |
| RDS(ON) (per FET, 25 °C) | 120 mΩ - Low conduction loss enabling efficient motor drive at 5 A without external heat sinks in moderate-duty cycles. |
| PWM Frequency Support | Up to 10 kHz - Enables precise speed/torque control in brushed DC motors without audible noise or excessive switching loss. |
| Supply Voltage Range | 5.0 V to 40 V - Supports 12 V/24 V automotive and industrial rails; operation above 28 V requires derating per thermal limits. |
| Fault Reporting | Open-drain FS output - Active-low signal requiring 5 V pull-up; asserts on undervoltage, short-circuit, or >175 °C junction temperature. |
| Active Current Limit Threshold | 5.2–7.8 A (temp-dependent) - Internally regulated foldback protects against overload while allowing temporary peak current during motor startup. |
| Disable Inputs | D1 (active-high), D2 (active-low) - Independent tri-state control of both H-bridge outputs; enables safe system-level shutdown. |
Pinout & Package
MC33886DHR2 is housed in a 20-pin HSOP (Heat Sink Overmolded Package) with exposed copper thermal pad (package code VW, JEDEC MO-153 variant), optimized for surface-mount PCB thermal management via soldered pad and multiple PGND vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (AGND) | Analog Ground | Low-current reference ground; must be low-impedance connected to PGND near device to minimize noise coupling into control logic. |
| 2 (FS) | Fault Status Output | Open-drain active-low flag; requires external 5 V pull-up; signals undervoltage, short-circuit, or overtemperature latch-OFF. |
| 3 (IN1), 19 (IN2) | Logic Input Controls | TTL/CMOS-compatible true-inputs; IN1 controls OUT1, IN2 controls OUT2; hysteresis prevents noise-induced switching. |
| 4,5,16 (V+) | Positive Power Supply | Main power input pins; all three must be shorted on PCB with low-inductance traces to handle 5 A load current and reduce voltage spikes. |
| 6,7 (OUT1), 14,15 (OUT2) | H-Bridge Outputs | High-current totem-pole terminals; include integrated body diodes for freewheeling; connect directly to motor terminals. |
| 8,20 (DNC) | Do Not Connect | Manufacturing test pins; must remain unconnected or grounded-no functional role in application circuitry. |
| 9–12 (PGND) | Power Ground | High-current return path; connects to exposed thermal pad; requires wide copper pour and multiple vias to PCB ground plane. |
| 13 (D2), 18 (D1) | Disable Inputs | D2 = active-low, D1 = active-high; either forces both OUT1/OUT2 into high-impedance state independent of IN1/IN2 states. |
| 17 (CCP) | Charge Pump Capacitor | Connects to external 33 nF capacitor (to PGND); stabilizes internal gate drive voltage for reliable 10 kHz PWM operation. |
Key Features
| Feature | Design Value |
|---|---|
| SMARTMOS Integration | Monolithic construction combines control logic, charge pump, gate drivers, and 5 A MOSFETs in single die-eliminates discrete driver + FET complexity. |
| Junction-Temperature Foldback | Current limit threshold decreases linearly from 6.5 A (25 °C) to 2.5 A (175 °C), enabling graceful degradation instead of abrupt shutdown under overload. |
| Tri-State Disable Architecture | Dual independent disable inputs (D1/D2) allow fail-safe, microcontroller-coordinated shutdown without disturbing IN1/IN2 control logic states. |
| Robust Short-Circuit Protection | Detects hard shorts via high-side (11 A) and low-side (8.0 A) thresholds; triggers immediate latch-OFF with <4 µs response time. |
| Thermal Performance | Exposed pad + PGND pins enable ~5.0 °C/W junction-to-board thermal resistance-supports 5 A continuous operation with minimal external heatsinking. |

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 rating, integrated current sense, SPI interface, no FS pin; 36 V max V+; QFN-28 package. | Requires external MCU firmware for fault interpretation; better suited for closed-loop current-controlled designs than standalone fault reporting. | Select when digital control, current monitoring, or space-constrained layouts outweigh need for direct FS diagnostics and 5 A headroom. |
| VNHD7008AY | 5.3 A rating, 40 V max V+, embedded protection, but only one disable input; SO-20 package without exposed thermal pad. | Lacks dual-disable architecture and thermal performance of MC33886DHR2; higher RDS(ON) (180 mΩ) increases conduction loss at 5 A. | Choose for cost-sensitive industrial applications where 5 A margin and board-level thermal management are less critical. |
Compared with STSPIN840 and VNHD7008AY, the MC33886DHR2 uniquely combines 5.0 A continuous drive, dual independent disable inputs, open-drain fault status with latch-OFF behavior, and superior thermal dissipation via exposed HSOP pad-making it optimal for rugged, diagnostic-capable motor control where reliability and simplicity are prioritized over digital configurability.

FAQ
What is the maximum continuous current rating of the MC33886DHR2?
The MC33886DHR2 is rated for 5.0 A continuous inductive load current when operated within its specified ambient temperature range (-40 °C to 125 °C) and with adequate PCB heatsinking (RθJB ≈ 5.0 °C/W). This rating assumes proper layout of the exposed thermal pad and PGND connections to maintain junction temperature ≤150 °C under sustained load.
Does the MC33886DHR2 require an external charge pump capacitor?
Yes, the MC33886DHR2 requires an external capacitor (up to 33 nF) connected between the CCP pin and PGND. While the device can operate without it, the capacitor stabilizes the internal charge pump voltage, enabling reliable 10 kHz PWM operation across the full 5–40 V supply range and reducing gate drive noise during fast switching transitions.
How does the fault status (FS) pin behave during undervoltage conditions?
During undervoltage-when V+ drops below the 4.15–4.65 V hysteresis threshold-the MC33886DHR2 forces outputs to tri-state and pulls the open-drain FS pin low. Upon V+ recovery above the turn-on threshold (~4.5 V), the FS pin automatically returns high and outputs resume operation based on current IN1/IN2 states, provided no other fault persists.
Can the MC33886DHR2 drive a bipolar stepper motor?
Yes, a pair of MC33886DHR2 devices can be used to control a bipolar stepper motor in both directions. Each IC drives one phase (A or B) as a full H-bridge, supporting microstepping when combined with external current regulation and synchronized PWM timing from a host controller.
What is the purpose of the DNC pins (8 and 20) on the MC33886DHR2?
Pins 8 and 20 on the MC33886DHR2 are Do Not Connect (DNC) terminals used exclusively for manufacturing test purposes. They must remain unconnected or tied to ground in the final application-neither pin performs any functional role in normal operation or fault handling.
