Product details
Overview
MC33899VW from NXP (formerly Freescale) is a programmable H-bridge power IC designed for bidirectional DC motor control in automotive powertrain systems. It delivers up to 3.0 A continuous load current, supports PWM operation up to 11 kHz, features SPI-configurable slew rate and current limits, and provides analog current feedback via CSNS pin - enabling precise torque/speed regulation in throttle or EGR actuators.
For engineers reviewing the MC33899VW datasheet, MC33899VW pinout, MC33899VW application, or MC33899VW equivalent, key selection criteria include its 30-pin HSOP package with exposed thermal pad, -40°C to +125°C operating range, VIGNP input tolerance up to 40 V (load dump), integrated charge pump for high-side drive, and diagnostic reporting of open/short-circuit, overtemperature, and undervoltage faults via SPI.
Technical Context
The MC33899VW implements a full H-bridge using four N-channel MOSFETs with synchronous rectification control and dead-time management (1.0–3.0 μs). Its internal charge pump enables gate drive above VIGNP, ensuring low RDS(ON) (<165 mΩ at 125°C) across the 6.0–26.5 V VIGNP range.
SPI interface (up to 6.25 MHz) configures diagnostic thresholds, slew modes (1X/2X/4X), and current limits (5.3–15.0 A low-side, 5.8–17.9 A high-side); fault status includes latched short-circuit detection (4–11 μs filter), thermal shutdown at 157.5–172.5°C, and voltage monitoring with UV/OV lockout on VIGNP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIGNP Range | 6.0 V to 26.5 V operating; survives 40 V load dump transients - suitable for 12 V automotive battery systems with transient immunity. |
| Continuous Output Current | 3.0 A @ 11 kHz PWM - supports medium-power DC motors in engine control actuators. |
| RDS(ON) (per FET) | <165 mΩ @ TA = 125°C, VIGNP = 6.0 V - minimizes conduction loss and thermal stress under high-temp operation. |
| Slew Time Control | Adjustable 1.0–12.8 μs via RS resistor + SPI mode - balances EMI suppression and switching efficiency. |
| SPI Interface Speed | Up to 6.25 MHz - enables fast configuration and real-time fault register reads without MCU bus contention. |
| Thermal Shutdown Threshold | 157.5–172.5°C with 3–10°C hysteresis - prevents latch-up during sustained overload while allowing recovery after cooling. |
| Current Sense Accuracy | kCSNS = 250–500 × 10−3 (1/400 typical) - provides proportional analog feedback for closed-loop current control. |
| Fault Reporting | Open load, short-to-battery, short-to-ground, die temperature, VIGNP UV/OV - all latched and readable via SPI status register. |
Pinout & Package
MC33899VW uses a 30-pin HSOP (Heat Sink Overmolded Package) with exposed thermal pad (Tab), rated for RθJC < 0.5°C/W. The package is Pb-free (VW suffix) and qualified for automotive underhood environments (-40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIGNP (Pins 8,9,22,23) | Protected ignition supply input | Main H-bridge power rail; accepts 6–26.5 V, withstands 40 V transients; not reverse-voltage protected. |
| S0 (Pins 10,11), S1 (Pins 20,21) | H-bridge motor outputs | Paired pins per output; connect together on PCB to drive bidirectional motor windings. |
| GND (Pins 12,19), Tab | Power/thermal ground | High-current return path; exposed pad must be soldered to PCB ground plane for thermal and electrical integrity. |
| FWD / REV (Pins 26,27) | Direction control inputs | TTL-compatible logic inputs defining forward/reverse motor rotation per truth table; include 50 μA pull-downs. |
| PWM (Pin 25) | Speed/torque modulation input | Direct PWM signal up to 11 kHz controls duty cycle; includes 50 μA pull-down for fail-safe disable. |
| EN1 / EN2 (Pins 15,16) | Master enable inputs | Logic OR function: either low disables all outputs; both high enables run mode per Table 6. |
| CSNS (Pin 30) | Current sense output | Analog current mirror output (IOUT/400 typical); clamped to VCC; requires external RCSNS for I-to-V conversion. |
| DO / DI / SCLK / CS (Pins 2,3,4,5) | SPI interface | Full-duplex slave interface; DO tri-stated when CS high; immune to <50 ns glitches on CS. |
| REDIS (Pin 7) | Auto-re-enable control | Capacitor-timed re-enable of low-side MOSFET after current comparator trip; disabled when shorted to GND. |
| RS (Pin 24) | Slew rate programming | Resistor-set base slew time (1–12.8 μs); SPI selects 1X/2X/4X multiplier for dynamic adjustment. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable current limiting | SPI-selectable high-side (5.8–17.9 A) and low-side (5.3–15.0 A) limits prevent destructive overcurrent during shorts. |
| Integrated charge pump | Generates gate drive voltage > VIGNP to fully enhance high-side N-MOSFETs without external boost circuitry. |
| Synchronous rectification | Active control of high-side MOSFETs during freewheeling reduces conduction losses vs. body-diode operation. |
| LSCMP one-shot output | Dedicated 5–10 μs pulse on LSCMP pin per low-side current comparator event - enables hardware-triggered fault response. |
| Thermal shutdown with latch | Junction temperature >172.5°C latches all outputs off until SPI clear-fault command - prevents thermal runaway. |
| Pb-free HSOP package | 30-pin thermally enhanced package with exposed pad (VW suffix) meets RoHS and automotive reliability standards. |

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 |
|---|---|---|---|
| MC33883VW | Single H-bridge, lower current rating (2.5 A), no SPI current limit programming - fixed thresholds only. | Lacks diagnostic flexibility and programmable slew; suited for cost-sensitive non-safety-critical loads. | Select MC33883VW only if SPI configurability and 3.0 A capability are unnecessary and BOM cost is primary constraint. |
| DRV887x-Q1 series (e.g., DRV8872-Q1) | Higher integration (integrated current sense amp, adjustable decay modes), but no charge pump - limited to lower VIN range (4.5–37 V). | Supports faster PWM (≥20 kHz) and advanced current regulation; lacks VIGNP load-dump immunity beyond 37 V. | Choose DRV8872-Q1 for higher-frequency motor control where 40 V transient immunity is not required and integrated sensing is preferred. |
Compared with MC33899VW, MC33883VW offers reduced feature set and lower current handling, while DRV8872-Q1 trades VIGNP transient robustness for higher PWM frequency and integrated sensing - making MC33899VW optimal for 12 V automotive powertrain applications demanding load-dump immunity, SPI diagnostics, and thermal resilience.

FAQ
What is the maximum PWM frequency supported by the MC33899VW?
The MC33899VW supports PWM operation up to 11 kHz, as specified in the Dynamic Electrical Characteristics table. This frequency enables responsive speed and torque control for automotive actuators while maintaining manageable switching losses and EMI. Operation beyond 11 kHz is not guaranteed and may compromise thermal performance or fault detection timing.
Does the MC33899VW require an external charge pump capacitor?
Yes, the MC33899VW requires an external 0.1 μF capacitor connected to the CRES pin (Pin 6) to serve as the reservoir for the internal charge pump. This capacitor ensures stable gate drive voltage for the high-side MOSFETs across the full VIGNP range (6–26.5 V), directly enabling low RDS(ON) performance without external boost circuitry.
How does the REDIS pin function in the MC33899VW?
The REDIS pin (Pin 7) controls automatic re-enable of the low-side MOSFET after a current comparator trip. A capacitor (e.g., 2.2 nF) sets a ~75 μs delay before re-enabling; grounding REDIS disables the feature. This allows controlled retry behavior during transient overloads without requiring MCU intervention - a key reliability feature in automotive motor control.
Can the MC33899VW operate with a 3.3 V logic supply?
Yes, the MC33899VW supports 3.3 V logic interfacing via the VCCL pin (Pin 28), which powers internal digital circuitry, and VDDQ (Pin 1), which sets logic-high levels for DO and LSCMP outputs. With VDDQ = 3.3 V, DO and LSCMP outputs comply with 3.3 V logic thresholds, enabling direct connection to 3.3 V microcontrollers without level shifting.
What fault conditions does the MC33899VW report via SPI?
The MC33899VW reports five fault categories via its SPI-accessible status register: open circuit (load disconnect), short-circuit to VIGNP (battery), short-circuit to ground, die temperature out-of-range (over-temperature warning or shutdown), and VIGNP undervoltage. All faults are filtered and latched, and cleared only via SPI command - ensuring deterministic diagnostic visibility for safety-critical systems.
