Product details
Overview
MCZ33800EKR2 from NXP Semiconductors (formerly Freescale) is an automotive-grade engine control integrated circuit combining two programmable constant-current solenoid drivers (CCD1/CCD2), an octal low-side serial switch (OSS), and six external MOSFET gate pre-drivers (GD1–GD6). It operates from 5–36 V VPWR, delivers up to 800 mA CCD1 output current, supports SPI-controlled diagnostics, and integrates over-current, open-load, short-circuit, over-voltage, under-voltage, and thermal protection - deployed in fuel injector, EGR valve, and turbocharger actuator control within powertrain ECUs.
For engineers reviewing the MCZ33800EKR2 datasheet, MCZ33800EKR2 pinout, MCZ33800EKR2 application, or MCZ33800EKR2 equivalent, this page delivers verified functional identity, validated 54-pin SOICW-EP package mapping, confirmed SPI+parallel control architecture, real-time fault detection timing (e.g., 6–24 ms open-load detect), and cross-referenced alternatives for engine control subsystem design and BOM optimization.
Technical Context
The MCZ33800EKR2 implements a dual-domain analog/digital architecture: its CCD blocks use internal sense resistors (1.2 Ω CCD1, 5.0 Ω CCD2) with differential recirculation sensing (CCD1_REC/CCD2_REC) to regulate solenoid current via programmable DACs; its OSS outputs (OUT1–OUT8) employ self-limiting current protection (1–6 A) and dynamic fault filtering (50–650 µs timers). All outputs feature dedicated ground paths (PGND1–PGND3, CCD1_GND, CCD2_GND) and drain/source voltage monitoring (VDSNS1–VDSNS6, VSSNS123/VSSNS456).
Control is hybrid: SPI (4 MHz max, 3.3/5 V compatible) configures operating modes, dither parameters, and fault thresholds, while parallel inputs (P1/P3/P5/P7, PWM1–PWM6) enable direct hardware-level actuation. The internal oscillator (calibratable ±10% accuracy) synchronizes all timing-critical diagnostics including HEGO sensor resistance measurement via LRFDBK and VCAL-referenced analog circuits.

|---|---|
|
Use Scenario: Precise pulse-width modulation of diesel or gasoline fuel injectors in inline or V-type engines. IC Role / Device Role / Timing Role: MCZ33800EKR2 acts as the primary solenoid driver IC, delivering regulated current via CCD1 with dithering to control needle lift and injection timing. Use Value: Enables sub-millisecond current ramp control (2–4 V/µs slew rate) and real-time open-load detection (6–24 ms) to prevent misfire and protect injectors during cold starts. |

| Turbocharger Wastegate Control | Transmission Solenoid Management |
|
Use Scenario: Controlling pneumatic or electric wastegate actuators in variable geometry turbochargers (VGT) for boost pressure regulation. IC Role / Device Role / Timing Role: MCZ33800EKR2 employs GD1–GD6 pre-drivers to switch external high-side MOSFETs, enabling fast gate turn-on (<3 µs blanking) and short-circuit protection. Use Value: Gate drive sink/source current (2–5 mA) and programmable PWM (freq./duty) allow precise duty-cycle tuning for proportional boost control without external gate drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar engine control driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33810AEKR2 | Single CCD + octal OSS only; no gate pre-drivers; lower max VPWR (28 V); no HEGO diagnostics | Suitable for simpler injector-only modules without turbo or EGR actuation | Select when gate driving and multi-sensor diagnostics are unnecessary; reduces BOM count but sacrifices integration |
| MC33972TAER2 | Includes LIN transceiver and enhanced watchdog; adds wake-on-LIN; higher quiescent current (25 µA vs. 10 µA) | Targeted at body-control or gateway ECUs needing serial network interface | Choose only if LIN communication and system-level wake capability are required; not drop-in for pure powertrain actuation |
Compared with MCZ33800EKR2, MC33810AEKR2 offers reduced integration (no GDs, no HEGO), making it lighter-weight for cost-sensitive injector-only designs, while MC33972TAER2 trades driver density for network connectivity - neither matches the MCZ33800EKR2's combined CCD/OSS/GD architecture for comprehensive powertrain actuation.

FAQ
What is the maximum continuous current capability of the MCZ33800EKR2's octal serial switch outputs?
The MCZ33800EKR2's OSS outputs (OUT1–OUT8) support 350 mA continuous current per channel at TJ = 150°C. When paralleled (e.g., OUT1+OUT2 via P1 control), total current capacity doubles to 700 mA. This rating assumes proper PCB copper area, thermal pad soldering, and ambient temperature ≤ 125°C case temperature. Exceeding 350 mA per channel risks thermal shutdown activation.
Does the MCZ33800EKR2 support both SPI and parallel control simultaneously?
Yes, the MCZ33800EKR2 supports concurrent SPI and parallel control: SPI configures device settings (current levels, dither, fault thresholds), while parallel inputs (P1/P3/P5/P7, PWM1–PWM6) provide real-time hardware-level actuation override. For example, P1 can directly enable/disable OUT1/OUT2 even while SPI maintains background diagnostics - enabling fail-operational behavior during ECU software resets.
How does the MCZ33800EKR2 implement open-load detection on its constant-current drivers?
The MCZ33800EKR2 detects open-load faults on CCD1/CCD2 by monitoring the voltage difference between CCDx_OUT and CCDx_REC pins. When the driver is enabled and no load is present, this differential voltage exceeds 2.5 V (typ.), triggering a fault after a programmable timer (6–24 ms). The detection is active during both on-state and off-state, with separate timers and thresholds to distinguish open-circuit from short-circuit conditions.
What is the role of the REXT and RI_REF pins on the MCZ33800EKR2?
The REXT pin provides an external reference current path for the CCD1 regulator, while RI_REF sets the reference current for CCD2. A 39.2 kΩ resistor from RI_REF to GND programs CCD1 to 1075 mA and CCD2 to 232 mA. These pins enable precise, temperature-stable current calibration independent of VPWR fluctuations - critical for meeting OEM emission compliance requirements across full operating temperature range.
Can the MCZ33800EKR2 drive high-side MOSFETs directly?
No, the MCZ33800EKR2's GD1–GD6 outputs are designed as gate pre-drivers - they provide controlled voltage (5–9 V) and current (2–5 mA) but lack integrated high-side level-shifting or bootstrap circuitry. To drive high-side N-channel MOSFETs, an external bootstrap capacitor and diode are required. The GD outputs are commonly used with external high-side drivers (e.g., NCV8405) or P-channel MOSFETs in low-frequency applications.
