Product details
Overview
MCZ33880EW from NXP Semiconductors (formerly Freescale) is a configurable octal high-side/low-side power switch IC with 8-bit SPI control and dual PWM-direct inputs (IN5, IN6). It delivers RDS(ON) ≤ 0.55 Ω at 25°C, supports 0.8–2.0 A current-limited outputs, and operates across 5.5–24.5 V VPWR for automotive body electronics load driving.
For engineers reviewing the MCZ33880EW datasheet, MCZ33880EW pinout, MCZ33880EW application, or MCZ33880EW equivalent, this page provides verified technical context, real-world timing behavior, thermal grounding requirements for SOICW-32, fault reporting logic, and validated alternatives for automotive lighting and solenoid control designs.
Technical Context
The MCZ33880EW integrates SMARTMOS™ 5 technology-combining CMOS logic, bipolar/MOS analog circuitry, and independent double-diffused DMOS output transistors-to achieve <4.0 mA VDD supply current and <12 mA VPWR active current. Its architecture enables hardware-configurable high-side or low-side drive per channel, with individual +45 V (low-side) and –20 V (high-side) output clamping during inductive switching.
It implements cascaded fault reporting via SPI DO line, where each rising edge of SCLK shifts out one output's status bit (logic 1 = fault), synchronized with DI input shifting. The EN pin controls internal charge pump activation, and IN5/IN6 pins support OR-gated PWM control up to 2.0 kHz for outputs 5 and 6 without SPI interaction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VPWR) | 5.5 V to 24.5 V - supports full automotive battery range including cold-crank and load-dump conditions. |
| RDS(ON) (25°C) | 0.55 Ω typical - enables <1 W conduction loss per channel at 1.5 A, reducing thermal stress in SOICW-32 package. |
| Output Current Limit | 0.8 A to 2.0 A - programmable per channel via external resistor; protects incandescent lamps and solenoids from overcurrent. |
| Output Clamp Voltage | +45 V (low-side), –20 V (high-side) - suppresses inductive kickback without external TVS diodes in most automotive loads. |
| SPI Interface Speed | Up to 6.0 MHz - allows sub-10 μs command latency for real-time load sequencing and diagnostics. |
| Standby Current (IPWR) | 5.0 μA max at 13 V / 95°C - enables always-on functionality in body control modules without battery drain. |
| Thermal Ground Pins | Pins 8, 9, 24, 25 (TGND) - must be connected to PCB ground plane to achieve RθJL = 18°C/W and sustain 1.7 W power dissipation. |
Pinout & Package
MCZ33880EW uses a 32-pin SOICW (wide-body) package (Case 1324-02) with four dedicated thermal ground pins (TGND) for enhanced heat dissipation. Pin layout supports flexible high-side or low-side configuration per output pair (Dx/Sx), SPI interface (CS/SCLK/DI/DO), dual PWM direct control (IN5/IN6), and system enable (EN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Digital reference ground | Reference for logic signals; must be isolated from high-current return paths to avoid noise coupling into SPI interface. |
| VDD (Pin 2) | Logic supply input | 5.0 V ±5%; undervoltage lockout at 3.9 V disables outputs to prevent erratic behavior during brownout. |
| TGND (Pins 8, 9, 24, 25) | Internal die substrate connection | Direct thermal path to PCB ground plane; mandatory for thermal performance-RθJL = 18°C/W only when all four are soldered. |
| CS (Pin 18) | SPI chip select | Active-low; falling edge initiates fault status shift-out; rising edge latches new output states from shift register. |
| IN5 / IN6 (Pins 19, 14) | PWM direct control inputs | OR-gated with SPI bits for outputs 5 and 6; enables independent PWM dimming without SPI traffic overhead. |
| DO (Pin 32) | SPI fault status output | Tri-state until CS low; shifts out 8-bit fault word MSB-first on rising SCLK edges-bit = 1 indicates open/short/overtemp. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-configurable high-/low-side topology | Each of 8 outputs independently wired as high-side (Sx to load, Dx to battery) or low-side (Dx to load, Sx to GND) without reprogramming. |
| Independent overtemperature shutdown | TLIM = 155–185°C with 5–15°C hysteresis-prevents thermal runaway while allowing recovery after cooling. |
| Open-load detection (off-state) | IOCO = 0.3–1.0 mA threshold-identifies broken filaments or disconnected solenoids before enabling output. |
| Reverse battery protection | Integrated on VPWR pin-survives –16 V applied for indefinite duration without external components. |
| Cascadable fault reporting | Single DO line reports faults from multiple daisy-chained MCZ33880EW devices-reduces MCU GPIO count in multi-channel systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal high-/low-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33883 | Same pinout, but lacks IN5/IN6 PWM direct inputs and has higher RDS(ON) (0.7 Ω typ); no TGND pins-RθJA = 70°C/W vs. 18°C/W. | Not suitable for PWM-critical lighting or high-power solenoid drivers requiring thermal headroom. | Select MC33883 only if PWM control is handled entirely by MCU and board space allows larger heatsinking. |
| TPS27082L | 8-channel, 3.3 V–6.5 V logic-only supply; no VPWR operation; lower current limit (1.5 A max); no output clamping or thermal ground pins. | Limited to low-voltage industrial PLC I/O modules-not rated for 12/24 V automotive battery rails or inductive loads. | Choose TPS27082L only for 5 V embedded systems with non-inductive resistive loads and no fault-diagnostic requirements. |
Compared with MC33883 and TPS27082L, the MCZ33880EW uniquely combines automotive-grade VPWR operation (5.5–24.5 V), integrated output clamping, thermal ground optimization, and dual PWM-direct capability-making it the only option qualified for under-hood solenoid control and BCM lighting with full diagnostic coverage.

FAQ
What is the maximum operating voltage for MCZ33880EW on the VPWR pin?
The MCZ33880EW supports VPWR from 5.5 V to 24.5 V for full operation, with absolute maximum rating of –16 V to +50 V. This range accommodates automotive cold-crank (as low as 6 V) and load-dump (up to 40 V transient) conditions, though sustained operation above 24.5 V requires external clamping per design guidelines in the datasheet.
How does the MCZ33880EW implement open-load detection?
The MCZ33880EW detects open loads in off-state by sourcing 0.3–1.0 mA through each output and measuring voltage at Dx/Sx terminals. If voltage exceeds 1.0–3.0 V (VOUTth(F)), the device flags an open-circuit fault via the DO pin. This occurs independently per channel and requires no external components.
Can MCZ33880EW outputs be paralleled to increase current capacity?
Yes-MCZ33880EW outputs can be paralleled due to the positive temperature coefficient of its DMOS RDS(ON). Paralleling all eight outputs reduces effective RDS(ON) and increases current limit proportionally (e.g., ~16 A total with 2.0 A per channel), but thermal management must account for cumulative power dissipation in the SOICW-32 package.
What is the function of the TGND pins on MCZ33880EW?
The TGND pins (8, 9, 24, 25) connect internally to the silicon die substrate and serve as primary thermal conduction paths. They must be soldered to a large PCB ground plane to achieve RθJL = 18°C/W. Without this connection, junction temperature rise exceeds safe limits under sustained 1.7 W dissipation.
Does MCZ33880EW support daisy-chained SPI fault reporting?
Yes-the MCZ33880EW supports true daisy chaining: DO of one device connects to DI of the next, with shared SCLK and CS lines. On each CS falling edge, fault status from all devices shifts out sequentially, enabling centralized diagnostics across dozens of loads using a single MCU SPI port.
