Product details
Overview
MC33XS2410EL from NXP Semiconductors is a quad-channel automotive-grade high-side switch with four 100 mΩ and two configurable 50 mΩ (parallel mode) NMOS outputs, operating from 3.0 V to 60 V supply, featuring integrated 12-bit ADC, SPI-controlled diagnostics, and AEC-Q100 Grade 1 qualification for engine control units and solenoid drivers.
For engineers reviewing the MC33XS2410EL datasheet, MC33XS2410EL pinout, MC33XS2410EL application, or MC33XS2410EL equivalent, key selection considerations include its dual parallel-mode current capability (3.6 A), open-load detection (10 mA), programmable active current limit, ISO 7637-2/16750-2 transient immunity, and HTSSOP28 thermal-enhanced package with exposed pad grounding.
Technical Context
The MC33XS2410EL integrates four independent high-side power switches with digital PI PWM closed-loop current regulation, each controllable via SPI or direct logic inputs (IN1–IN4). Its architecture includes a 16-bit SPI interface with daisy-chain support, watchdog timer with configurable timeout (2 ms–256 ms), and fault reporting via open-drain FAULT pin or SPI status bits (ST1-ST0).
It implements parallel mode (OUT1/OUT2 and OUT3/OUT4) to halve RDS(on) and double current capacity, while maintaining per-channel temperature, voltage, and current sensing via a shared 12-bit ADC with ±6% accuracy above 1 A and ±6.5% above 5.0 V. Safe mode activation occurs on LHM pin assertion, watchdog timeout, or overload detection-bypassing SPI control while preserving diagnostic read access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 60 V VPWR - supports 12 V/24 V automotive and industrial systems up to 60 V bus operation |
| RDS(on) (per channel) | 100 mΩ at 25 °C - enables 1.8 A nominal load current per output in standard mode |
| RDS(on) (parallel mode) | 50 mΩ at 25 °C - doubles current capability to 3.6 A for paired outputs (OUT1/2 or OUT3/4) |
| Active Current Limit | 5 A - programmable threshold minimizes short-circuit energy dissipation and thermal stress |
| SPI Interface | 16-bit, 3.3 V/5.0 V compatible, daisy-chain capable - enables multi-device configuration without additional GPIOs |
| ADC Resolution & Accuracy | 12-bit with ±6% current error (>1 A) and ±6.5% voltage error (>5.0 V) - enables precise real-time load monitoring without external sensors |
| Operating Temperature | –40 °C to +150 °C junction - qualified per AEC-Q100 Grade 1 for under-hood automotive environments |
Pinout & Package
MC33XS2410EL uses the HTSSOP28 (SOT1172-4) package: plastic thermal-enhanced thin shrink small outline with 28 leads, 0.65 mm pitch, 4.4 mm body width, and exposed die pad requiring soldering to PCB ground for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VPWR (pins 1,2,13,14,15,16,27,28) | Power supply input | High-current path for NMOS drain connection; multiple pins reduce IR drop and improve thermal dissipation |
| OUT1–OUT4 (pins 3,26,12,17) | High-side switch outputs | NMOS source terminals driving loads; support independent or parallel (OUT1/2, OUT3/4) configurations |
| IN1–IN4 (pins 25,24,23,22) | Direct logic inputs | Pulldown-enabled TTL/CMOS-compatible control; OR-logic used in parallel mode (e.g., IN2 → OUT1 when OUT1/2 parallel) |
| SCLK, SS, MOSI, MISO (pins 8,6,7,9) | SPI interface | Full-duplex synchronous communication; SS active-low enables daisy-chain synchronization across multiple devices |
| FAULT (pin 4) | Interrupt output | Open-drain warning/IRQ signal; asserts LOW on critical faults (e.g., overtemperature, watchdog timeout) |
| LHM (pin 18) | Safety mode enable | Hardware-initiated safe mode entry - bypasses SPI control and routes INx directly to corresponding OUTx |
| VDD (pin 19), VSPI (pin 10) | Logic supplies | VDD powers internal logic (auto-switches to VPWR if <3.95 V); VSPI independently supplies SPI I/O for 3.3 V/5.0 V level compatibility |
Key Features
| Feature | Design Value |
|---|---|
| Digital PI PWM current regulation | Enables closed-loop current control per channel without external op-amps or DACs - reduces component count and improves stability under varying load conditions |
| Configurable parallel mode | Allows OUT1/OUT2 or OUT3/OUT4 to be hardware-wired and software-configured as single 50 mΩ switches - doubles current drive while retaining independent diagnostics |
| 10 mA open-load detection in ON state | Identifies disconnected loads during active switching - prevents false fault triggering and supports LED/solenoid health monitoring |
| Programmable interrupt generator | Routes warnings (WARN) or interrupts (IRQ) to FAULT pin or SPI status bits - enables prioritized fault handling with IRQ overriding WARN |
| Reversed polarity & battery transient protection | Withstands –35 V reverse battery and clamps transients per ISO 7637-2 Pulse 1/2/5a - eliminates need for external TVS or polarity protection diodes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel 160 mΩ switch; no integrated ADC or parallel mode; 40 V max VPWR | Limited to lower-current single-load applications; lacks per-channel telemetry and multi-output coordination | Choose when only one robust channel is needed and system-level ADC is already present |
| VNQ7E100AJTR | Quad-channel 100 mΩ switch; no SPI interface; analog current sense output only; 28 V max VPWR | Relies on external MCU ADC for diagnostics; no daisy-chain or programmable PWM modules | Prefer where SPI complexity is undesirable and simple analog monitoring suffices |
Compared with TPS4H160-Q1 and VNQ7E100AJTR, the MC33XS2410EL delivers higher integration (integrated 12-bit ADC, SPI-configurable PWM, parallel mode), broader voltage range (60 V), and automotive safety features (AEC-Q100 Grade 1, ISO 7637-2 compliance), making it optimal for centralized, diagnostics-rich power distribution in modern ECUs.

FAQ
What is the maximum continuous supply voltage rating for the MC33XS2410EL?
The MC33XS2410EL is rated for continuous operation up to 60 V on the VPWR supply pins. It is engineered for 12 V and 24 V automotive bus/truck mission profiles, with maximum continuous voltage dependent on application-specific thermal design and transient conditions per ISO 16750-2. The device includes active voltage clamp circuitry to protect against battery transients.
Does the MC33XS2410EL support daisy-chaining multiple devices via SPI?
Yes, the MC33XS2410EL supports daisy-chain configuration through its 16-bit SPI interface. Devices are connected by routing the MISO of one unit to the MOSI of the next, with all SS pins tied to a common controller select line. Each device requires one 16-bit SPI frame for programming, enabling scalable multi-channel control without additional GPIO resources.
How does the MC33XS2410EL handle communication loss with the host MCU?
When SPI communication is lost, the MC33XS2410EL enters safe mode if the watchdog timeout flag is enabled (WDT_REG[6] = 1). In safe mode, outputs are controlled directly by IN1–IN4 logic inputs while SPI remains available for diagnostic reads. This ensures continued operation and protection without requiring host intervention.
What is the purpose of the exposed center pad on the MC33XS2410EL HTSSOP28 package?
The exposed center pad on the MC33XS2410EL's HTSSOP28 package must be soldered to PCB ground to achieve enhanced thermal dissipation and low-impedance electrical return. This improves junction-to-board thermal resistance and stabilizes ground reference for sensitive analog functions like the 12-bit ADC and current sensing circuits.
Can the MC33XS2410EL drive incandescent bulbs and what is the maximum supported wattage?
Yes, the MC33XS2410EL is specified to drive incandescent bulbs up to 21 W. This capability is enabled by its 100 mΩ RDS(on), 1.8 A nominal per-channel current rating, and robust inrush current handling - validated for filament lamp loads in automotive interior and exterior lighting applications.
