Product details
Overview
MC10XS6225EK from NXP Semiconductors is a triple-channel automotive high-side switch IC with 25 mΩ (OUT1), 10 mΩ (OUT3), and unconnected (OUT2, OUT4) power channels, SPI 5.0 MHz daisy-chain control, programmable current sensing, and Fail-safe operation for LED/halogen lamp driving in ECU modules.
For engineers reviewing the MC10XS6225EK datasheet, MC10XS6225EK pinout, MC10XS6225EK application, or MC10XS6225EK equivalent, this page delivers verified channel configuration, RDS(on) values per output, thermal shutdown thresholds, SPI fault reporting capability, and direct-input Fail mode behavior - all confirmed for the exact MC10XS6225EK variant.
Technical Context
The MC10XS6225EK implements three protected high-side power channels: OUT1 (25 mΩ), OUT3 (10 mΩ), and OUT6 (logic-level external smart switch driver); OUT2 and OUT4 are NC. It uses a dual-supply architecture: VBAT (7–18 V) powers analog/charge pump circuits, while VCC (4.5–5.5 V) supplies SPI I/O and OUT6 logic.
Its functional safety design includes dynamic overcurrent threshold profiling, programmable open-load detection (ON/OFF state), thermal prewarning at 140 °C, and automatic transition to Fail mode upon SPI communication loss - retaining controllability via IN1/IN3 direct inputs and maintaining LIMP activation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Configuration | Triple high-side switch: OUT1 (25 mΩ), OUT3 (10 mΩ), OUT6 (logic driver); OUT2/OUT4 not connected |
| RDS(on) @ TJ = 150 °C | OUT1: ≤39.0 mΩ; OUT3: ≤16.0 mΩ - defines max conduction loss under worst-case thermal stress |
| SPI Interface | 16-bit, 5.0 MHz daisy-chainable - enables multi-device control with single MCU SPI port and minimal PCB routing |
| Operating Voltage Range | VBAT: 7.0–18 V full spec; extended 6.0–28 V - supports jump-start and load-dump transients without reset |
| Sleep Current | <5.0 µA @ VBAT = 12 V - meets automotive ECU low-power requirements during vehicle sleep states |
| Fault Reporting | Detects open load, short-to-battery, short-to-ground, overcurrent, overtemperature, clock fail - all reported via SPI register reads |
| Thermal Protection | Thermal shutdown at TJ ≥150 °C; prewarning at TJ ≥140 °C - enables system-level thermal derating before shutdown |
Pinout & Package
MC10XS6225EK uses a 32-pin SOICW-EP (exposed pad) package with lead-free (Pb-free) EK suffix. The exposed VBAT pad provides thermal and electrical connection to battery rail.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | High-side power output | 25 mΩ channel for main lighting load; supports up to 4.5 A continuous current with thermal management |
| OUT3 | High-side power output | 10 mΩ channel for secondary load; lower conduction loss ideal for high-current LED strings |
| OUT6 | Logic-level output | Drives external smart power switch (e.g., MC25XS6300); open-drain with internal pull-down |
| CSNS | Analog feedback | Reports scaled current (OUT1/OUT3), battery voltage, or die temperature - selectable via SPI |
| IN1, IN3 | Direct control inputs | Wake and Fail-mode control of OUT1 and OUT3 respectively; internal pull-down, 0–40 V tolerant |
| LIMP | Fault activation input | Asserting high forces Fail mode; retains output control while disabling PWM and SPI functions |
| CSB, SCLK, SI, SO | SPI interface | Standard 4-wire SPI with daisy-chain support; CSB active-low enables multi-device addressing |
| VBAT | Main power supply | Exposed pad connects directly to battery rail; supplies internal regulator, charge pump, and power stages |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC10XS6225BEK | Same RDS(on) specs and pinout; BEK version has wider RDS(on) max (41.0 mΩ vs. 39.0 mΩ) and higher IOLOFF threshold (1.1 A vs. 1.05 A) | Identical use cases; preferred where extended production lot traceability or alternate test screening is required | Select MC10XS6225BEK when sourcing from alternate NXP wafer lots with modified parametric screening - no layout or firmware changes needed |
| MC10XS6325EK | Adds functional OUT4 (10 mΩ); otherwise identical OUT1/OUT3 specs, package, and SPI interface | Required when fourth independent lighting channel is needed (e.g., fog lamp + DRL + low beam + high beam) | Choose MC10XS6325EK only if fourth protected output is necessary; shares same PCB footprint and driver software but increases channel count |
Compared with MC10XS6225BEK, the MC10XS6225EK offers tighter RDS(on) control and lower open-load OFF threshold - advantageous for precision current-sensitive LED arrays. Against MC10XS6325EK, it reduces cost and thermal load where only three channels are used, avoiding unused silicon area and associated leakage.

FAQ
What is the exact RDS(on) specification for each output channel of the MC10XS6225EK?
The MC10XS6225EK specifies RDS(on) ≤39.0 mΩ for OUT1 (25 mΩ channel) and ≤16.0 mΩ for OUT3 (10 mΩ channel) at TJ = 150 °C. OUT2 and OUT4 are not connected per datasheet Table 1. These values define maximum conduction loss under worst-case thermal conditions and are validated per JEDEC JESD47 reliability testing.
Does the MC10XS6225EK support daisy-chained SPI communication, and what is the maximum clock frequency?
Yes, the MC10XS6225EK supports daisy-chained SPI communication at up to 5.0 MHz, as confirmed in the "Features" section and Figure 1 of the MC12XS6D2 datasheet. This allows multiple MC10XS6225EK devices to share a single MCU SPI bus with minimal GPIO usage and deterministic latency for synchronized lighting control.
How does the Fail mode operate on the MC10XS6225EK, and which pins remain functional?
In Fail mode, the MC10XS6225EK disables SPI and PWM functions but retains control via IN1 (for OUT1) and IN3 (for OUT3), while LIMP input forces entry. OUT6 is disabled. This behavior ensures continued lighting functionality during MCU communication loss - a key requirement for automotive ASIL-B compliance per ISO 26262.
What is the purpose of the CSNS and SYNCB pins on the MC10XS6225EK, and how are they used together?
The CSNS pin outputs an analog voltage proportional to selected parameters (OUT1/OUT3 current, battery voltage, or die temperature), while SYNCB is an open-drain synchronization pulse that aligns MCU ADC sampling with internal PWM edges. Used together, they enable jitter-free current measurement in PWM-driven LED applications - a capability explicitly documented for the MC10XS6225EK in Section 3.2 and Table 3.
Is the MC10XS6225EK compatible with reverse battery conditions, and what is its rated protection level?
Yes, the MC10XS6225EK provides reverse polarity protection up to -16 V on the VBAT pin, as specified in Table 4 (Maximum Ratings) and Section 4.2 of the MC12XS6D2 datasheet. This protects against damage during incorrect battery terminal connection in automotive service scenarios without requiring external diodes or protection ICs.
