Product details
Overview
MC10XS4200CFK from NXP Semiconductors is a dual 24 V, 10 mΩ high-side switch IC designed for truck, bus, and industrial load control. It features two independently controllable channels, 8.5 A steady-state current per channel, 3.3 V/5.0 V SPI interface up to 8.0 MHz, and integrated overcurrent, short-circuit, and overtemperature protection with programmable autoretry. It drives bulbs, solenoids, and DC motors in 24 V vehicle power distribution systems.
For engineers reviewing the MC10XS4200CFK datasheet, MC10XS4200CFK pinout, MC10XS4200CFK application, or MC10XS4200CFK equivalent, key selection criteria include its 10 mΩ RDS(ON) at 25 °C, dual-channel autonomous operation via internal PWM clock, dynamic overcurrent threshold profile, openload detection in both ON/OFF states (7.0 mA typ. for LED), and Fail-safe mode activation upon SPI communication loss.
Technical Context
The MC10XS4200CFK implements SMARTMOS technology with dual independent gate drivers, each featuring individually programmable slew rates and selectable overcurrent profiles (bulb vs. DC motor) via CONF0/CONF1 pins or SPI. Its internal oscillator enables fully autonomous operation without external clock dependency.
It integrates analog current sensing (CSNS) with two programmable ratios (1/3000 or 1/1000), temperature monitoring, and openload detection with 4.0–5.5 V threshold in OFF state and 7.0 mA threshold in ON state. Fault status is reported via FSB (active-low) and Fail-safe output FSOB, while SYNC enables microcontroller synchronization during autonomous operation.

Pinout & Package
MC10XS4200CFK uses a 23-pin PQFN package (12 × 12 mm, Pb-free FK suffix) with exposed thermal pad (pin 15). The package supports high-power dissipation via VPWR flag surface (RθJC = 0.22 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HS0 / HS1 | Power switch outputs | High-side drain terminals connected directly to loads; rated for -28 V to +58 V, 8.5 A continuous |
| VPWR (pins 15,18,21) | Main power supply | Primary power input for MOSFETs and analog circuitry; internally tied; pin 15 is thermal pad |
| VDD (pin 13) | Digital supply | 3.3 V or 5.0 V supply for SPI logic; separate from VPWR to isolate digital noise |
| CSB / SCLK / SI / SO | SPI interface | Standard 4-wire SPI with chip select, clock, data in/out; supports daisy-chaining and 8 MHz operation |
| IN0 / IN1 | Direct control inputs | Hardware override pins with internal pull-down; enable immediate channel switching without SPI |
| CSNS | Current/temperature sense output | Current-proportional output (CSR0/CSR1 selectable) or temperature-proportional voltage; requires external pull-down |
| FSOB / FSB | Fault signaling outputs | FSOB: active-low Fail-safe indicator; FSB: active-low general fault flag; both open-drain, require pull-ups |
| SYNC | Synchronization output | Logic-low pulse when CSNS signal is within accuracy window; enables precise timing of current sampling |
| CONF0 / CONF1 | Overcurrent profile select | Hardware-selectable bulb or DC motor latched overcurrent handling; pull-down required |
| RSTB / CLOCK | Reset and clock inputs | RSTB initializes registers and enters Sleep mode; CLOCK provides external timebase for PWM operation |

FAQ
What is the maximum continuous current rating per channel for the MC10XS4200CFK?
The MC10XS4200CFK supports up to 8.5 A steady-state current per channel, validated under conditions where the junction temperature remains within its 150 °C limit. This rating assumes proper PCB thermal design with adequate copper area and thermal vias connected to the VPWR flag surface (pin 15), as specified in the datasheet's thermal resistance (RθJC = 0.22 °C/W) and energy dissipation limits (128 mJ single-pulse).
Does the MC10XS4200CFK support openload detection for LED loads?
Yes, the MC10XS4200CFK supports openload detection in the ON state with a typical threshold of 7.0 mA, making it suitable for LED string monitoring. This function operates when CSNS_ratio = 1 and fast slew rate is selected, and does not require external sense resistors-enabling direct integration into LED lighting modules without added components.
How does the Fail-safe mode operate in the MC10XS4200CFK?
When SPI communication is lost, the MC10XS4200CFK automatically enters Fail-safe mode: FSOB asserts low, but both channels remain operational and controllable via IN0/IN1 direct inputs. All protective functions-including overcurrent, short-circuit, and overtemperature detection-remain active, ensuring continued safe operation without MCU supervision.
What are the voltage ratings for VPWR and reverse battery tolerance of the MC10XS4200CFK?
The MC10XS4200CFK has a full-spec VPWR range of 8.0–36 V and an extended operating range of 6.0–58 V. Its reverse battery tolerance is -28 V, as confirmed in Table 1 of the datasheet for the "MC10XS4200CFK(2)" variant. This rating applies continuously-not just transiently-and is distinct from versions like BFK/DFK which support -32 V.
Can the MC10XS4200CFK be used in autonomous (standalone) operation without a microcontroller?
Yes, the MC10XS4200CFK supports fully autonomous operation using its internal calibrated oscillator. When configured via SPI to use internal clock mode, it can generate PWM signals, manage overcurrent responses, and perform diagnostics without any ongoing MCU interaction-ideal for safety-critical subsystems requiring fail-operational behavior.
