Product details
Overview
MC15XS3400DPNAR2 from NXP Semiconductors is a quad high-side switch IC designed for automotive lighting control, integrating four 15 mΩ (at 25 °C) protected MOSFETs capable of driving 55 W/28 W incandescent bulbs, Xenon modules, or LED loads. It operates from 6.0 V to 20 V (extended mode: 4.0 V–28 V), features 8.0 MHz 16-bit SPI interface with daisy-chain capability, and supports programmable slew-rate outputs for EMC optimization.
For engineers reviewing the MC15XS3400DPNAR2 datasheet, MC15XS3400DPNAR2 pinout, MC15XS3400DPNAR2 application, or MC15XS3400DPNAR2 equivalent, key selection considerations include its quad-channel high-side architecture, fault-current programmability, Fail-safe mode for MCU failure recovery, analog current feedback with selectable ratio, and 24-pin PQFN package with thermal resistance RθJA = 30 °C/W.
Technical Context
The MC15XS3400DPNAR2 implements a digitally controlled high-side power distribution architecture with independent per-channel diagnostics and protection. Its internal block includes a calibratable oscillator for PWM generation, programmable overcurrent trip levels (configurable via SPI across seven time steps), and smart shutdown with time-limited autoretry on overtemperature, severe short-circuit, or overvoltage events.
Each HS[0:3] output supports dual control paths-parallel direct input (IN0–IN3) or SPI command-and features selectable slew rate (slow/medium/fast), open-load detection in both ON/OFF states, short-to-battery detection, and analog current sensing via CSNS with two programmable current-sense ratios (1/8700 or 1/4350).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) (25 °C) | 15 mΩ per channel at VPWR = 10 V - enables low conduction loss for 5 A continuous load per channel |

| SPI Interface | 8.0 MHz, 16-bit, 3.3 V/5.0 V compatible with daisy-chain - allows centralized control of multiple devices with minimal MCU GPIO usage |
| Fault Detection Blanking Time | 5.0 μs (C variant) - suppresses false fault triggers during transient switching events |
| Thermal Shutdown Threshold | 155 °C (min), 195 °C (max) - protects against sustained overload while allowing temporary peak currents |

Pinout & Package
MC15XS3400DPNAR2 is housed in a 24-pin PQFN package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad. Pin 14, 17, and 23 are internally shorted GND terminals; pins 4 and 20 are NC (no connect). The package meets JEDEC J-STD-020C Pb-free reflow standards with MSL3 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HS0–HS3 (pins 18, 19, 21, 22) | High-side power outputs | Protected 15 mΩ switches delivering VPWR to loads; support PWM dimming and diagnostic feedback |
| CSNS (pin 1) | Analog current/temperature sense | Provides ground-referenced voltage proportional to selected HS output current or die temperature (SPI-selectable ratio) |
| IN0–IN3 (pins 2, 3, 5, 6) | Direct control inputs | Enable hardware-level ON/OFF control of corresponding HS outputs without SPI involvement |
| FS (pin 7) | Fault status output | Open-drain active-low signal indicating overcurrent, overtemperature, or short-circuit faults |
| FSI (pin 24) | Fail-safe input | Enables watchdog timeout; if unasserted, forces HS outputs into preconfigured safe state upon MCU failure |
| SCLK/CS/SI/SO (pins 11, 10, 12, 16) | SPI interface | Full-duplex 16-bit serial communication with daisy-chain support for multi-device configurations |
| VDD (pin 13), VPWR (pin 15), GND (pins 14,17,23) | Power supplies | VDD powers digital logic (3.0–5.5 V); VPWR supplies high-side drivers (4.0–28 V); GND pins share common reference |
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 |
|---|---|---|---|
| Infineon BTS716G | Single-channel 16 mΩ high-side switch; no integrated current sense or SPI interface; analog status flag only | Requires four separate ICs for quad functionality; lacks programmable slew rate and Fail-safe mode | Choose for cost-sensitive, non-networked lighting nodes where SPI control and diagnostics are unnecessary |
| STMicroelectronics VNQ7E100AJ | Quad-channel with 10 mΩ RDS(on); SPI-compatible but no daisy-chain; fixed slew rate; no Fail-safe input | Higher drive capability but less flexible fault configuration; no watchdog timeout or FSI-driven safe state | Prefer when lower on-resistance is critical and system-level fail-safe logic resides in MCU firmware |
Compared with BTS716G and VNQ7E100AJ, the MC15XS3400DPNAR2 uniquely integrates daisy-chain SPI, Fail-safe input, and dual-mode (direct/SPI) control - enabling scalable, safety-aware lighting architectures with reduced interconnect complexity and deterministic fault response.

FAQ
What is the maximum continuous output current per channel of the MC15XS3400DPNAR2?
The MC15XS3400DPNAR2 supports up to 6 A continuous output current per channel (HS0–HS3), limited by junction temperature. At 25 °C ambient and with proper PCB thermal design (e.g., 4-layer board), it sustains 5 A with RDS(on) = 15 mΩ, resulting in ≤375 mW conduction loss per channel. Derating is required above 85 °C ambient per the thermal resistance profile (RθJA = 30 °C/W).
Does the MC15XS3400DPNAR2 support daisy-chained SPI communication?
Yes, the MC15XS3400DPNAR2 supports daisy-chained SPI communication via its SI and SO pins. When configured in daisy-chain mode, the SO pin of one device connects to the SI pin of the next, allowing a single MCU SPI port to control and monitor multiple MC15XS3400DPNAR2 units with minimal GPIO overhead and synchronized register access.
How does the Fail-safe mode operate in the MC15XS3400DPNAR2?
The MC15XS3400DPNAR2 enters Fail-safe mode when the FSI pin is pulled low or left floating (internal pull-up disabled), triggering a watchdog timeout (~310 ms typical). Upon timeout, HS outputs assume preprogrammed safe states (ON/OFF) independent of MCU commands - ensuring predictable behavior during MCU lockup, reset, or communication failure, a key requirement for ISO 26262 ASIL-B systems.
Can the MC15XS3400DPNAR2 drive LED loads directly?
Yes, the MC15XS3400DPNAR2 is qualified for LED load driving, including ON-state open-load detection down to 2.5 mA (for LEDs with VHS = VPWR − 0.75 V) and programmable overcurrent thresholds optimized for LED surge currents. Its 15 mΩ RDS(on) minimizes forward-voltage drop, and selectable slew rate reduces EMI in sensitive LED lighting environments.
What is the purpose of the CSNS pin on the MC15XS3400DPNAR2?
The CSNS pin on the MC15XS3400DPNAR2 provides an analog voltage output proportional to either the current through a selected HS output (via programmable current-sense ratio: 1/8700 or 1/4350) or the die temperature. This enables real-time current monitoring for closed-loop control or thermal derating, with ±5% accuracy achievable after single-point calibration at 5 A - eliminating need for external sense resistors or temperature sensors.
