Product details
Overview
MC07XSG517DEKR2 from NXP Semiconductors is a penta-channel high-side switch IC designed for precision control, protection, and diagnosis of low-voltage resistive and inductive loads. It features five protected high-side outputs (OUT1–OUT5) with RDS(on) values of 17 mΩ (OUT1/OUT2) and 7.0 mΩ (OUT3/OUT4/OUT5), 16-bit 5.0 MHz SPI interface, and operating supply range of 7.0 V to 30 V VPWR with sleep current < 5.0 μA. It is used in automotive exterior lighting and industrial automation systems requiring robust fault reporting and fail-safe operation.
For engineers reviewing the MC07XSG517DEKR2 datasheet, MC07XSG517DEKR2 pinout, MC07XSG517DEKR2 application, or MC07XSG517DEKR2 equivalent, key selection considerations include channel-specific RDS(on), programmable current sense ratio, daisy-chainable SPI diagnostics, reverse polarity protection (–16 V), and compatibility with SOIC-54 exposed-pad footprint across the MC32XSG family.
Technical Context
The MC07XSG517DEKR2 integrates SMARTMOS technology to deliver self-protected high-side switching with active clamp circuitry for inductive load turn-off. Its architecture supports dual power domains: VPWR (7.0–30 V) powers analog blocks, gate drivers, and charge pump, while VCC (4.5–5.5 V) supplies SPI I/Os and OUT6 driver.
It operates in four modes-Sleep, Normal, Fail, and Power Off-with Normal mode enabling full SPI-configurable PWM control (8-bit duty cycle, prescaler per channel), and Fail mode enabling direct IN1–IN4 input control of OUT1–OUT4 while disabling OUT5/OUT6. Diagnostics include open-load, short-to-supply/ground, overcurrent, overtemperature, and undervoltage detection reported via SPI or SO register.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 5 independent high-side switches (OUT1–OUT5); OUT6 controls external smart power switch |
| RDS(on) (OUT1/OUT2) | 17 mΩ max - enables ≤5.5 A continuous current with thermal management on 4-layer board |
| RDS(on) (OUT3/OUT4/OUT5) | 7.0 mΩ max - supports ≤11 A continuous current per channel under same thermal conditions |
| SPI Interface | 16-bit, 5.0 MHz full-duplex with daisy-chain capability - allows multi-device control without additional MCU GPIOs |
| Supply Range (VPWR) | 7.0 V to 30 V functional; –16 V reverse polarity tolerance - eliminates need for external reverse-battery protection diode |
| Sleep Current | < 5.0 μA at VPWR = 24 V - meets automotive module quiescent current requirements for always-on nodes |
| Operating Temp | –40 °C to +125 °C ambient - qualified for under-hood and industrial control cabinet deployment |
Pinout & Package
MC07XSG517DEKR2 uses a 54-pin SOIC package with exposed thermal pad (SOIC-54-EP), optimized for high-power dissipation and EMC performance in automotive and industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VPWR (Pin 55) | Main power supply input | Connects to battery rail (7–30 V); powers internal regulator, analog circuits, and gate drivers; rated for –16 V reverse polarity |
| VCC (Pin 8) | Logic supply input | Supplies SPI I/Os, OUT6 driver, and digital logic; must be 4.5–5.5 V; disconnect disables SPI communication |
| CSB (Pin 5) | SPI chip select | Active-low enable for SPI transactions; internal pull-up to VCC; high state places SO in high-impedance |
| SCLK (Pin 6) | SPI clock input | Accepts up to 5.0 MHz clock; internal pull-down; timing-critical for setup/hold compliance |
| SI (Pin 7) | SPI serial data input | Samples on rising SCLK edge; internal pull-down; carries 16-bit address/data words |
| SO (Pin 9) | SPI serial data output | Drives MCU SI or next device in daisy chain; changes on falling SCLK edge; high-Z when CSB = high |
| OUT1–OUT5 (Pins 42–43, 12–13, 39–41, 14–16, 28–37) | Protected high-side outputs | Each drives load to VPWR; integrated overload, overtemperature, and undervoltage protection; OUT3–OUT5 have lower RDS(on) |
| CSNS (Pin 45) | Analog feedback output | Provides voltage proportional to selected channel current, VPWR, or die temperature; SPI-programmable multiplexer source |
| SYNCB (Pin 46) | Current sense sync | Open-drain output synchronized to CSNS sampling; enables precise MCU ADC timing for current measurement |
| IN1–IN4 (Pins 47–50) | Direct control inputs | Wake device and control OUT1–OUT4 in Fail mode; internal pull-down; logic-high required for activation |
| LIMP (Pin 51) | Fail-mode trigger | Asserting high forces immediate transition to Fail mode; internal pull-down; used for system-level safety interlock |
| RSTB (Pin 4) | Reset input | Active-low initialization; clears SPI registers and faults; internal pull-down; deglitched (10 μs typical) |
Key Features
| Feature | Design Value |
|---|---|
| Penta-channel high-side switching | Five independently controlled, self-protected outputs with channel-specific RDS(on) (7.0/17 mΩ) optimize efficiency vs. load type |
| Programmable current sense | CSNS pin reports selectable analog signal (load current, VPWR, or temperature) with SPI-configurable gain and synchronization |
| Dual-mode operation | Normal mode (SPI-controlled PWM) and Fail mode (direct INx control) ensure functional safety compliance without MCU dependency |
| Reverse polarity & ground disconnect | Withstands –16 V VPWR; automatically activates outputs during reverse-battery events to limit power dissipation in incandescent loads |
| Ultra-low sleep current | < 5.0 μA VPWR consumption enables long-term battery-powered operation in always-on vehicle modules |
| PCB footprint compatibility | Shares SOIC-54-EP mechanical layout and SPI software driver with MC07XSG517EK and other MC32XSG variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC07XSG517EK | Identical electrical specs and pinout; differs only in tape-and-reel packaging (no R2 suffix) | No functional difference; suitable for same PCB designs and firmware | Select MC07XSG517EK for tray or non-R2 reel orders; MC07XSG517DEKR2 is the R2 tape-and-reel variant |
| MC17XSG500DEK | 32-pin SOIC-EP package; uniform 17 mΩ RDS(on) across all five channels; no 7.0 mΩ low-RDS(on) outputs | Better suited for space-constrained designs where uniform channel performance is prioritized over mixed-load optimization | Choose MC17XSG500DEK when board area is critical and all loads require identical RDS(on); not drop-in due to different pin count and layout |
Compared with MC07XSG517EK, MC07XSG517DEKR2 offers identical functionality in tape-and-reel format for automated assembly, while MC17XSG500DEK provides a smaller footprint at the cost of channel-specific RDS(on) flexibility - making MC07XSG517DEKR2 optimal for mixed-load systems requiring both high-current and precision-switching capability.

FAQ
What is the maximum continuous output current supported by MC07XSG517DEKR2?
MC07XSG517DEKR2 supports up to 11 A continuous current on OUT3/OUT4/OUT5 (7.0 mΩ RDS(on)) and 5.5 A on OUT1/OUT2 (17 mΩ RDS(on)), assuming junction temperature remains ≤125 °C using a four-layer board with RΘJA = 17.4 °C/W. Actual current depends on PCB copper area, airflow, and ambient temperature.
Does MC07XSG517DEKR2 support daisy-chained SPI communication?
Yes, MC07XSG517DEKR2 supports daisy-chained SPI communication via its SO pin, which connects directly to the SI pin of the next device. This enables control and diagnostics of multiple MC07XSG517DEKR2 units using a single MCU SPI port, reducing GPIO usage and simplifying firmware architecture.
How does MC07XSG517DEKR2 handle reverse battery conditions?
MC07XSG517DEKR2 withstands –16 V reverse polarity on VPWR. During reverse-battery events, internal protection activates OUT1–OUT5 to minimize power dissipation in incandescent bulbs, and clamping circuits prevent damage. No external reverse-protection diode is required.
What is the function of the SYNCB pin on MC07XSG517DEKR2?
The SYNCB pin on MC07XSG517DEKR2 is an open-drain output that synchronizes the MCU's ADC sampling with CSNS analog feedback updates. It ensures accurate current or voltage measurements by aligning conversion timing with the internal current-sense multiplexer switching event.
Can MC07XSG517DEKR2 operate without VCC applied?
No, MC07XSG517DEKR2 requires VCC (4.5–5.5 V) for SPI communication, SO output, CLK pin functionality, and OUT6 driver operation. While VPWR powers internal regulators and analog blocks, absence of VCC disables bidirectional SPI, preventing configuration, diagnostics, and OUT6 control - though basic high-side switching (OUT1–OUT5) remains possible in Fail mode if wake signals are asserted.
