Product details
Overview
MC33FS8415G0KSR2 from NXP Semiconductors is an ASIL B–capable automotive fail-safe system basis chip (SBC) integrating a VPRE synchronous buck controller, one low-voltage integrated synchronous BUCK1 (1.1 V/4.5 A), one BUCK3 (2.3 V/4.5 A), a BOOST converter (5.0 V/1.5 A peak), and two LDOs (LDO1: 1.8 V/400 mA; LDO2: 3.3 V/400 mA). It supports radar and ADAS domain controllers with external frequency synchronization, spread-spectrum EMC optimization, and fail-safe output for safety-critical power sequencing.
For engineers reviewing the MC33FS8415G0KSR2 datasheet, MC33FS8415G0KSR2 pinout, MC33FS8415G0KSR2 application, or MC33FS8415G0KSR2 equivalent, this device delivers configurable multi-rail power management with SPI/I²C control, thermal shutdown protection, deep fail-safe autoretry, and OTP-programmable power-up sequencing - critical for radar sensor modules requiring functional safety compliance and low EMI.
Technical Context
The MC33FS8415G0KSR2 implements a dual-domain safety architecture: dedicated monitoring circuitry (FCCU, ABIST, ERRMON) validates MCU health and regulator outputs, while independent fail-safe state machine asserts FS0B on fault detection. Its VPRE controller drives external high-side/low-side MOSFETs with programmable slew rate (PU/PD/900 mA) and slope compensation (50 mV/µs).
Power regulation includes BUCK1 (2.22 MHz, 1.1 V, 4.5 A peak, soft-start 7.81 mV/µs) and BUCK3 (2.22 MHz, 2.3 V, 4.5 A peak, soft-start 10.41 mV/µs), both assigned to specific power sequencing slots (Slot 0 and Slot 0 respectively), with TSD-triggered shutdown + DFS response. The device uses I²C (address 0x20) and SPI interfaces with CRC for configuration and monitoring.
Key Specifications

Pinout & Package
MC33FS8415G0KSR2 is housed in HVQFN56 (8 mm × 8 mm × 0.85 mm, 0.5 mm pitch, wettable flank), with exposed thermal pad (EP) connected to GNDFS/GND. Pin count and function match FS8415 variant per Figure 3 (FS8415 pin configuration) in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP1 / VSUP2 | Main power inputs | Accept 60 V DC input; require external reverse-battery diodes; feed internal regulators and bias circuits. |
| BUCK1_IN / BUCK1_SW / BUCK1_FB | BUCK1 power path | Supports 1.1 V/4.5 A output; FB pin enables closed-loop regulation; SW node connects to external inductor/diode. |
| BUCK3_IN / BUCK3_SW / BUCK3_FB | BUCK3 power path | Delivers 2.3 V/4.5 A; INQ pin provides quiet input sensing; FB enables precision feedback for stable load regulation. |
| VDDIO / VDDI2C | Digital supply rails | VDDIO powers SPI/FOUT/AMUX buffers (1.8–5.5 V compatible); VDDI2C supplies I²C level-shifters independently. |
| FS0B / PGOOD / RSTB | Failsafe & status outputs | FS0B (open-drain) asserts on fault; PGOOD and RSTB are active-low with mandatory VDDIO pull-up for MCU coordination. |
| SCL / SDA / MOSI / MISO / SCLK / CSB | Communication interfaces | Full SPI and I²C support with CRC; allows runtime reconfiguration, telemetry readback, and safety state reporting. |
| VCOREMON / VMON1–VMON4 | Monitoring inputs | VCOREMON tied to BUCK1 output for core voltage supervision; VMON1–VMON4 monitor external rails with programmable OV/UV thresholds and deglitch times. |
| PRE_GHS / PRE_GLS / PRE_SW / PRE_BOOT | VPRE gate drive | Drive external high-side/low-side MOSFETs; PRE_BOOT supplies bootstrap capacitor; PRE_SW is switching node for synchronous rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe state machine with FS0B | Asserts open-drain fail-safe output on detected faults (TSD, OV, UV, watchdog timeout), enabling system-level partitioning per ASIL B requirements. |
| Configurable power sequencing | Assigns BUCK1 and BUCK3 to Slot 0, enabling deterministic startup order without external timing components - critical for radar SoCs like S32R294. |
| EMC optimization suite | Includes SMPS frequency synchronization (FIN/FOUT), spread spectrum, slew rate control, and manual tuning - reduces radiated emissions in dense ADAS PCB layouts. |
| OTP-programmable safety parameters | Enables customer-specific OV/UV thresholds (e.g., VCOREMON UVTH = 95%), deglitch times (UV_DGLT = 25 µs), and fail-safe retry count (infinite autoretry). |
| Multi-interface digital control | Supports both SPI (with CRC) and I²C (0x20 address) for flexible integration into MCU-based diagnostics, calibration, and field updates. |
