Product details
Overview
MC33FS8415G0ESR2 from NXP Semiconductors is an ASIL B–capable automotive fail-safe system basis chip (SBC) integrating a VPRE synchronous buck controller, one integrated low-voltage synchronous BUCK1 (1.1 V, 4.5 A peak), one integrated BUCK3 (2.3 V, 4.5 A peak), 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 serves as the primary power management and safety monitor for radar modules with NXP S32R294 + TEF810x in 12 V/24 V applications.
For engineers reviewing the MC33FS8415G0ESR2 datasheet, MC33FS8415G0ESR2 pinout, MC33FS8415G0ESR2 application, or MC33FS8415G0ESR2 equivalent, this page delivers verified functional architecture, validated safety features per ISO 26262, confirmed OTP-configured regulator settings, and real-world radar-system integration context - all aligned to the FS84 family's documented FS8415 variant specifications.
Technical Context
The MC33FS8415G0ESR2 implements a dual-domain power architecture: VPRE controls external high-side MOSFETs for primary 12 V/24 V input conditioning, while BUCK1, BUCK3, BOOST, LDO1, and LDO2 deliver tightly regulated, sequenced rails to MCU cores, I/Os, ADCs, and RF front-ends. Its fail-safe state machine monitors VCOREMON, VMON1–VMON4, and FCCU inputs to assert FS0B on fault detection.
It supports both SPI and I2C (0x20 address) interfaces with CRC, includes frequency synchronization (FIN/FOUT), PSYNC for multi-device coordination, and integrates ABIST/LBIST for on-chip self-test. Power-up sequencing is fixed per OTP: BUCK1 starts in Slot 6, BUCK3 in Slot 0, LDO1 in Slot 2, and LDO2 in Slot 1.

Pinout & Package
MC33FS8415G0ESR2 uses the HVQFN56 package: plastic thermal-enhanced very thin quad flat package with wettable flank, 56 terminals, 0.5 mm pitch, 8 mm × 8 mm × 0.85 mm body, and exposed pad (EP) connected to GNDFS/GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (WAKE2) | Wake-up input 2 | Digital/analog input for system wake from OFF mode; requires external series resistor if used globally |
| 14 (FS0B) | Fail-safe output 0 | Active-low open-drain signal asserting system-level fault; drives external safety relay or MCU interrupt |

| 56 (LDO1_IN) | LDO1 input | Accepts pre-regulated input (e.g., from BUCK3 or VBOOST); decoupling required per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configurable power sequencing | Fixed startup order across 6 slots: BUCK1 (Slot 6), BUCK3 (Slot 0), LDO1 (Slot 2), LDO2 (Slot 1) - eliminates external sequencing IC |
| EMC-optimized SMPS control | Includes frequency synchronization (FIN/FOUT), spread spectrum, slew rate control, and manual tuning - reduces radiated emissions in radar bands |
| Fail-safe state machine | Monitors 5 independent voltage rails (VCOREMON, VMON1–VMON4), temperature, and FCCU signals; asserts FS0B within <250 µs of fault detection |
| Multi-interface communication | Supports both SPI (4-wire) and I2C (0x20) with CRC error checking - enables redundancy or interface selection during system design |
| Deep fail-safe autoretry | FS0B remains asserted with infinite retry cycles until fault clears; prevents unsafe recovery without host MCU intervention |
| OFF mode quiescent current | 10 µA typical - meets automotive cold-cranking and parking-mode current budget requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33FS8410G0ES | No FCCU monitoring; only 2 VMON inputs (VMON1/VMON2); no BUCK3; BUCK1 starts in Slot 0 | Targeted for simpler camera modules without radar PHY or multi-rail safety monitoring | Select when ASIL B safety scope is limited to core + I/O rails only, and FCCU/ERRMON interfaces are unused |
| MC33FS8420G0ES | Includes BUCK2 (1.8 V/4.5 A) instead of BUCK3; BUCK2 multiphase-capable with BUCK1; no FCCU | Optimized for dual-core MCU platforms requiring higher I/O current or parallel regulation | Choose when system requires >4.5 A on a single low-voltage rail and does not need BOOST or FCCU-level MCU health monitoring |
Compared with MC33FS8410G0ES and MC33FS8420G0ES, the MC33FS8415G0ESR2 uniquely combines BUCK3 + BOOST + FCCU + 4× VMON monitoring in a single ASIL B SBC - making it the only FS84 variant qualified for radar subsystems requiring simultaneous RF bias, core/I/O regulation, and MCU error signaling.

FAQ
What safety certifications apply to the MC33FS8415G0ESR2?
The MC33FS8415G0ESR2 is developed in compliance with ISO 26262 for ASIL B applications and qualified per AEC-Q100 Rev H Grade 1 (−40 °C to +125 °C ambient). It includes built-in ABIST/LBIST, fail-safe state machine, and hardware-monitored voltage rails - all documented in the FS84_FS85C product data sheet Rev. 12.0.
Does the MC33FS8415G0ESR2 support both SPI and I2C interfaces simultaneously?
No - the MC33FS8415G0ESR2 supports either SPI or I2C, selected at boot via OTP configuration. Its I2C address is fixed at 0x20; SPI uses standard 4-wire protocol with CSB, SCLK, MOSI, and MISO. Interface selection is immutable after OTP programming.
What is the function of the PSYNC pin on the MC33FS8415G0ESR2?
The PSYNC pin on the MC33FS8415G0ESR2 operates as a bidirectional power synchronization signal. It allows two MC33FS8415G0ESR2 devices - or one MC33FS8415G0ESR2 plus an external PMIC - to align switching frequencies and phase-shifted operation, reducing system-level conducted and radiated noise in radar-sensitive environments.
How is the fail-safe output (FS0B) triggered on the MC33FS8415G0ESR2?
The FS0B pin on the MC33FS8415G0ESR2 asserts low within ≤250 µs upon detection of any monitored fault: VCOREMON UV/OV, VMON1–VMON4 threshold violation, TSD, FCCU1/FCCU2 error, or ERRMON assertion. It remains latched in infinite autoretry mode until the root cause is cleared and the device resets.
Can the MC33FS8415G0ESR2 be used in 24 V commercial vehicle applications?
Yes - the MC33FS8415G0ESR2 supports up to 60 V DC input and is qualified for 12 V and 24 V automotive applications. Its VSUP1/VSUP2 pins require external reverse-battery protection diodes, and its VPRE controller is configured for 3.3 V output at 455 kHz - validated for use with NXP S32R294 + TEF810x in 24 V radar systems per ordering table notes.
