Product details
Overview
MFS5600AMMA0ESR2 from NXP Semiconductors is a QM-grade automotive dual-buck power management IC integrating a 3 A internal-FET buck regulator (SW1) and a 15 A external-FET buck controller (SW2), with ±2 % output accuracy, 250 kHz–3 MHz programmable switching frequency, and operation across –40 °C to 150 °C junction temperature - deployed in infotainment and ADAS domain controllers requiring functional safety-aware power sequencing.
For engineers reviewing the MFS5600AMMA0ESR2 datasheet, MFS5600AMMA0ESR2 pinout, MFS5600AMMA0ESR2 application, or MFS5600AMMA0ESR2 equivalent, key selection considerations include its QM safety grade (no windowed watchdog or external voltage monitors), 32-pin 5 mm × 5 mm WF-QFN package, dual-regulator architecture with independent enable/control, and OTP-programmable SW1 output voltage (e.g., 5.0 V @ 450 kHz per ordering info).
Technical Context
The MFS5600AMMA0ESR2 implements two independent buck topologies: SW1 uses peak-current-mode control with integrated high- and low-side FETs (RDS(on) = 105 mΩ / 46 mΩ), internal current sensing, and programmable soft-start (337–4000 µs); SW2 employs external MOSFETs driven by dedicated gate outputs (SW2GHS/SW2GLS), current-sense inputs (SW2CSP/SW2CSN), and compensation (SW2COMP) for up to 15 A load capability.
It operates from 2.7 V to 36 V input, supports PFM/PWM mode selection via MODE/SYNCIN or OTP, includes I²C interface (SCL/SDA) with CRC support, and integrates safety-critical logic such as ABIST, thermal shutdown, and PGOOD monitoring - though the QM variant omits ERRMON, FCCU, FS0B, VMON1–VMON4, and Challenger Watchdog features present in ASIL B versions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 36 V - supports direct connection to reverse-protected automotive battery, including load-dump tolerance up to 36 V. |
| SW1 Output Capability | Up to 3 A continuous load at ±2 % accuracy - enables powering core SoCs or microcontrollers without external FETs. |
| SW2 Controller Drive | 900 mA gate drive with dedicated high/low-side outputs - supports discrete external MOSFETs for scalable 15 A output. |
| Switching Frequency | 250 kHz to 3 MHz (OTP-programmable) - allows EMI optimization and inductor size reduction in space-constrained automotive modules. |
| Operating Temperature | –40 °C to 150 °C TJ - qualified for under-hood and domain controller environments per AEC-Q100 Grade-1. |
| Package | 32-pin WF-QFN, 5 mm × 5 mm - thermally enhanced with EPAD grounding for high-power density layout. |
| Quiescent Current | 16 µA typical (ULPM mode, both regulators in PFM) - extends battery life during vehicle sleep states. |
Pinout & Package
Package: 32-pin Wettable Flank QFN (WF-QFN), 5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad (EPAD). Pinout conforms to QM version (Figure 5): pins VMON1–VMON4, FS0B, and ERRMON/FCCU monitoring functions are not implemented; GPIO1/VDDOTP serves only as general-purpose I/O or OTP supply during development.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 32) | Main power input | Supplies internal circuitry; must be connected to reverse-protected battery rail (2.7–36 V). |
| SW1IN (Pins 18,19) | SW1 power input | Bypassed with ≥10 µF capacitor; feeds integrated FETs of SW1 buck regulator. |
| SW1FB (Pin 25) | SW1 feedback | Connects directly to SW1 output (internal divider) or to resistor divider (external divider) for OTP-configured voltage. |
| EN1 (Pin 23) | SW1 enable | Active-high logic input; rising threshold 1.4 V - controls startup timing and sequencing with other rails. |
| SCL/SDA (Pins 2,3) | I²C interface | Configurable for OTP programming, register read/write, and status monitoring; pulled up to VDDIO (1.8/3.3 V). |
| PGOOD1/PGOOD2 (Pins 26,27) | Power-good outputs | Open-drain signals indicating regulated output status; used for system power sequencing and fault detection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-buck architecture | Combines fixed 3 A integrated regulator (SW1) and scalable 15 A controller (SW2) in one die - reduces board area vs. discrete solutions. |
| OTP-programmable configuration | SW1 output voltage (1.8–8.0 V), soft-start time (337–4000 µs), PFM on-time (160–800 ns), and min on-time (40–100 ns) set once during production - eliminates external resistors and simplifies BOM. |
| Automotive-grade reliability | AEC-Q100 Grade-1 qualified, 8 kV contact ESD (IEC61000-4-2), and –40 °C to 150 °C TJ operation - meets harsh automotive environmental requirements. |
| Low-quiescent-current modes | 16 µA typical ULPM current with both regulators in PFM - enables <100 µA system sleep current when paired with ultra-low-IQ downstream loads. |
| Thermally optimized package | 32-pin WF-QFN with EPAD and 29.4 °C/W RθJA (2s6p layout) - supports >2 W dissipation without forced airflow in compact ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-buck automotive power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 | Single 3 A buck regulator with integrated FETs; no secondary controller channel or I²C interface. | Lacks SW2 controller, voltage monitors, and functional safety logic - suitable only for simpler single-rail applications. | Select when only one regulated rail is needed and system-level safety compliance is handled externally. |
| TPS65381A-Q1 | Triple-buck + LDO PMIC with ASIL B certification, built-in watchdog, and more extensive voltage monitoring (6 channels). | Includes ASIL B safety mechanisms (windowed watchdog, LBIST) and additional rails - higher cost and complexity. | Choose when full ASIL B compliance is required and multi-rail flexibility outweighs QM-grade cost advantage of MFS5600AMMA0ESR2. |
Compared with MPQ4333-AEC1, MFS5600AMMA0ESR2 adds a scalable second buck controller and I²C configurability; versus TPS65381A-Q1, it trades ASIL B safety features for lower cost and smaller footprint in QM-tier systems where external safety layers exist.

FAQ
What safety grade does MFS5600AMMA0ESR2 support?
MFS5600AMMA0ESR2 is a QM (Quality Management) grade device - it lacks windowed watchdog timer, external voltage monitors (VMON1–VMON4), FS0B fail-safe output, and ERRMON/FCCU monitoring found in ASIL B variants. It is intended for non-safety-critical subsystems where functional safety is managed at the system level, not the IC level.
Does MFS5600AMMA0ESR2 support programmable output voltages?
Yes, MFS5600AMMA0ESR2 supports OTP-programmable SW1 output voltage from 1.8 V to 8.0 V in 50 mV steps (e.g., 5.0 V or 3.3 V), configured during production using NXP's GUI and socketed evaluation board. SW2 output is set externally via resistor divider on SW2FB.
What is the maximum load current supported by the integrated SW1 regulator in MFS5600AMMA0ESR2?
The integrated SW1 regulator in MFS5600AMMA0ESR2 delivers up to 3 A continuous output current with ±2 % accuracy. Peak current limit is configurable via OTP (1.5 A to 8 A), and 3.5 A can be drawn transiently without entering current limit under typical conditions.
Can MFS5600AMMA0ESR2 operate with a 40 V input transient?
No - MFS5600AMMA0ESR2 has an absolute maximum input rating of 40 V on VIN, SW1IN, and SW2LX pins, but its recommended operating range is 2.7 V to 36 V. Sustained operation above 36 V risks damage; it is rated for short-duration load-dump events up to 36 V per AEC-Q100.
Is I²C communication supported on MFS5600AMMA0ESR2 for runtime configuration?
Yes, MFS5600AMMA0ESR2 includes full I²C interface (SCL/SDA pins) supporting OTP emulation during development and real-time register access for status monitoring (e.g., PGOOD, thermal flag) and mode control - though OTP programming for production must be performed by NXP or authorized partners.
