Product details
Overview
MFS5600AMMA8ES from NXP Semiconductors is a QM-grade automotive dual-output power management IC integrating a 3.3 V/450 kHz internal-FET buck regulator (SW1) and a 5.0 V/450 kHz external-FET buck controller (SW2), with ±2 % output accuracy, AEC-Q100 Grade-1 qualification, and operation from –40 °C to 150 °C junction temperature - deployed in infotainment and telematics power domains.
For engineers reviewing the MFS5600AMMA8ES datasheet, MFS5600AMMA8ES pinout, MFS5600AMMA8ES application, or MFS5600AMMA8ES equivalent, this device requires attention to OTP-configured output voltages, QM-specific pin mapping (no VMON1/VMON2/FS0B), SW1/SW2 enable sequencing, and thermal vias on the EPAD for automotive under-hood reliability.
Technical Context
The MFS5600AMMA8ES implements two independent switching regulators: SW1 uses peak-current-mode control with integrated high- and low-side MOSFETs (RDS(on) = 105 mΩ / 46 mΩ), programmable soft-start (337–4000 µs), and selectable PFM/PWM mode; SW2 employs external FETs with differential current sensing (SW2CSN/SW2CSP), gate drivers supporting up to 15 A load, and adjustable compensation via SW2COMP.
It operates across 4.4 V–36 V input (BIAS_IN = 0 V) or 2.7 V–36 V (BIAS_IN = 5 V), delivers regulated VDIG (1.6 V) and VCC (4.7 V), and features I²C interface (SCL/SDA), three GPIOs (GPIO1/VDDOTP, VMON4/GPIO3, VMON3/GPIO2), and dual open-drain PGOOD outputs - all in a 32-pin 5 mm × 5 mm WF-QFN package with exposed thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SW1 Output | 3.3 V @ 450 kHz, ±2 % accuracy - fixed by OTP; no external resistor divider required. |
| SW2 Output | 5.0 V @ 450 kHz - configured via external feedback resistors on SW2FB. |
| Input Voltage Range | 4.4 V to 36 V (no BIAS_IN) - supports cold-crank down to 4.4 V without shutdown. |
| Quiescent Current | 12.5 µA typical (SW1 active, SW2 disabled, ULPM mode) - enables low-power always-on domains. |
| Thermal Rating | Junction temperature range –40 °C to 150 °C - validated for under-hood automotive placement. |
| Package | 32-pin WF-QFN, 5 mm × 5 mm, 0.5 mm pitch, exposed EPAD - requires ≥4 thermal vias to ground. |
| Safety Grade | QM (Quality Management) - no built-in watchdog, voltage monitors, or FS0B; safety-critical functions omitted. |
Pinout & Package
Package: 32-pin Wettable Flank QFN (WF-QFN), 5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad (EPAD). Requires solder mask defined pads and ≥4 thermal vias connected to solid ground plane for thermal reliability in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDDIO | I²C I/O supply | Bypass with 0.1 µF to VCC; sets logic level for SCL/SDA (1.8 V or 3.3 V compatible). |
| 2 SCL / 3 SDA | I²C interface | Configurable for OTP programming, register read/write, and fault reporting; pull-up to VDDIO required. |
| 4 GPIO1/VDDOTP | General-purpose I/O / OTP supply | Used as VDDOTP during development; functions as GPO in production; connect to ground if unused. |
| 13 VMON4/GPIO3 / 14 VMON3/GPIO2 | Configurable GPIOs | QM version supports only GPO functionality (no voltage monitoring); both pins default to push-pull outputs. |
| 17 SW1BOOT / 20–21 SW1LX / 23 EN1 | SW1 power stage control | Bootstrap capacitor between SW1BOOT–SW1LX; EN1 high enables 3.3 V regulator; SW1LX connects to inductor. |
| 25 SW1FB / 26 PGOOD1 / 27 PGOOD2 | Feedback & status outputs | SW1FB tied directly to 3.3 V output (internal divider); PGOOD1/PGOOD2 are open-drain, require pull-ups. |
| 32 VIN / 30 VCC / 28 VDIG / 29 BIAS_IN | Power inputs & supplies | VIN powers internal circuitry (4.4–36 V); VCC ≈ 4.7 V (no external load); VDIG = 1.6 V (logic supply, no load); BIAS_IN optional 5 V bias. |
| EPAD | Thermal & electrical ground | Mandatory connection to PCB ground plane via ≥4 thermal vias; primary path for heat dissipation and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 3.3 V buck regulator (SW1) | Delivers up to 3 A continuous load with internal FETs; eliminates need for external power stage components. |
| 5.0 V buck controller (SW2) | Drives external high- and low-side MOSFETs with 900 mA gate drive capability for scalable 15 A output. |
| OTP-programmable configuration | Fixed 3.3 V/5.0 V outputs, soft-start time, PFM on-time, and minimum on-time set at factory - no runtime reconfiguration. |
| Automotive-qualified thermal performance | RθJA = 29.4 °C/W (2s6p layout); supports sustained 150 °C junction operation in engine compartment placements. |
| Low-quiescent-current ULPM mode | 12.5 µA typical (SW1 active, SW2 off) enables always-on microcontroller domains without battery drain. |
| QFN with wettable flanks | Enables automated optical inspection (AOI) of solder joints - critical for zero-defect automotive manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive dual-buck power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MFS5600AMBAFES | ASIL B grade; includes windowed watchdog timer, 4x external voltage monitors, FS0B fail-safe output, ERRMON/FCCU monitoring. | Required for ASIL B system compliance; supports safety mechanisms like periodic self-test (ABIST) and fault reporting. | Select when functional safety certification (ISO 26262) is mandatory; not drop-in - requires VMON routing, watchdog initialization, and FS0B handling. |
| MFS5600AMBAYES | ASIL B grade; same 5.0 V/450 kHz SW2 but 3.3 V/450 kHz SW1; adds LBIST and I²C CRC for enhanced diagnostics. | Targeted at higher-integrity ADAS domains needing diagnostic coverage beyond basic ASIL B. | Choose for systems requiring logic-level BIST and communication integrity; requires updated OTP programming flow and safety software integration. |
Compared with MFS5600AMMA8ES, the ASIL B alternatives add safety infrastructure (watchdog, monitors, FS0B, ABIST/LBIST) at the cost of increased design complexity and non-drop-in pin usage - making MFS5600AMMA8ES optimal for QM-tier infotainment and telematics where safety hardware is implemented externally.

FAQ
What output voltages are factory-programmed in the MFS5600AMMA8ES?
The MFS5600AMMA8ES is pre-programmed with SW1 set to 3.3 V at 450 kHz and SW2 configured for 5.0 V at 450 kHz. These values are stored in OTP memory and cannot be altered in the field. SW1 uses its internal resistor divider, so SW1FB must be connected directly to the 3.3 V output; SW2 requires an external resistor divider on SW2FB to achieve 5.0 V regulation.
Does the MFS5600AMMA8ES include a watchdog timer or voltage monitors?
No, the MFS5600AMMA8ES is the QM (Quality Management) variant and excludes all functional safety features. It does not contain a windowed watchdog timer, external voltage monitors (VMON1–VMON4), FS0B output, ERRMON/FCCU monitoring, ABIST, or LBIST. Pins VMON1, VMON2, and FS0B are NC and must be grounded per datasheet guidance.
What is the minimum input voltage required for the MFS5600AMMA8ES to operate reliably?
The MFS5600AMMA8ES requires a minimum input voltage of 4.4 V when BIAS_IN is unconnected, and 2.7 V when BIAS_IN is supplied with 5 V. This 4.4 V threshold supports automotive cold-crank conditions. Below this voltage, the device shuts down - confirmed by the VIN_r parameter (max 5.7 V) and operating range specifications in the datasheet.
Can the MFS5600AMMA8ES be used with external MOSFETs for both SW1 and SW2?
No. SW1 is a fully integrated buck regulator with internal high- and low-side MOSFETs (RDS(on) = 105 mΩ / 46 mΩ) and cannot drive external FETs. Only SW2 is a controller architecture - it provides dedicated gate drive outputs (SW2GHS, SW2GLS), current sense inputs (SW2CSP/SW2CSN), and compensation pin (SW2COMP) explicitly for external FETs.
How is thermal management handled on the MFS5600AMMA8ES package?
The MFS5600AMMA8ES uses a 32-pin WF-QFN with an exposed EPAD that must be soldered to a solid PCB ground plane. Thermal performance relies on ≥4 thermal vias under the EPAD connecting to internal ground layers. With a 2s6p board layout, RθJA is 29.4 °C/W - enabling full 150 °C junction operation when ambient is ≤125 °C and power dissipation remains within safe limits.
