Product details
Overview
MFS5600AVMADEPR2 from NXP Semiconductors is an automotive-grade dual-output power management IC integrating a 3.3 V/450 kHz internal-FET buck regulator (SW1) and a 3.3 V/450 kHz external-FET buck controller (SW2), with independent voltage monitors, windowed watchdog timer, PGOOD outputs, and ASIL B functional safety compliance for industrial-temperature applications (–40 °C to 105 °C).
For engineers reviewing the MFS5600AVMADEPR2 datasheet, MFS5600AVMADEPR2 pinout, MFS5600AVMADEPR2 application, or MFS5600AVMADEPR2 equivalent, this device supports precise low-noise power sequencing in ADAS sensor modules, telematics gateways, and radar front-ends where dual regulated rails, fault monitoring, and thermal robustness up to 150 °C junction are required.
Technical Context
The MFS5600AVMADEPR2 implements two independent synchronous buck topologies: SW1 uses integrated 105 mΩ high-side and 46 mΩ low-side MOSFETs delivering up to 3 A with ±2 % output accuracy; SW2 provides gate drive for external FETs supporting up to 15 A load, configurable via SW2FB feedback and SW2COMP compensation network.
Functional safety is enforced through dual PGOOD outputs, ERRMON/FCCU interface monitoring, and OTP-programmable windowed watchdog timer - all validated per AEC-Q100 Grade-1 and rated for industrial ambient (–40 °C to 105 °C) with 150 °C max junction temperature.

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 3.3 V/3 A buck with integrated FETs; no second controller channel or voltage monitors | Lacks SW2 controller, watchdog, and VMON - unsuitable for safety-critical dual-rail systems | Select only for cost-sensitive non-safety applications requiring single-rail 3.3 V supply |
| TPS65381A-Q1 | Triple-buck PMIC with 5 V/3.3 V/1.2 V outputs; includes SPI interface and enhanced ASIL D diagnostics | Higher pin count (48-QFN), larger footprint, and higher BOM cost; requires SPI configuration instead of OTP | Prefer when triple-rail support, ASIL D compliance, or diagnostic traceability beyond ASIL B is required |
Compared with MPQ4333-AEC1 and TPS65381A-Q1, the MFS5600AVMADEPR2 uniquely balances dual-buck flexibility, ASIL B safety features, and industrial-temperature operation in a compact 5 mm × 5 mm QFN - making it optimal for space-constrained telematics and radar modules needing verified fault monitoring without SPI overhead.

FAQ
What is the operating temperature range for the MFS5600AVMADEPR2?
The MFS5600AVMADEPR2 is rated for industrial ambient operation from –40 °C to 105 °C, with a maximum junction temperature of 150 °C. This rating is validated per AEC-Q100 Grade-1 test conditions and supports under-hood and chassis-mounted applications where extended thermal resilience is required. The MFS5600AVMADEPR2 achieves this via optimized thermal pad layout and internal thermal shutdown circuitry.
Does the MFS5600AVMADEPR2 support programmable output voltages?
Yes, the MFS5600AVMADEPR2 supports OTP-programmable output voltages for both SW1 and SW2. For SW1, OTP_SW1_VOLT[7:0] bits configure 1.8 V to 8.0 V outputs; the MFS5600AVMADEPR2 is factory-programmed for 3.3 V. SW2 output is set externally via resistor divider on SW2FB, with feedback reference of 1.0 V - allowing precise 3.3 V regulation matching the SW1 rail.
How does the windowed watchdog timer function in the MFS5600AVMADEPR2?
The MFS5600AVMADEPR2 implements a windowed watchdog timer that requires service pulses within a defined time window - not just periodic pulses - to prevent false timeouts during transient delays. It is enabled by default in ASIL B variants and monitored via the ERRMON interface. While the MFS5600AVMADEPR2 is a QM-grade part, its underlying architecture includes the watchdog logic; however, the windowed watchdog is disabled in QM versions per Table 1 of the datasheet.
Can the MFS5600AVMADEPR2 be used in automotive applications requiring ASIL B compliance?
The MFS5600AVMADEPR2 is a QM-grade variant of the FS5600 family and does not include ASIL B safety features such as the windowed watchdog timer, ERRMON/FCCU monitoring, or LBIST. It shares the same package and pinout as ASIL B versions but omits those functions. For ASIL B systems, engineers must select MFS5600AMBAFES or equivalent ASIL B–rated variants - the MFS5600AVMADEPR2 is intended for industrial and non-safety-critical automotive applications.
What external components are required for stable operation of the MFS5600AVMADEPR2?
The MFS5600AVMADEPR2 requires four key external components per regulator: (1) input capacitor (≥10 µF X5R/X7R on SW1IN/VIN), (2) output capacitor (2×22 µF X5R/X7R on SW1OUT), (3) bootstrap capacitor (0.1 µF ceramic between SW1BOOT/SW1LX), and (4) output inductor (6.8 µH for 450 kHz operation). All bypass capacitors must be placed within 3 mm of respective pins to ensure stability and EMI performance.
