Product details
Overview
MC34FS6407NAER2 from NXP Semiconductors is a power system basis chip integrating a high-speed CAN transceiver (ISO 11898-2/5 compliant), SMPS pre-regulator, 0.8 A VCORE switching regulator, dual linear regulators (VCCA and VAUX), six configurable I/Os, and fail-safe supervision logic - designed for industrial safety-critical systems operating from 2.7 V to 36 V input.
For engineers reviewing the MC34FS6407NAER2 datasheet, MC34FS6407NAER2 pinout, MC34FS6407NAER2 application, or MC34FS6407NAER2 equivalent, key selection criteria include its 0.8 A VCORE output capability, LQFP-48 EP package with exposed thermal pad, integrated HSCAN transceiver with ±27 V bus fault tolerance, low-power mode current of 32 µA, and six wake-up-capable I/Os supporting safety monitoring in PLCs and mobile machinery.
Technical Context
The MC34FS6407NAER2 implements a dual-stage power architecture: a highly flexible SMPS pre-regulator (buck or non-inverting buck-boost) generating VPRE (6.25 V typical), followed by a dedicated VCORE SMPS delivering up to 0.8 A at 1.2–3.3 V with FB_CORE feedback and COMP_CORE compensation. Its fail-safe machine monitors VPRE, VCORE, VCCA, and VAUX voltages with programmable thresholds and hysteresis, asserting FS0B and RSTB outputs on fault detection.
Integrated HSCAN transceiver supports high-speed CAN communication with TXD/RXD SPI-controlled logic interface, CANH/CANL differential outputs (±27 V common-mode range), and sleep-mode wake-up via bus activity. Six digital I/Os (IO_0–IO_5) provide load-dump-proof inputs with edge-selectable wake-up and gate-driver capability for external NMOS, all managed via SPI register access.

FAQ
What is the maximum output current capability of the VCORE regulator in MC34FS6407NAER2?
The VCORE regulator in MC34FS6407NAER2 delivers up to 0.8 A continuously in normal operating mode, as specified in Table 4 of the NXP FS6407/FS6408 datasheet Rev. 3.0. This output is adjustable from 1.2 V to 3.3 V using external feedback resistors on FB_CORE, and includes overcurrent limiting (1–2 A threshold) and thermal shutdown at 160 °C to protect the device under fault conditions. The MC34FS6407NAER2 is rated for this 0.8 A capability across its full -40 °C to 125 °C ambient temperature range.
Does MC34FS6407NAER2 support both buck and boost configurations for its pre-regulator?
Yes, MC34FS6407NAER2 supports two distinct SMPS pre-regulator topologies: standard buck and non-inverting buck-boost. The buck configuration operates when input voltage exceeds ~4.6 V, while the buck-boost mode enables regulation down to 2.7 V input - critical for cold-cranking scenarios in 12 V systems. Selection is determined by external component placement (e.g., inductor and diode routing), not firmware; Figure 1 and Figure 2 in the datasheet show both application schematics. The VPRE output remains stable at 6.25 V in either mode.
How does the fail-safe supervision block in MC34FS6407NAER2 operate?
The fail-safe supervision block in MC34FS6407NAER2 independently monitors VPRE, VCORE, VCCA, and VAUX voltages using dedicated comparators with programmable thresholds and hysteresis. Upon detecting undervoltage, overvoltage, or overtemperature (160 °C), it asserts the open-drain FS0B pin low and drives RSTB low to reset the connected MCU. These outputs remain active until the fault clears and the internal state machine completes recovery - ensuring deterministic behavior for ASIL-B safety partitioning without software intervention.
What are the key electrical specifications of the integrated CAN transceiver in MC34FS6407NAER2?
The integrated CAN transceiver in MC34FS6407NAER2 complies with ISO 11898-2 and ISO 11898-5, featuring differential output voltage (VOH-VOL) of 1.5–3.0 V in dominant state, ±27 V common-mode bus fault tolerance, and ESD robustness of ±8 kV HBM on CANH/CANL pins. It supports data rates up to 1 Mbps, includes bus wake-up capability in sleep mode, and provides CAN_5V (4.8–5.2 V) regulated supply for external CAN PHY isolation if needed - all within the same die as the power management functions.
Can the six I/O pins (IO_0 through IO_5) on MC34FS6407NAER2 be used simultaneously as both inputs and outputs?
No - each of the six I/O pins (IO_0–IO_5) on MC34FS6407NAER2 is configurable via SPI register settings as either a digital input (with load-dump protection and edge-selectable wake-up) or an output gate driver for external low-side NMOS transistors, but not both simultaneously. IO_4 and IO_5 are designated as gate drivers; IO_0–IO_3 support analog input multiplexing via MUX_OUT. Configuration is static per power cycle and requires SPI write to the appropriate control register - preventing concurrent bidirectional use on any single pin.
