Product details
Overview
MC33PF8201A0ES from NXP Semiconductors is an automotive-grade power management IC (PMIC) designed for i.MX 8-based high-performance applications. It integrates five high-efficiency buck converters (SW1–SW7, with SW7 independent), three linear regulators (LDO1–LDO3), RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL B safety monitoring circuitry. It powers CPU cores, GPU, DDR I/O, LPDDR memory, and peripherals in infotainment systems.
For engineers reviewing the MC33PF8201A0ES datasheet, MC33PF8201A0ES pinout, MC33PF8201A0ES application, or MC33PF8201A0ES equivalent, key selection considerations include its 56-pin HVQFN package, 3.4 MHz I²C interface, OTP-configurable startup sequence, dynamic voltage scaling on four bucks, and functional safety compliance per ASIL B requirements.
Technical Context
The MC33PF8201A0ES implements a deterministic state machine with fail-safe transitions, self-test capability (ABIST), and programmable fault response including FSOB assertion. Its architecture supports dual-phase configuration for SW1/SW2 and SW5/SW6, VTT termination on SW6, and spread-spectrum switching to reduce EMI.
It features 24-channel analog multiplexer for system diagnostics, independent voltage/thermal monitoring with programmable thresholds, and secure I²C write protection for safety-critical registers. The device operates across −40 °C to +105 °C ambient and supports fast startup via OTP-stored configuration.

FAQ
What is the primary application target for MC33PF8201A0ES?
MC33PF8201A0ES is specifically engineered for automotive infotainment and ADAS systems based on NXP i.MX 8 processors. It provides all required power rails-including CPU cores, GPU, DDR I/O, LPDDR memory, and peripherals-with ASIL B safety monitoring, OTP-configured sequencing, and failsafe signaling. Its design targets space-constrained, thermally demanding environments where reliability and functional safety are mandatory.
Does MC33PF8201A0ES support dynamic voltage scaling (DVS)?
Yes, MC33PF8201A0ES supports DVS on SW1, SW2, SW5, and SW6 buck converters. This allows real-time adjustment of output voltage under software control via the 3.4 MHz I²C interface, enabling power optimization during varying processor load states. DVS is implemented without external components, leveraging internal DACs and feedback loop reconfiguration.
How does MC33PF8201A0ES achieve ASIL B compliance?
MC33PF8201A0ES achieves ASIL B compliance through integrated safety mechanisms: independent voltage/thermal monitors with programmable thresholds, ABIST for analog self-test, CRC-protected safety registers, fail-safe output (FSOB), fault counters, and a deterministic state machine with fail-safe transition logic. These features are validated per ISO 26262 and documented in NXP's safety manual for PF8201.
What is the role of the FSOB pin on MC33PF8201A0ES?
The FSOB (Fail-Safe Output) pin on MC33PF8201A0ES is an open-drain output that asserts LOW during critical failures-such as thermal shutdown, multiple undervoltage events, or ABIST failure-to signal the host MCU to enter a safe state. Its behavior is configurable via OTP and is integral to the ASIL B safety architecture of MC33PF8201A0ES.
Can MC33PF8201A0ES power LPDDR4 memory interfaces?
Yes, MC33PF8201A0ES directly supports LPDDR4 interfaces via dedicated rails: SW6 in VTT termination mode supplies DDR VTT, while SW2 or SW5 can be configured for VDDQ (1.1 V), and LDO2 or LDO3 provide VDD2 (1.8 V) or VDD1 (3.3 V). Its 0.4 V–1.8 V buck range, 6.25 mV steps, and ±1.5 % accuracy meet JEDEC LPDDR4 voltage tolerance requirements.
