Product details
Overview
MC33PF3000A5ESR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6SL application processors with LPDDR2 memory. It integrates four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including VCC_SD (100 mA, dual-voltage), V33 (350 mA), and VSNVS (1.0 mA), plus DDR reference (VREFDDR) and coin-cell charging. It powers full system rails in portable industrial and consumer edge devices.
For engineers reviewing the MC33PF3000A5ESR2 datasheet, MC33PF3000A5ESR2 pinout, MC33PF3000A5ESR2 application, or MC33PF3000A5ESR2 equivalent, this page delivers verified regulator configurations, OTP-programmable startup sequencing, I²C-address flexibility (0x08–0x0F), dynamic voltage scaling support, and wettable-flank QFN package details - all specific to the A5 configuration for i.MX 6SL + LPDDR2 systems.
Technical Context
The MC33PF3000A5ESR2 implements SMARTMOS technology and uses OTP memory to store startup sequence, regulator voltages, and mode settings-eliminating external configuration components. Its SW1A/SW1B can operate independently or combine into a single 2.75 A buck channel, while SW2 supports dual output ranges (1.50–1.85 V or 2.50–3.30 V) for flexible core/I/O rail assignment.
It features programmable PWRON edge/level detection, STANDBY polarity inversion, RESETBMCU fault-mode enablement, and I²C-based runtime reconfiguration of functional registers (e.g., SW1AVOLT). The VREFDDR output tracks 0.5 × SW3_OUT with ±1% accuracy, and VSNVS operates as either an always-on 3.0 V LDO or bypass switch powered by VIN or coin cell.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR via external PFET); enables compatibility with Li-ion, USB, or higher-voltage industrial supplies |
| SW1A output | 0.7–1.425 V or 1.8/3.3 V, 1.0 A; supplies i.MX 6SL ARM core with DVS-capable dynamic scaling |
| SW1B output | 0.7–1.475 V, 1.75 A; configurable as independent rail or combined with SW1A for 2.75 A high-current core supply |
| VCC_SD output | 1.80–1.85 V or 2.85–3.30 V, 100 mA; dual-range LDO supporting SD card interface voltage selection via SD_VSEL pin |
| VREFDDR output | 0.5 × SW3_OUT (0.5–0.9 V), 10 mA; precision DDR memory reference with tracking accuracy critical for LPDDR2 timing compliance |
| I²C address | Programmable 0x08–0x0F (OTP-configurable); avoids bus conflicts in multi-PMIC or sensor-rich embedded designs |
| Startup sequence | OTP-programmable per-regulator slot (1–15 steps, 0.5/2.0 ms spacing); ensures safe, deterministic power-up of i.MX 6SL + LPDDR2 subsystems |
Pinout & Package
MC33PF3000A5ESR2 uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), optimized for thermal dissipation and automated optical inspection. The exposed pad (EP) must be connected to ground planes via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INTB | Open-drain interrupt output | Asserts low on fault (OCP, UVLO, thermal); requires external pull-up; used for system-level fault monitoring |
| 2 SD_VSEL | Digital input (VDDIO-referenced) | Selects VCC_SD output range: HIGH = 1.80–1.85 V, LOW = 2.85–3.30 V; defaults HIGH if VDDIO absent |
| 3 RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after last regulator enables; configurable for fault-mode assertion on persistent error (>1.8 ms) |
| 4 STANDBY | Digital input (active-high/low OTP-selectable) | Enters/exits Standby mode; requires coin cell for reliable operation at VIN ≤ 2.85 V |
| 45 SDA / 46 SCL | I²C bidirectional data/clock | Supports OTP programming and runtime register access; pull-ups to VDDIO (1.7–3.6 V); 400 kHz fast-mode compatible |
| 48 PWRON | Power-on control input | Configurable edge/level trigger; includes hardware debounce (31.25–750 ms falling-edge); initiates startup sequence |
Key Features
| Feature | Design Value |
|---|---|
| OTP-programmable power tree | Stores startup sequence, regulator voltages, I²C address, PWRON/RESETBMCU modes - eliminates external resistors, jumpers, or firmware init overhead |
| SW1A/SW1B configuration flexibility | Single 2.75 A channel or independent 1.0 A + 1.75 A rails - adapts to i.MX 6SL core power profiles without PCB change |
| VREFDDR tracking accuracy | 0.5 × SW3_OUT with ±1% tolerance - meets LPDDR2 VREF specification for stable memory interface timing |
| VSNVS dual-mode operation | 3.0 V always-on LDO or bypass switch - maintains SNVS domain during main power loss using coin cell backup |
| Dynamic voltage scaling (DVS) | Programmable soft-start ramp (25 mV/2 µs or 25 mV/4 µs) and PWM/PPM/APS modes - reduces inrush current and improves transient response |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A6ESR2 | OTP-configured for i.MX 6UL + LPDDR2 (not i.MX 6SL); identical pinout, package, and regulator specs | Targets i.MX 6UL-based designs; incompatible startup sequence and voltage settings for i.MX 6SL + LPDDR2 | Select only when migrating from i.MX 6SL to i.MX 6UL; requires full power tree validation |
| MC34PF3000A5ESR2 | Industrial-temp grade (−40 °C to +105 °C); same OTP config (A5), identical electrical specs and pinout | Rated for extended-temperature industrial environments; not qualified for automotive or consumer thermal profiles | Choose for harsh-environment deployments where MC33PF3000A5ESR2's −40 °C to +85 °C rating is insufficient |
Compared with MC33PF3000A5ESR2, MC33PF3000A6ESR2 serves a different processor variant (i.MX 6UL vs. i.MX 6SL) and requires revalidation of OTP settings, while MC34PF3000A5ESR2 offers identical functionality with extended temperature capability - making it a drop-in replacement only for thermal-critical industrial use cases.

FAQ
What is the operating temperature range for MC33PF3000A5ESR2?
MC33PF3000A5ESR2 is rated for −40 °C to +85 °C ambient operation, qualifying it for consumer and industrial applications but not automotive-grade environments. This range aligns with its intended use with i.MX 6SL processors in handheld and edge computing devices where thermal management is controlled via PCB layout and enclosure design. The device incorporates thermal shutdown protection to safeguard against sustained overtemperature conditions.
How does the OTP programming differ between MC33PF3000A5ESR2 and other PF3000 variants?
MC33PF3000A5ESR2 is pre-programmed with OTP settings optimized for i.MX 6SL processors paired with LPDDR2 memory - including startup sequence order, SW1A/SW1B configuration, and VREFDDR tracking ratio. Other variants (e.g., A3ESR2 for i.MX 6SX+DDR3L) contain distinct OTP maps; reprogramming is not supported post-manufacture, and mixing OTP configurations risks incorrect power sequencing or rail voltage errors.
Can MC33PF3000A5ESR2 support both DDR3L and LPDDR2 memory interfaces?
No - MC33PF3000A5ESR2 is specifically configured for LPDDR2 memory via its OTP-mapped VREFDDR generation (0.5 × SW3_OUT) and startup timing. DDR3L support requires different VREFDDR voltage (0.9 V fixed or 0.75 V tracking) and sequencing, implemented in variants like MC32PF3000A1ESR2 (i.MX 7 + DDR3L). Using MC33PF3000A5ESR2 with DDR3L violates memory interface specifications and may cause initialization failure.
What is the role of the VPWR pin on MC33PF3000A5ESR2?
The VPWR pin on MC33PF3000A5ESR2 enables operation with input voltages up to 5.5 V by interfacing with an external P-channel MOSFET to form a front-end LDO. When VPWR is used, VIN is derived from the PFET drain, limiting internal regulator input to ≤4.5 V. This protects the PMIC in systems powered by USB PD, 5 V wall adapters, or industrial supplies exceeding the 4.5 V VIN absolute maximum rating.
Is MC33PF3000A5ESR2 pin-compatible with MC32PF3000A5ESR2?
Yes - MC33PF3000A5ESR2 and MC32PF3000A5ESR2 share identical 48-pin QFN packaging, pinout, and electrical characteristics. The prefix difference (MC32 vs. MC33) denotes temperature grade: MC32 is automotive (−40 °C to +105 °C), while MC33 is consumer/industrial (−40 °C to +85 °C). Both use the same A5 OTP configuration for i.MX 6SL + LPDDR2, making them functionally interchangeable where temperature requirements permit.
