Product details
Overview
MC33GD3000EPR2 from NXP Semiconductors is a three-phase FET predriver IC for automotive motor control, integrating six independent gate drivers (three high-side and three low-side), SPI-configurable dead time, 15 V regulated VLS supply, 1.0–2.5 A peak gate drive strength, and AEC-Q100 Grade 1 qualification. It interfaces directly with MCUs in electric power steering and belt starter generator systems.
For engineers reviewing the MC33GD3000EPR2 datasheet, MC33GD3000EPR2 pinout, MC33GD3000EPR2 application, or MC33GD3000EPR2 equivalent, key selection considerations include bootstrap-capable high-side drive up to 75 V, integrated current-sensing amplifier with programmable overcurrent threshold, 3.0–5.0 V logic compatibility, and HVQFN56 thermal-enhanced packaging for high-power density motor control designs.
Technical Context
The MC33GD3000EPR2 implements SMARTMOS technology with independent high- and low-side driver stages per phase, each featuring low-impedance gate outputs (≤1 Ω typical) and built-in protection against reverse charge injection from external FETs' CGD/CGS. Its internal 15 V VLS regulator powers all gate drives and bootstrap circuits.
Functional safety is supported via dual enable inputs (EN1/EN2 AND-gated), asynchronous reset (RST_B), fault-interrupt output (INT), and configurable SPI masking of overcurrent, desaturation, and thermal events. The device operates across 6.0–60 V VPWR and is fully specified from 8.0–40 V for 12 V and 24 V automotive systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ6532-AEC1 | Integrated 65 V half-bridge drivers with embedded current sense; no SPI configuration; fixed dead time | Lacks programmable dead time and phase comparator outputs; suited for simpler BLDC commutation only | Choose MPQ6532-AEC1 when SPI configurability and PHASEx feedback are unnecessary and board space is constrained |
| UCC27211A-Q1 | Dual high-/low-side driver (not three-phase); 4 A peak drive; no integrated regulators or current sense | Requires external bootstrap, VDD, and current sensing circuitry; needs three ICs for full three-phase implementation | Choose UCC27211A-Q1 when maximum drive strength (4 A) is required per channel and system-level integration is handled externally |

FAQ
What is the maximum bootstrap voltage supported by the MC33GD3000EPR2?
The MC33GD3000EPR2 supports a bootstrap voltage (VBOOT) of 22 V to 32 V when VSUP = 14 V, with absolute maximum rating of 75 V on high-side gate outputs. This allows robust high-side FET turn-on under cold-crank and load-dump conditions common in automotive 12 V systems. The internal clamp limits voltage across the bootstrap capacitor to approximately 15 V relative to the high-side source.
Does the MC33GD3000EPR2 require external bootstrap diodes?
No, the MC33GD3000EPR2 does not require external bootstrap diodes. Its internal trickle charge pump and integrated high-side driver architecture eliminate the need for discrete bootstrap diodes. The device uses external bootstrap capacitors (e.g., 10×–20× FET gate capacitance) connected between PA_BOOT/VSUP, PB_BOOT/VSUP, and PC_BOOT/VSUP - with internal circuitry managing charge replenishment during continuous conduction.
How is overcurrent protection implemented in the MC33GD3000EPR2?
The MC33GD3000EPR2 implements overcurrent protection using an integrated current-sensing amplifier with differential inputs (AMP_P/AMP_N) and a dedicated comparator. The OC_TH pin sets the overcurrent threshold voltage, and the OC_OUT pin provides a totem-pole logic output indicating fault condition. Faults can be masked or cleared via SPI commands, and the INT pin asserts a hardware interrupt for immediate MCU response.
Can the MC33GD3000EPR2 drive SiC or GaN FETs?
Yes, the MC33GD3000EPR2 can drive SiC and GaN FETs in three-phase configurations. Its 2.5 A peak gate drive strength, <1 Ω output impedance, and 75 V absolute maximum gate-source voltage rating accommodate the higher gate charge and faster switching requirements of wide-bandgap devices. Designers must ensure proper PCB layout for gate loop inductance and verify bootstrap operation under high dV/dt conditions.
What is the purpose of the PHASEA, PHASEB, and PHASEC pins on the MC33GD3000EPR2?
The PHASEA, PHASEB, and PHASEC pins on the MC33GD3000EPR2 are totem-pole comparator outputs that indicate whether the respective high-side FET source voltage is below 50 % of VSUP. These signals provide real-time feedback on high-side conduction state and are used for commutation timing, desaturation detection, and closed-loop control - enabling advanced motor control algorithms like six-step or field-oriented control without external comparators.
