Product details
Overview
MPQ6532GVE-AEC1-Z from Monolithic Power Systems is a three-phase BLDC motor pre-driver IC designed to control six external N-channel MOSFETs in half-bridge configurations across 5V–60V input rails. It integrates 120° Hall-sensor commutation logic, charge-pump–boosted gate drive (VREG = 9.5–13V), and bootstrap high-side drivers with trickle-charge support for 100% duty cycle operation. Used in automotive HVAC blowers, electric power steering assist modules, and engine cooling fans.
For engineers reviewing the MPQ6532GVE-AEC1-Z datasheet, MPQ6532GVE-AEC1-Z pinout, MPQ6532GVE-AEC1-Z application, or MPQ6532GVE-AEC1-Z equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, configurable dead-time (90 ns to 5.7 µs), integrated OCP via LSS current sensing, VDS-based short-circuit protection, and thermal shutdown at 190°C.
Technical Context
The MPQ6532GVE-AEC1-Z implements a dedicated Hall-input–driven 120° commutation engine that sequences phase outputs based on HA/HB/HC transitions, with automatic low-side pulse insertion (tLS = 2 µs) before each commutation to recharge BST capacitors. Its gate drive architecture combines a regulated charge pump (fCP = 110 kHz) for VREG generation and per-phase bootstrap circuits with internal trickle-charge (≈5 µA) to sustain high-side drive under continuous conduction.
Safety logic includes dual over-current mechanisms: VDS monitoring (OC_REF threshold 0.8–2.62 V) for short-circuit detection with 3 µs deglitch, and LSS shunt-based OCP with fixed 70 µs off-time and 0.4–0.6 V trip threshold. Fault reporting is consolidated on open-drain nFAULT, latched until reset by nSLEEP or VIN UVLO recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 5V to 60V - supports 12V/24V/48V automotive battery systems with transient tolerance up to +62V. |
| VREG Output | 9.5V to 13V - regulated gate drive supply enabling robust N-MOSFET turn-on even at low VIN (e.g., cold-crank 5V). |
| Gate Drive Current | 0.8A source / 1A sink - sufficient for driving high-Qg automotive MOSFETs without external buffers. |
| Dead Time Range | 90 ns to 5.7 µs - adjustable via single RDT resistor to prevent shoot-through across all three phases. |
| OCP Threshold | 0.4V to 0.6V at LSS - sets motor stall current limit using external sense resistor; fixed 70 µs off-time limits peak energy during fault. |
| Thermal Shutdown | 190°C with 30°C hysteresis - protects die during overload or poor heatsinking; auto-recovery after cooldown. |
| UVLO Threshold | 3.2V to 5V rising with 200 mV hysteresis - ensures clean start-up and prevents erratic operation during brownout. |
Pinout & Package
MPQ6532GVE-AEC1-Z is housed in a thermally enhanced wettable-flank QFN-28 (4mm × 5mm) package with exposed GND pad for PCB-level heat dissipation and solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (1) | Main power input | Bypassed to GND; supplies charge pump, logic, and gate drivers; must withstand 62V transients. |
| CPA/CPB (2–3) | Charge pump flying capacitor terminals | Connect 470nF X7R ceramic; forms doubler stage generating VREG from VIN. |
| VREG (4) | Regulated gate drive supply output | Provides 9.5–13V to LS drivers and BST charging path; requires 10µF ceramic to GND. |
| BSTA–BSTC (5,9,13) | Bootstrap supply inputs per phase | Each connects to respective SHA/SHB/SHC via ceramic capacitor; sustains HS drive during 100% duty cycle via trickle-charge. |
| GHA–GLC (7–8,11–12,15–16) | HS/LS gate drive outputs | Directly drive MOSFET gates; 0.8A source / 1A sink capability enables fast switching of automotive-grade FETs. |
| HA/HB/HC (18–20) | Hall sensor inputs | Internal 880kΩ pull-down; decode rotor position for 120° commutation without external logic. |
| nBRAKE (21) | Active-low brake control | Pulls all LS-FETs high to short motor phases and dissipate kinetic energy; internal pull-down ensures safe default state. |
| nFAULT (24) | Open-drain fault indicator | Asserts low on OCP, SCP, UVLO, or thermal fault; requires external pull-up for system-level interrupt signaling. |
Key Features
| Feature | Design Value |
|---|---|
| 120° Hall-commutation engine | Eliminates need for external microcontroller or FPGA in basic BLDC control; reduces BOM and firmware complexity. |
| Trickle-charge BST circuit | Maintains high-side gate voltage during 100% duty cycle - critical for torque-holding applications like parking brakes. |
| Configurable dead-time (RDT) | Single-resistor adjustment (90 ns–5.7 µs) ensures shoot-through immunity across varying MOSFET gate charge and layout parasitics. |
| Dual over-current protection | VDS sensing (3 µs response) + LSS shunt sensing (70 µs off-time) provide layered fault coverage for both short-circuit and stall conditions. |
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +150°C junction operation - meets automotive powertrain and chassis module reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC pre-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8305-Q1 | Integrated current-sense amplifiers; no external LSS shunt required; SPI interface for configuration. | Requires MCU for commutation logic; not Hall-input autonomous. | Choose when system already uses MCU-based field-oriented control (FOC) and needs analog current feedback. |
| STSPIN32F0B | Embedded 32-bit ARM Cortex-M0; integrates gate drivers, op-amps, and ADC; no external Hall decoding needed. | Higher integration but larger footprint and firmware dependency; not pin-compatible. | Prefer for cost-sensitive designs where MCU consolidation offsets BOM increase and simplifies software stack. |
Compared with DRV8305-Q1 and STSPIN32F0B, MPQ6532GVE-AEC1-Z delivers autonomous Hall-commutated drive with minimal external components and lowest system-level design effort - ideal for deterministic, safety-critical automotive actuators where MCU resources are constrained or unavailable.

FAQ
What is the purpose of the trickle-charge circuit in MPQ6532GVE-AEC1-Z?
The trickle-charge circuit continuously supplies ≈5 µA to each bootstrap capacitor (BSTA/BSTB/BSTC) to maintain high-side gate drive voltage during 100% duty cycle operation. This prevents HS-FET turn-off in torque-hold or static-position applications - a critical requirement for automotive actuators like parking brakes and active grille shutters.
How does MPQ6532GVE-AEC1-Z implement short-circuit protection?
It uses VDS sensing on each MOSFET: if drain-to-source voltage exceeds the OC_REF reference (0.8–2.62 V), a short is detected. The 3 µs deglitch filter rejects switching noise, and the device immediately disables all gate outputs while pulling nFAULT low. Recovery requires nSLEEP toggle or VIN UVLO reset - no automatic retry.
Can MPQ6532GVE-AEC1-Z operate without Hall sensors?
No - the MPQ6532GVE-AEC1-Z relies exclusively on HA/HB/HC Hall inputs for commutation timing and phase sequencing. It lacks sensorless BEMF detection circuitry or external PWM commutation mode. For sensorless operation, an alternative driver such as MPQ6522 or external MCU control is required.
What is the minimum recommended BST capacitor value for MPQ6532GVE-AEC1-Z?
The minimum BST capacitance is calculated as CBOOT > 8 × QG (nF), where QG is the total gate charge (nC) of the driven MOSFET. For typical automotive N-FETs with QG = 50 nC, CBOOT > 400 nF is required. A 470 nF X7R ceramic capacitor rated ≥25 V is recommended; values >1 µF may cause instability.
Does MPQ6532GVE-AEC1-Z support 100% duty cycle on all three phases simultaneously?
No - it supports 100% duty cycle only on individual high-side outputs (e.g., GHA high while GLA low), enabled by the trickle-charge circuit. Simultaneous 100% duty cycle across all three phases is physically impossible in a three-phase BLDC topology due to commutation requirements and shoot-through prevention constraints.
How is dead time adjusted, and what is its impact on efficiency?
Dead time is set by a single resistor (RDT) from DT pin to GND, ranging from 90 ns (RDT = GND) to 5.7 µs (RDT = 100 kΩ). Too little dead time risks shoot-through and FET failure; too much increases conduction losses and torque ripple. Optimal value balances switching safety and motor efficiency - typically 300–700 ns for 24V/50A systems.
Is MPQ6532GVE-AEC1-Z compatible with both N-channel and P-channel high-side MOSFETs?
It is designed exclusively for N-channel high-side MOSFETs driven via bootstrap configuration. P-channel high-side use is unsupported - no internal level-shifting or charge-pump architecture exists for P-FET gate drive. External high-side drivers would be required for P-channel implementation.
