Product details

Overview

MPQ6615GQKTE-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified H-bridge DC motor driver IC with four integrated N-channel MOSFETs (11 mΩ R_DS(ON) at T_J = 25°C), 4.75–40 V input voltage range, 8 A continuous output current capability, and integrated bidirectional current-sense amplifiers. It delivers precise control for automotive brushed DC motors in seat actuators, door latches, and window regulators.

For engineers reviewing the MPQ6615GQKTE-AEC1-P datasheet, MPQ6615GQKTE-AEC1-P pinout, MPQ6615GQKTE-AEC1-P application, or MPQ6615GQKTE-AEC1-P equivalent, key selection considerations include its 100% duty-cycle support via internal charge pump, latch-off/retry OCP mode selection via OCMD pin, dual-phase current sensing (SOA/SOB), and wettable-flank TQFN-26 package for automated optical inspection.

Technical Context

The MPQ6615GQKTE-AEC1-P implements a fully integrated H-bridge with independent gate drivers, internal charge pump (2 MHz switching, V_VCP = V_IN + 5 V), and low-side gate regulator (VG ≈ 5.5 V). Its three configurable input modes (selected by INM[1:0]) support EN/PWM, ENBL/DIR/BRK, or INH/INL control schemes - enabling flexible microcontroller interface without external logic.

Protection architecture includes UVLO (4.4 V rising threshold, 480 mV hysteresis), OVP (48 V rising threshold), thermal shutdown (150°C, 25°C hysteresis), and dual-path over-current detection (HS/LS thresholds at 25 A typ, 0.4 µs deglitch). Current sensing uses matched internal amplifiers with phase-specific CS ratios (1/11000 A/A typ for Phase A, 1/10500 A/A typ for Phase B) and ±20 µA offset.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar H-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8876QPWPRQ1	Lower 4.5–37 V input range; 6.5 A continuous current; no integrated current-sense outputs (requires external shunt + amplifier).	Targeted at cost-sensitive body electronics where current feedback is not required for closed-loop control.	Select when system-level current sensing is handled externally and 8 A drive capability is not mandatory.
BD6212FJ-E2	Higher 6–36 V range; 3.5 A continuous current; only single-phase output; no AEC-Q100 qualification.	Suitable for non-automotive industrial actuators or consumer appliances with less stringent reliability requirements.	Choose only for non-automotive designs lacking AEC-Q100 mandate and requiring lower current capability.

Compared with DRV8876QPWPRQ1 and BD6212FJ-E2, the MPQ6615GQKTE-AEC1-P uniquely combines AEC-Q100 Grade 1 qualification, integrated dual-phase current sensing, 8 A drive, and 100% duty-cycle support - making it the only option for automotive applications demanding both functional safety and precision motor control in a single chip.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The MPQ6615GQKTE-AEC1-P has a maximum junction temperature of +125°C for continuous operation under AEC-Q100 Grade 1 conditions. Thermal shutdown activates at +150°C with 25°C hysteresis, ensuring safe recovery before resuming drive. PCB layout must maintain θ_JA ≤ 21.4°C/W on a 4-layer board to sustain 8 A output at 125°C ambient.

How does the OCMD pin affect fault recovery behavior?

The OCMD pin selects over-current protection mode: tied to GND enables latch-off (device remains disabled until VIN drops below UVLO threshold); left open or pulled high enables auto-retry (outputs disable for 2 ms then re-enable). This allows system-level choice between fail-safe shutdown and self-recovering operation based on motor fault tolerance requirements.

Can the MPQ6615GQKTE-AEC1-P drive a single motor in H-bridge mode using only one phase?

Yes - the device supports single-motor operation using either Phase A (SA/SOA) or Phase B (SB/SOB) independently. When configured in ENBL/DIR mode (INM[1:0] = 01), ENBL enables the full bridge while DIR controls direction, and BRK/BMOD provides active braking. Both phases share identical electrical specs and protection features.

What external capacitors are mandatory for stable operation?

Three capacitor types are mandatory: (1) 4.7–10 µF X7R ceramic between VG and GND; (2) 1 µF/10 V X7R between VCP and VIN; (3) 100 nF X7R between CP1 and CP2. All must be placed within 2 mm of respective pins per MPS layout guidelines to prevent charge pump instability and gate drive collapse.

Is the current-sense output polarity reversible for bidirectional motor current measurement?

Yes - SOA and SOB are true bidirectional current-sense outputs: they source current when motor current flows from SA/SB to PGND (forward direction) and sink current when current flows from PGND to SA/SB (reverse direction). With proper R_REF/V_REF termination, V_SOx swings above and below V_REF, enabling full four-quadrant torque control.

Does the device support PWM frequencies beyond 20 kHz?

Yes - the MPQ6615GQKTE-AEC1-P supports PWM frequencies up to 100 kHz, though operating current increases with frequency (e.g., 60 mA at 100 kHz, VIN = 24 V, TA = 25°C). For noise-sensitive applications like power windows, 20–25 kHz is recommended to avoid audible whine while maintaining efficiency.

How is thermal performance affected by PCB copper area and via placement?

Thermal resistance θ_JA drops from 21.4°C/W (baseline 4-layer) to ≤15°C/W with ≥400 mm² of 2-oz copper on top/bottom layers plus ≥12 thermal vias (0.3 mm diameter) under the exposed pad. Insufficient copper or vias causes premature thermal shutdown at <6 A continuous load, even at 25°C ambient.
