Product details

Overview

MPQ6610GJ-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified half-bridge power driver IC designed for automotive brushed DC motor, solenoid, and relay control. It operates from 4V to 45V (TSOT23 package), delivers up to 3A output current, integrates cycle-by-cycle current regulation without external shunt resistors, and features open-load detection, OCP, UVLO, thermal shutdown, and fault-indication via open-drain nFAULT.

For engineers reviewing the MPQ6610GJ-AEC1-Z datasheet, MPQ6610GJ-AEC1-Z pinout, MPQ6610GJ-AEC1-Z application, or MPQ6610GJ-AEC1-Z equivalent, key selection criteria include its 45V max VIN rating in TSOT23-8, 100mΩ/120mΩ HS/LS R_DS(on), 1.5V current-trip threshold at ISET, AEC-Q100 qualification, and bootstrap-based high-side gate drive architecture.

Technical Context

The MPQ6610GJ-AEC1-Z implements a constant-off-time (COT) PWM current regulation loop that triggers on ISET reaching 1.4–1.6V, with 1µs blanking time to suppress turn-on current spikes. Its internal bootstrap capacitor charging circuit sustains high-side N-MOSFET gate drive during extended high-state periods.

Logic interface supports 2.5V/3.3V/5V inputs with internal pull-downs on EN and IN; fault reporting uses open-drain nFAULT asserting low for OCP, OTP, and open-load events-but not for regulated current-limit trips. Protection thresholds are temperature-compensated: UVLO rising at 4.1V ±300mV, OVP at 55–65V, thermal shutdown at 165°C with 15°C hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	4V to 45V - Valid for TSOT23-8 package; enables direct battery-supply operation in 12V/24V automotive systems.
Max Output Current	±3A - Continuous load current capability under thermal limits; derates with ambient temperature and PCB copper area.
HS/LS R_DS(on)	100mΩ / 120mΩ @ 25°C - Low conduction loss enabling >90% efficiency at 2A/24V with minimal heatsinking.
Current Trip Threshold	1.5V at ISET pin - Sets precise overcurrent limit via external resistor; e.g., 10kΩ yields 1.5A trip point.
Fault Reporting	Open-drain nFAULT - Active-low signal indicating OCP, OTP, or open-load; requires external pull-up for system-level fault handling.
AEC-Q100 Grade	Grade 1 (−40°C to +125°C T_J) - Qualified for engine bay and transmission control applications requiring automotive reliability.
Thermal Resistance	θ_JA = 100°C/W - Dictates maximum power dissipation of 1.25W at 25°C ambient; mandates careful layout for sustained 3A operation.

Pinout & Package

MPQ6610GJ-AEC1-Z is housed in an 8-pin TSOT23 package (JEDEC MO-193BA), optimized for space-constrained automotive modules. Pin spacing is 0.5mm; conformal coating recommended for >45V operation.

Pin/Terminal	Circuit Role	Design Meaning
1 (EN)	H-bridge enable input	Internal 530kΩ pull-down; logic-high (>2V) required to activate driver; disables all outputs when low.
2 (IN)	H-bridge control input	Determines output state per truth table: EN=high + IN=high → OUT=high; IN=low → OUT=low.
3 (ISET)	Current-sense scaling node	Sources 100µA/A of load current; voltage at pin sets current limit (1.5V threshold); connects to ground via resistor.
4 (nFAULT)	Fault status indicator	Open-drain output pulled low during OCP, OTP, or open-load; requires external pull-up for microcontroller interrupt.
5 (GND)	Power and signal reference	System ground return path for all internal circuits; must be low-impedance connection to minimize noise coupling.
6 (OUT)	Half-bridge output terminal	Switching node between HS and LS MOSFETs; connects directly to motor/solenoid load; requires low-inductance routing.
7 (VIN)	Main supply input	4–45V input; decoupled with ≥100nF ceramic capacitor close to pin; powers internal logic and gate drivers.
8 (BST)	Bootstrap capacitor connection	Connects 100nF capacitor to OUT; supplies gate drive voltage for high-side N-MOSFET; critical for shoot-through prevention.

Key Features

Feature	Design Value
Integrated current sensing	Eliminates need for external shunt resistor; provides analog ISET voltage proportional to load current (100µA/A).
Cycle-by-cycle regulation	Uses COT PWM with 16.5µs off-time after trip; maintains precise current control without external compensation.
Automotive-grade protection	Includes AEC-Q100-compliant UVLO (4.1V), OVP (55–65V), OTP (165°C), and open-load detection (V_OUT ≈ V_IN/2).
Logic-level compatibility	Accepts 2.5V/3.3V/5V inputs on EN and IN; internal pull-downs simplify microcontroller interfacing without external biasing.
Thermally enhanced TSOT23	θ_JA = 100°C/W enables 3A operation with minimal PCB copper; suitable for compact ECU and body-control modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPQ6610GS-AEC1-Z	SOIC-8 package; 55V max VIN; θ_JA = 96°C/W; higher thermal margin and voltage headroom.	Suitable for under-hood applications requiring full 55V operation or higher power dissipation.	Select when board space allows SOIC-8 and system voltage exceeds 45V or thermal load exceeds TSOT23 limits.
DRV8876QPWRQ1	Texas Instruments part; integrated current sense amplifier (not just ISET voltage); 45V rating; SPI interface for diagnostics.	Offers digital fault reporting and programmable parameters, but larger QFN package and higher BOM cost.	Choose when advanced telemetry (e.g., real-time current readback) or multi-device daisy-chaining is required.

Compared with MPQ6610GS-AEC1-Z, the MPQ6610GJ-AEC1-Z trades voltage headroom and thermal margin for ultra-compact size-ideal for space-limited modules where 45V suffices. Against DRV8876QPWRQ1, it offers simpler analog interface and lower cost, but lacks digital configurability and integrated current-sense amplification.

FAQ

What is the maximum allowable input voltage for MPQ6610GJ-AEC1-Z?

The absolute maximum VIN is +65V, but the recommended operating range is 4V to 45V due to TSOT23-8 package limitations. Exceeding 45V risks reliability without conformal coating or encapsulation, as specified in the datasheet's package note.

How does the ISET pin configure current limiting?

The ISET pin sources 100µA per ampere of load current. A resistor from ISET to GND sets the trip voltage: when ISET reaches 1.4–1.6V (typ. 1.5V), cycle-by-cycle regulation activates. For example, a 10kΩ resistor yields a 1.5A limit.

Does nFAULT assert during current-regulation events?

No. The nFAULT pin remains high during normal cycle-by-cycle current regulation. It only pulls low for fault conditions including over-current protection (OCP), over-temperature protection (OTP), and open-load detection-not for regulated current limiting.

What is the purpose of the BST pin and required external component?

The BST pin connects to a 100nF ceramic capacitor between BST and OUT. This bootstrap network generates the gate drive voltage for the internal high-side N-MOSFET, enabling efficient high-side switching without a dedicated floating supply.

Can MPQ6610GJ-AEC1-Z drive inductive loads without external flyback diodes?

Yes. The device integrates body diodes in its internal HS and LS MOSFETs, which provide freewheeling paths for inductive kickback. No external diodes are required for standard brushed DC motor or solenoid operation.

Is the TSOT23-8 package lead-free and RoHS compliant?

Yes. MPQ6610GJ-AEC1-Z is lead-free, halogen-free, and fully RoHS compliant per MPS green status documentation. The top marking "AVR" and year code confirm manufacturing traceability per AEC-Q100 requirements.

How does open-load detection function without external components?

When EN = 0, internal circuitry weakly pulls OUT to VIN/2. If no load is connected, V_OUT settles near VIN/2, triggering open-load detection and pulling nFAULT low. Load presence pulls V_OUT toward GND or VIN, preventing false faults.
