Product details

Overview

MPQ6610GJ-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified half-bridge power driver for automotive and industrial loads, delivering up to 3A output current with integrated current sensing, cycle-by-cycle regulation, and fault reporting. It operates from 4V to 45V (TSOT23 package), features 100mΩ high-side and 120mΩ low-side R_DS(on), and supports brushed DC motor, solenoid, and relay control in engine management and body electronics.

For engineers reviewing the MPQ6610GJ-AEC1-P datasheet, MPQ6610GJ-AEC1-P pinout, MPQ6610GJ-AEC1-P application, or MPQ6610GJ-AEC1-P equivalent, key selection criteria include its AEC-Q100 qualification, internal current-sense scaling (1.5V trip at ISET), open-drain nFAULT reporting, and TSOT23-8 thermal limits (1.25W @ 25°C).

Technical Context

The MPQ6610GJ-AEC1-P integrates dual N-channel MOSFETs with bootstrap gate drive and a trickle charge pump for high-side switching. Its constant-off-time (COT) PWM current regulation uses ISET pin voltage feedback (1.4–1.6V trip threshold) and includes 1µs blanking time to suppress turn-on current spikes.

Protection logic independently monitors over-current (3A sink/source OCP), open-load (via OUT voltage at VIN/2), UVLO (4.1V rising), OVP (55–65V), and thermal shutdown (165°C). The nFAULT pin reports all faults except current-limit trips, and EN/IN logic enables Hi-Z, high, or low output states per Table 1.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4V to 45V - Validated for TSOT23-8 package; exceeds 45V requires conformal coating per datasheet note.
Max Output Current	±3A - Continuous rating dependent on PCB layout, ambient temperature, and thermal derating per θ_JA = 100°C/W.
R_DS(on) (HS/LS)	100mΩ / 120mΩ - Measured at VIN = 24V, I_OUT = 1A, T_J = 25°C; increases to 200mΩ/256mΩ at 125°C.
Current Trip Threshold	1.5V at ISET pin - Sets 3A limit with 5kΩ resistor (1.5V / 5kΩ = 300µA → 3A × 100µA/A); scalable via external resistor.
Fault Reporting	Open-drain nFAULT - Active-low signal for OCP, OTP, and open-load; requires external pull-up; not asserted during current regulation.
AEC-Q100 Grade	Grade 1 (−40°C to +125°C T_J) - Qualified per stress test requirements for automotive powertrain and chassis applications.
Thermal Dissipation	1.25W max (TSOT23-8) - Derates linearly above 25°C ambient; junction-to-ambient θ_JA = 100°C/W on 4-layer PCB.

Pinout & Package

MPQ6610GJ-AEC1-P is housed in an 8-pin TSOT23 package (JEDEC MO-193BA), optimized for space-constrained automotive modules. Pin spacing is 0.5mm; recommended land pattern and coplanarity ≤0.10mm ensure reliable reflow soldering.

Pin	Circuit Role	Design Meaning
1	EN	Enable input with internal 530kΩ pull-down; drives H-bridge into Hi-Z when low; logic-compatible with 2.5V/3.3V/5V systems.
2	IN	Control input with internal pull-down; sets output state (high/low/Hi-Z) per truth table; independent of EN status.
3	ISET	Current configuration node; outputs voltage proportional to load current (100µA/A); sets trip threshold via external resistor to GND.
4	nFAULT	Open-drain fault indicator; sinks current during OCP, OTP, or open-load; requires external pull-up for system-level interrupt signaling.
5	GND	System ground reference for all internal circuits and current-sense amplifier; must be low-impedance connection to minimize noise.
6	OUT	Half-bridge output terminal; connects to motor/solenoid load; voltage swings between GND and VIN depending on FET state.
7	VIN	Main power input (4–45V); requires ≥100nF ceramic decoupling capacitor to GND near pin for stable operation.
8	BST	Bootstrap capacitor connection (100nF to OUT); supplies gate drive voltage for high-side N-MOSFET; enables efficient 100% duty-cycle capability.

Key Features

Feature	Design Value
Cycle-by-cycle current regulation	Uses internal COT PWM with 16.5µs off-time after trip; eliminates need for external shunt resistor while maintaining ±3A accuracy across temperature.
No auxiliary supply required	Self-powered gate drive architecture with integrated trickle charge pump and bootstrap capacitor support reduces BOM count and layout complexity.
Logic-level input compatibility	Accepts 2.5V/3.3V/5V logic signals directly on IN/EN pins without level-shifting, simplifying MCU interface in 12V/24V automotive systems.
Integrated open-load detection	Monitors OUT voltage during Hi-Z state (EN = 0); asserts nFAULT if V_OUT ≈ VIN/2, enabling early failure detection in solenoid and relay drivers.
Thermally enhanced TSOT23-8	θ_JA = 100°C/W on 4-layer board; supports 1.25W dissipation at 25°C ambient; validated for under-hood environments with proper copper pour.

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-P	SOIC-8 package with higher 55V VIN rating, 1.302W power dissipation, and θ_JA = 96°C/W - no conformal coating needed for 45–55V operation.	Preferred for under-hood applications requiring >45V operation or higher thermal margin; larger footprint but easier thermal management.	Select GS variant when board space allows and system voltage exceeds 45V or ambient temperature exceeds 85°C.
TLE9201SG	Infineon's AEC-Q100 Grade 0 half-bridge with integrated LIN transceiver, 40V max VIN, and SPI diagnostic interface - lacks internal current-sense scaling.	Used in LIN-connected actuators where bus communication is required; requires external sense resistor and microcontroller-based current interpretation.	Choose TLE9201SG only when LIN protocol integration is mandatory and added MCU firmware overhead is acceptable.

Compared with MPQ6610GJ-AEC1-P, the GS variant offers higher voltage headroom and thermal capacity in SOIC-8, while the TLE9201SG trades analog current reporting for digital diagnostics and communication - making the MPQ6610GJ-AEC1-P optimal for cost-sensitive, analog-feedback automotive actuators needing compact size and self-contained regulation.

FAQ

What is the maximum continuous operating voltage for MPQ6610GJ-AEC1-P?

The MPQ6610GJ-AEC1-P is rated for 4V to 45V continuous input voltage in the TSOT23-8 package, as confirmed by absolute maximum ratings (VIN ≤ +65V) and recommended operating conditions. Operation above 45V requires conformal coating or encapsulation per datasheet Note on page 1.

How does the ISET pin enable current measurement without an external shunt?

The ISET pin sources current proportional to load current (100µA/A) and develops a voltage across an external resistor to ground. With a 10kΩ resistor, 1V appears per ampere of load current, enabling analog current monitoring and 1.5V trip threshold for 3A regulation - eliminating the need for a separate shunt resistor and amplifier.

Does nFAULT assert during normal current-limit regulation events?

No - nFAULT is not driven low during cycle-by-cycle current regulation or current-limit trips. It only activates for hard faults: over-current protection (OCP), over-temperature protection (OTP), or open-load detection. This separation allows systems to distinguish between transient overload and permanent failure.

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, forming a bootstrap circuit that generates the gate drive voltage for the high-side N-MOSFET. This enables efficient high-side switching without a dedicated floating supply, supporting 100% duty-cycle operation when paired with the internal trickle charge pump.

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

Yes - the device integrates body diodes in both high-side and low-side MOSFETs (VF = 1.1V typical), which provide freewheeling paths for inductive kickback. No external flyback diodes are required for standard brushed DC motor or solenoid loads, reducing bill-of-materials and PCB area.

What thermal derating applies above 25°C ambient temperature?

Power dissipation must be reduced linearly using θ_JA = 100°C/W: PD_MAX = (150°C − T_A) / 100. At 85°C ambient, maximum continuous power drops to 0.65W. Layout with ≥2 cm² of 2-oz copper connected to GND and OUT pins is recommended to maintain reliability.

Is the EN pin internally pulled down, and what is its leakage behavior?

Yes - EN has an internal 530kΩ pull-down resistor, ensuring the H-bridge remains disabled during power-up or MCU reset. Input leakage is ±4 µA at logic low and ±14 µA at logic high, allowing direct connection to microcontroller GPIO without external biasing.
