Product details

Overview

MPQ5069GQV-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 automotive hot-swap protection switch with integrated 7mΩ power MOSFET, adjustable current limit (5–15A), ±10% current monitor accuracy, and fast 200ns short-circuit response. It protects battery-fed systems in infotainment, clusters, and ADAS against input transients, output shorts, inrush, overcurrent, thermal overload, and damaged-MOSFET faults.

For engineers reviewing the MPQ5069GQV-AEC1-P datasheet, MPQ5069GQV-AEC1-P pinout, MPQ5069GQV-AEC1-P application, or MPQ5069GQV-AEC1-P equivalent, key selection criteria include its QFN-22 (3mm×5mm) AEC-Q100 package, programmable auto-retry/latch-off fault behavior via AUTO pin, IMON-based current monitoring, and VIN operating range of 6V–28V with load-dump tolerance to +39V.

Technical Context

The MPQ5069GQV-AEC1-P integrates a charge-pump-driven 7mΩ N-channel MOSFET and uses a sense-FET topology for current limiting, set by an external R_SET resistor. Its fault detection architecture includes dual-stage overcurrent protection: primary regulation at 10.5–14.5A (configurable) and secondary fast-turnoff at 25A with 200ns response.

It implements three independent protection timers: insertion delay (via TIMER pin capacitor), fault timeout (same CT), and auto-retry restart (0.5µA sink). PG and FLTB are open-drain status outputs with defined thresholds (PG asserts high only when V_FB > 0.6V, V_GS > 3V, and V_OUT > V_IN − 1V), while IMON delivers a voltage proportional to load current with 100mV/A scaling using a 10kΩ-to-ground resistor.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance (R_DS(ON))	7 mΩ typical - enables low conduction loss and minimal thermal rise at 12A continuous operation.
Current limit range	5 A to 15 A - set externally via R_SET; supports design margining above peak system loads.
Current monitor accuracy	±10% (6A–10A) - provides reliable real-time load current feedback for diagnostics and closed-loop control.
Short-circuit response time	200 ns - limits fault energy and prevents bus collapse during hard shorts in 12V/24V automotive systems.
Input voltage range	6 V to 28 V - covers cold-crank (6V), nominal (12V/24V), and ISO 16750-2 load-dump (up to +39V transient).
Thermal shutdown threshold	167 °C - protects die integrity under sustained overload; 28°C hysteresis enables safe recovery in auto-retry mode.
PG assertion condition	V_FB > 0.6V, V_GS > 3V, V_OUT > V_IN − 1V - ensures stable regulation before enabling downstream circuitry.
UVLO threshold	Rising: 4.15–5.5 V; Falling: 2.7–3.8 V - prevents erratic operation during brown-out or battery disconnect events.

Pinout & Package

MPQ5069GQV-AEC1-P is housed in a thermally enhanced QFN-22 (3mm × 5mm) package with exposed VIN pads (pins 21–22) and GND pad for optimal heat dissipation in automotive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 EN	Enable control input	Active-high logic; rising threshold 1.4–2.2V - enables/disables device and initiates insertion delay timer.
2 AUTO	Fault recovery mode select	Floating or >2.5V = auto-retry; grounded = latch-off - determines system-level fault handling strategy.
4 TIMER	Fault timing capacitor node	Charged by 40µA source; sets insertion delay, fault timeout, and restart period via external C_T.
5 ISET	Current limit programming	Resistor-to-GND sets ILIMIT per I_LIMIT = 0.6V × 20kΩ/R_SET - enables precise trip-point tuning.
6 SS	Soft-start ramp control	Capacitor-to-GND sets slew rate; floating yields ~1ms min soft-start - controls inrush into large output capacitance.
7 GND	Power and signal reference	Primary ground return for internal regulators, comparators, and current sensing - must be low-impedance.
8 IMON	Analog current monitor output	Voltage proportional to I_OUT; 100mV/A with 10kΩ-to-GND - feeds ADC or comparator for real-time load monitoring.
9 FLTB	Open-drain fault indicator	Pulled low on overcurrent, thermal shutdown, or damaged MOSFET - 20µs propagation delay for primary faults, ~8µs for 25A short.
10 PG	Open-drain power-good flag	Asserts high only after stable regulation is confirmed - used to enable downstream DC/DC converters or microcontrollers.
11 FB	Output voltage feedback	0.6V reference with 60mV hysteresis - sets PG transition point and supports optional output voltage monitoring.
12 PD	Output discharge control	Connects internal 500Ω pull-down to OUT when VIN < UVLO or EN near threshold - prevents floating rail during power removal.
13–20 OUT	Power output terminals	Eight parallel pins reduce trace resistance and improve current sharing - rated for 25A peak, 12.5A continuous.
21–22, Exposed Pad VIN	Main input power connection	High-current input path with thermal pad - requires multiple vias to inner ground/power planes for thermal management.

Key Features

Feature	Design Value
Integrated 7mΩ MOSFET with charge pump	Eliminates external gate driver and high-side FET; maintains full enhancement at low VIN (6V).
Configurable fault response (AUTO pin)	Enables system-level choice between hiccup-mode recovery (auto-retry) or manual reset (latch-off) without firmware change.
Dual-stage overcurrent protection	20µs regulated current limit + 200ns 25A fast turn-off - balances precision regulation with catastrophic fault containment.
IMON current monitor with ±10% accuracy	Provides analog diagnostic signal for ECU integration, eliminating need for external shunt and amplifier in many designs.
PG and FLTB with defined assertion conditions	Enables deterministic sequencing and fault logging - PG confirms regulation stability, FLTB isolates fault type and timing.
AEC-Q100 Grade 1 qualification	Validated for −40°C to +125°C ambient operation with full reliability testing - suitable for engine bay and cabin-mounted modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hot-swap protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS25982LVMR (TI)	Lower R_DS(ON) (3.2mΩ), higher max current (30A), but no IMON output; requires external current sense for monitoring.	Preferred where ultra-low loss dominates over integrated diagnostics; lacks analog current reporting capability.	Select when minimizing conduction loss is critical and current monitoring is handled separately.
STIEF01AJR (STMicro)	Integrated current monitor (±5% accuracy), but fixed 10A current limit and no AUTO-configurable fault mode; smaller QFN-16 package.	Suitable for cost-sensitive, single-threshold applications lacking need for field-programmable trip points or recovery modes.	Choose when design requires guaranteed ±5% monitoring accuracy and simplified configuration, accepting fixed current limit.

Compared with TPS25982LVMR and STIEF01AJR, MPQ5069GQV-AEC1-P uniquely combines programmable current limiting (5–15A), ±10% IMON, AUTO-selectable fault recovery, and AEC-Q100 Grade 1 qualification in a single QFN-22 package - making it optimal for automotive subsystems requiring both protection flexibility and embedded diagnostics.

FAQ

What is the minimum soft-start time when the SS pin is left floating?

When the SS pin is floating, the MPQ5069GQV-AEC1-P defaults to a minimum soft-start time of approximately 1 ms. This is achieved via an internal 4 µA current source charging the MOSFET gate, enabling rapid but controlled output voltage ramp-up for applications with modest output capacitance.

How does the MPQ5069GQV-AEC1-P detect a damaged MOSFET during startup?

The device detects a shorted pass MOSFET by monitoring V_OUT during startup: if V_OUT exceeds V_IN − 1 V before gate turn-on completes, it interprets this as a failed MOSFET and asserts FLTB low while holding the output off. Recovery occurs only after V_OUT drops below that threshold.

Can the PG pin operate independently of VIN and EN status?

Yes - the PG pin functions as an open-drain output that can be pulled up to an external supply (e.g., 3.3V or 5V) even when VIN = 0 V or EN is disabled. Its state reflects only the internal regulation conditions (V_FB, V_GS, V_OUT), enabling early system readiness signaling before main power is applied.

What is the purpose of the PD pin, and how does it affect discharge behavior?

The PD pin connects an internal 500 Ω pull-down resistor between OUT and GND when enabled. It activates automatically when VIN falls below UVLO or EN is near its threshold, ensuring safe discharge of output capacitance during power removal or sleep transitions - preventing floating rails and unintended wake-ups.

How is the current limit value calculated from the R_SET resistor?

The current limit is calculated using I_LIMIT = 0.6 V × 20 kΩ / R_SET. For example, a 10 kΩ R_SET yields 12 A (0.6 × 20,000 / 10,000). Bench data shows 10.5–14.5 A across temperature for this value, confirming design margin for 12 A nominal loads.

Does the MPQ5069GQV-AEC1-P support reverse-voltage protection?

No - the MPQ5069GQV-AEC1-P does not provide reverse-voltage protection. It is designed for unidirectional 6V–28V input operation and relies on external components (e.g., series diode or ideal diode controller) if reverse-battery immunity is required in the application.

What thermal performance can be expected on a standard 2-layer evaluation board?

On the MPS EV5069-QV-00A (2-layer, 8.5 cm × 8.5 cm), θ_JA is 30 °C/W. At 12 A and 7 mΩ R_DS(ON), power dissipation is ~1.0 W, resulting in ~30 °C junction-to-ambient rise - well within the 125 °C max operating junction temperature at 25 °C ambient.
