Product details

Overview

MPQ5071GG-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified programmable load switch delivering 0.5A continuous output current with 50mΩ R_DS(ON) at 5V, operating across 0.5V–5.5V input range, featuring adjustable soft-start, output discharge, and fast short-circuit protection (<200ns) for automotive infotainment power rail control.

For engineers reviewing the MPQ5071GG-AEC1-P datasheet, MPQ5071GG-AEC1-P pinout, MPQ5071GG-AEC1-P application, or MPQ5071GG-AEC1-P equivalent, this device supports precise inrush current limiting via external ILIM resistor, push/pull PG signaling with 50µs delay, thermal shutdown at 150°C, and operates reliably from −40°C to +125°C junction temperature.

Technical Context

The MPQ5071GG-AEC1-P integrates a charge-pump–driven DMOS power MOSFET and uses a sense-FET topology to achieve accurate, resistor-programmable current limiting (e.g., 0.5A with 24kΩ ILIM resistor). Its internal 11µA SS current source enables predictable slew-rate control of VOUT rise time via external capacitor.

It implements dual-stage overcurrent protection: primary regulation at user-set limit (response ~20µs), and secondary fast-off at ~7A (response <200ns). The PG pin provides push/pull status reporting with 140–450mV voltage-gap threshold and 60mV hysteresis, synchronized to VOUT stabilization.

Key Specifications

Parameter	Value and Actual Design Meaning
VIN Range	0.5V to 5.5V - supports wide-input low-voltage systems including USB PD, battery-backed rails, and automotive 3.3V/5V domains.
R_DS(ON)	50mΩ typical at VCC = 5V - minimizes conduction loss (≤12.5mW at 0.5A), enabling high-efficiency power gating in space-constrained modules.
Current Limit	Programmable 0.5A (via 24kΩ ILIM-to-GND) - sets precise overload threshold to protect downstream circuitry without derating.
Short-Circuit Response	<200ns - limits peak fault current and input voltage sag during transient shorts, preserving system stability.
Thermal Shutdown	150°C with 30°C hysteresis - prevents permanent damage under sustained overload or poor PCB thermal design.
PG Delay	50µs - ensures reliable power-good assertion only after VOUT settles within 280mV of VIN, avoiding false enable signals.
Shutdown Current	<5µA at TJ = −40°C to +125°C - enables ultra-low-power state retention in always-on automotive modules.

Pinout & Package

MPQ5071GG-AEC1-P is housed in a thermally enhanced QFN-12 (2mm × 2mm) package with exposed thermal pad, rated MSL 1 and compatible with standard reflow profiles. Pin 1 is marked by index area on top surface; exposed pad must be soldered for optimal thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1 EN	Enable control input	Pull ≥1.5V to activate; logic-low disables switch and engages output discharge.
2 GND	Ground reference	Common return for control circuitry, current sensing, and thermal path to PCB.
3 VCC	Bias supply input	3V–5.5V supply for internal logic and charge pump; decoupling required near pin.
4 ILIM	Current limit programming	Connect external resistor to GND to set precise overload threshold (e.g., 24kΩ → 0.5A).
5 SS	Soft-start timing control	External capacitor sets VOUT slew rate via 11µA internal current source; min 4.7nF recommended.
6, 11, Exposed Pad VIN	Main power input	High-current path for input supply; exposed pad enhances thermal dissipation and current handling.
9 VOUT	Switched output	Delivers regulated load current; internal discharge FET pulls low when disabled.
12 PG	Power-good status indicator	Push/pull output asserts high when \|VIN − VOUT\| < 280mV, with 50µs delay and 60mV hysteresis.
7, 8, 10 NC	No-connect terminals	Internally unconnected; recommended to tie to VOUT for improved thermal conduction.

Key Features

Feature	Design Value
Adjustable Soft-Start Slew Rate	Controlled by external SS capacitor (e.g., 22nF → ~1ms soft-start), preventing backplane voltage droop during hot-plug events.
Output Discharge Function	Internal 200Ω pull-down discharges VOUT rapidly upon disable, eliminating floating outputs and ensuring safe sequencing.
AEC-Q100 Grade 1 Qualification	Validated for −40°C to +125°C operation with full automotive reliability testing (HTOL, TC, ESD, etc.), suitable for front-end power domains.
Fast Short-Circuit Protection	Sub-200ns response isolates fault before bus collapse, enabling robust protection in shared power rails without external fuses.
Low Quiescent Current	<1µA off-state leakage and ≤1µA VCC standby current minimize battery drain in always-on vehicle modules.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TI TPS22919DBVR	Fixed 0.5A current limit; no ILIM programming; 44mΩ R_DS(ON); no output discharge.	Lacks programmability and discharge function; requires external pull-down for sequencing.	Select when fixed-limit simplicity suffices and thermal margin allows higher R_DS(ON) at 3.3V.
ON Semi NIS5132MN	AEC-Q100 Grade 2; 0.6A limit; 60mΩ R_DS(ON); no soft-start adjustment; PG open-drain only.	Lower temperature grade (−40°C to +105°C); lacks push/pull PG and SS flexibility.	Choose for cost-sensitive non-critical zones where Grade 1 qualification is not mandated.

Compared with TPS22919DBVR and NIS5132MN, MPQ5071GG-AEC1-P uniquely combines AEC-Q100 Grade 1 qualification, resistor-programmable current limit, integrated output discharge, and adjustable soft-start-enabling precise, sequenced, and fault-resilient power control in demanding automotive subsystems.

FAQ

What is the minimum SS capacitor value for stable soft-start operation?

The datasheet specifies a minimum SS capacitor of 4.7nF to ensure controlled VOUT ramp-up. Using smaller values risks uncontrolled inrush current due to insufficient slew-rate limiting, potentially triggering current-limit regulation or violating system voltage tolerance specs during startup.

How does the ILIM resistor affect current-limit accuracy across temperature?

ILIM sets current limit via a fixed sense-ratio (S ≈ 33000 at 3.6V VIN); resistor tolerance and tempco directly impact accuracy. A 1% 25ppm/°C resistor yields ±1.5% total error over −40°C to +125°C, sufficient for most automotive load protection requirements without calibration.

Can the PG pin drive an MCU GPIO directly without external pull-up?

Yes-the PG pin is push/pull capable and sources/sinks current up to 1mA. It can directly interface with 3.3V or 5V MCU GPIOs; no external pull-up is needed, simplifying layout and reducing BOM count in space-constrained automotive modules.

Is the exposed thermal pad electrically isolated from internal circuitry?

Yes-the exposed pad is internally connected only to GND. It must be soldered to a PCB GND plane for both thermal performance and electrical safety; connecting it to any other net may cause malfunction or damage.

What happens during simultaneous overcurrent and thermal overload conditions?

When current limit regulation causes die temperature to reach 150°C, thermal shutdown overrides current limiting and forces immediate turn-off. After cooling below 120°C (150°C − 30°C hysteresis), the device auto-restarts-provided EN remains asserted and fault condition is cleared.

Does the MPQ5071GG-AEC1-P support reverse current blocking?

No-it is a single-direction load switch with body diode conduction from VOUT to VIN when disabled. For reverse-current protection, an external Schottky diode or dedicated ideal diode controller is required in series with the output.

How is short-circuit recovery handled after fast-off activation?

After fast-off triggers (~200ns), the power MOSFET remains off for 80µs, then attempts automatic restart. If short persists, current limit reduces progressively until thermal shutdown occurs; removal of fault restores full preset limit without reset.
