Product details

Overview

MPM3808GLE-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with built-in inductor and MOSFETs, delivering up to 3A continuous output current, 2.5V–5.5V input range, and 1% FB voltage accuracy. It operates from –40°C to +150°C junction temperature and features constant-on-time (COT) control for fast transient response in automotive ADAS sensors and camera modules.

For engineers reviewing the MPM3808GLE-AEC1-P datasheet, MPM3808GLE-AEC1-P pinout, MPM3808GLE-AEC1-P application, or MPM3808GLE-AEC1-P equivalent, key selection criteria include its wettable-flank QFN-15 package, 2.4MHz switching frequency, integrated 376–564nH inductor, 21µA sleep-mode IQ, and PG/EN/SS/OUT_S functional pins for automotive power sequencing and diagnostics.

Technical Context

The MPM3808GLE-AEC1-P implements a constant-on-time (COT) control architecture with VIN feed-forward, enabling stable 2.4MHz switching across 2.5V–5.5V input and maintaining tight regulation under dynamic load transients. Its internal high-side P-channel (65mΩ R_DS(ON)) and low-side N-channel (35mΩ R_DS(ON)) MOSFETs are co-packaged with a 470nH integrated inductor and compensation network.

It supports adjustable-output configuration via external FB resistor divider (0.6V reference), includes zero-current detection (50mA threshold) for DCM operation, and employs Advanced Asynchronous Modulation (AAM) with 150ns blanking time to sustain high light-load efficiency down to 21µA quiescent current.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.5V to 5.5V - supports wide automotive battery rail variation including cold-crank and load-dump conditions.
Output Current	Up to 3A continuous - sufficient for powering image signal processors (ISPs), radar SoCs, and microcontrollers in ADAS ECUs.
Switching Frequency	2.4MHz typical - enables compact external filtering and reduces EMI fundamental energy in sensitive RF bands.
Feedback Accuracy	±1% at TJ = 25°C - ensures precise core voltage regulation for automotive-grade DSPs and MCUs requiring tight VDD tolerance.
Quiescent Current	21µA in sleep mode - extends battery life in always-on vehicle subsystems such as parking cameras and V2X wake-up receivers.
Junction Temperature Range	–40°C to +150°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin-mounted electronics.
Thermal Resistance θJA	65°C/W on JESD51-7 4-layer board - enables thermal design margin for 3A loads without forced airflow in sealed enclosures.

Pinout & Package

MPM3808GLE-AEC1-P is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad for enhanced heat dissipation in automotive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 FB	Feedback input	Connects to external resistor divider for adjustable output; internally referenced to 0.6V; float for fixed-output variants.
2 PG	Power good indicator	Open-drain output asserting high when V_FB ≥ 90% of 0.6V; used for system power sequencing and fault monitoring.
3 VIN	Main input supply	Accepts 2.5V–5.5V; requires local ceramic decoupling to suppress high-frequency switching noise.
4–6 SW	Switch node	Internal high-side MOSFET drain connected to integrated inductor; carries high di/dt; must be routed with minimal loop area.
7–9 OUT	Power output	Delivers regulated DC output; connects directly to load and output capacitor; multiple pins reduce IR drop and improve current sharing.
10–11 GND	Ground reference	Primary IC ground return; must be tied to large copper pour and multiple vias to minimize impedance and thermal resistance.
12 EN	Enable control	Digital enable with 0.9V rising / 0.65V falling thresholds; internal 2MΩ pull-down enables default-off safety behavior.
13 SS	Soft-start timing	External capacitor sets controlled V_OUT ramp rate; 3µA internal charge current prevents inrush into downstream capacitance.
14 OUT_S	Output sense & discharge	Provides precision feedback path and internal 150Ω discharge path to GND during shutdown for rapid V_OUT collapse.
15 DNC	No-connect	Internally tied to SW; must remain unconnected and un-routed to avoid parasitic coupling or solder bridging.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from –40°C to +150°C T_J, including HTOL, TC, and ESD testing per AEC standards.
Integrated inductor + MOSFETs	Eliminates 6–8 external components (inductor, HS/LS FETs, bootstrap cap, compensation network), reducing BOM count and layout area by >40%.
MeshConnect™ flip-chip packaging	Reduces parasitic inductance and improves thermal conduction from die to PCB, lowering peak junction temperature by up to 15°C vs. wire-bond QFN.
Wettable flank leads	Enables automated optical inspection (AOI) of solder joints on bottom-side terminations-critical for automotive manufacturing traceability.
100% duty cycle capability	Supports LDO-like operation near dropout (e.g., V_IN = 2.7V → V_OUT = 2.5V), essential for battery-powered vision systems during cold-crank events.

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous step-down power module applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS82084SILR	Lower I_OUT (2A), 1.8V–6V input, no wettable flank, 0.6V FB reference, 2.2MHz f_SW	Lacks AEC-Q100 qualification; rated only for industrial temp (–40°C to +85°C); unsuitable for under-hood deployment.	Select only for non-automotive infotainment or portable test equipment where AEC compliance is not required.
RTQ2132BGQW	3A output, 2.7V–6V input, AEC-Q100 Grade 2 (–40°C to +105°C), 0.6V FB, 2.1MHz f_SW, no integrated inductor	Requires external inductor and compensation components; larger total solution size; lower max T_J limits placement near heat sources.	Prefer when design flexibility (e.g., custom inductance value or saturation current) outweighs board-area savings and thermal performance.

Compared with TPS82084SILR and RTQ2132BGQW, MPM3808GLE-AEC1-P uniquely combines AEC-Q100 Grade 1 qualification, wettable flank inspection capability, integrated inductor, and 150°C junction rating-making it the only option suitable for thermally demanding, safety-critical ADAS camera and radar power rails.

FAQ

What is the function of the OUT_S pin on the MPM3808GLE-AEC1-P?

The OUT_S pin serves dual functions: it provides a dedicated low-impedance sensing path for output voltage feedback (improving regulation accuracy), and activates an internal 150Ω discharge path to GND during shutdown-ensuring rapid V_OUT collapse for safe power sequencing in automotive systems with multiple voltage domains.

Does the MPM3808GLE-AEC1-P require external compensation components?

No. The MPM3808GLE-AEC1-P integrates a complete compensation network-including error amplifier, ramp generator, and internal resistors/capacitors-enabling stable operation with only input/output capacitors and (for adjustable versions) an external FB resistor divider. This eliminates tuning effort and reduces bill-of-materials count.

How does the constant-on-time (COT) control improve transient response?

COT control directly links high-side switch on-time to output voltage deviation from the 0.6V reference, bypassing traditional error amplifier loop dynamics. This yields sub-microsecond response to load steps-verified at <5µs for 0→3A transitions-critical for powering burst-mode image sensors and radar processors without output droop or overshoot.

Can the MPM3808GLE-AEC1-P operate with a 2.5V input and 2.4V output?

Yes. With its 100% duty-cycle capability and low dropout characteristics, the MPM3808GLE-AEC1-P supports V_OUT = 2.4V at V_IN = 2.5V while maintaining regulation-enabling operation during automotive cold-crank events where battery voltage dips below 6V, and eliminating need for supplemental LDO stages.

What protection features are implemented in the MPM3808GLE-AEC1-P?

The device includes cycle-by-cycle current limiting (peak: 4–6A, valley: 1.5–4.5A), thermal shutdown at 170°C with 20°C hysteresis, input over-voltage protection (6.15V), output over-voltage protection (110–120% of V_FB), short-circuit hiccup mode, and reverse-current blocking-providing comprehensive fault coverage for unattended automotive deployments.

Is the MPM3808GLE-AEC1-P pin-compatible with other MPM3808 variants?

Yes. All MPM3808 variants-including MPM3808GLE-12-AEC1 and MPM3808GLE-18-AEC1-share identical QFN-15 (3mm×4mm) pinout and footprint. Only the FB pin connection differs (external divider for adjustable, floating for fixed), allowing hardware reuse across output voltage variants in platform-based automotive designs.
