Product details
Overview
MPM3806CGLE-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with embedded MOSFETs and inductor, delivering up to 1A continuous output current at 0.6V–VIN−0.5V from a 2.5V–5.5V input, featuring constant-on-time (COT) control, 2.4MHz switching frequency, and open-drain power good (PG) signal - deployed in automotive ADAS sensors and camera modules.
For engineers reviewing the MPM3806CGLE-AEC1-Z datasheet, MPM3806CGLE-AEC1-Z pinout, MPM3806CGLE-AEC1-Z application, or MPM3806CGLE-AEC1-Z equivalent, key selection criteria include its wettable-flank QFN-15 package, adjustable-output configuration (FB-based feedback), -40°C to +150°C junction temperature rating, FCCM operation across full load range, and integrated OVP/SCP/hiccup-mode protection for automotive-grade reliability.
Technical Context
The MPM3806CGLE-AEC1-Z implements input-voltage feed-forward constant-on-time (COT) control with fixed minimum off-time (80ns) to ensure stable 2.4MHz switching across 2.5V–5.5V VIN and full load range, enabling fast transient response without external compensation. Its FCCM architecture maintains continuous inductor current under all loads, reducing output ripple and EMI sensitivity.
Internal protection logic includes cycle-by-cycle peak current limiting (2.5A typical), valley current limiting (1A typical), thermal shutdown at 170°C with 20°C hysteresis, and dynamic over-voltage regulation triggered at 115% VREF - all coordinated with PG assertion thresholds (90% rising / 85% falling of VFB = 0.6V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports direct connection to automotive 3.3V/5V rails and battery-supervised systems with UVLO at 2.45V (rising) |
| Output Current | 1A continuous - sustained at TJ ≤ 150°C with θJA = 65°C/W on standard 4-layer PCB |
| Switching Frequency | 2.4MHz ±10% - enables compact external filtering and meets CISPR-25 Class 5 EMI requirements in automotive layouts |
| Feedback Accuracy | ±1% at TJ = −40°C to +150°C - ensures tight output regulation for DSP and image sensor power domains |
| Thermal Shutdown | 170°C with 20°C hysteresis - protects against sustained overload or poor heatsinking in enclosed automotive enclosures |
| Power Good Threshold | 90% of 0.6V (0.54V) rising / 85% (0.51V) falling - provides robust sequencing margin for downstream logic and ADC references |
| Soft-Start Control | External capacitor (≥1nF) on SS pin - sets controlled VOUT ramp rate to prevent inrush into capacitive loads like CMOS image sensors |
Pinout & Package
MPM3806CGLE-AEC1-Z uses a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad, optimized for automated optical inspection (AOI) and solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Resistor-divider tap point for adjustable output; internal 0.6V reference comparison node - float for fixed-output variants |
| 2 PG | Open-drain power good indicator | Pulled low during startup/fault; high when VFB ≥ 90% of 0.6V - requires external pull-up (10kΩ–100kΩ) to valid supply rail |
| 3 VIN | Main input supply | 2.5V–5.5V source connection; decoupling capacitor must be placed adjacent to minimize high-frequency loop inductance |
| 4–6 SW | Switch node | Drain of internal high-side P-MOSFET; directly bonded to integrated inductor - critical for EMI layout and thermal path |
| 7–9 OUT | Regulated output | Delivers up to 1A; connects to load and output capacitor - multiple pins reduce IR drop and improve current sharing |
| 10–11 GND | Power ground | Common return for input/output caps and IC core; requires large copper pour and multiple vias to internal ground plane |
| 12 EN | Enable control | Digital ON/OFF with 0.9V rising / 0.65V falling threshold; internal 2MΩ pull-down enables default-off behavior |
| 13 SS | Soft-start timing | Charged at 3µA to set VOUT ramp time; 1nF yields ~0.2ms soft-start - prevents overshoot into pre-biased loads |
| 14 OUT_S | Output sense & discharge path | Sense node for output discharge MOSFET; connects to 150Ω internal discharge resistor when EN = low |
| 15 DNC | No-connect | Internally tied to SW; must remain unconnected and un-routed - avoids parasitic coupling and thermal stress |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +150°C junction operation with full automotive stress testing (HTOL, TC, UHAST) |
| Integrated power train | 75mΩ HS-FET + 45mΩ LS-FET + 470nH inductor in single QFN - eliminates external magnetics and gate drive complexity |
| FCCM across full load | Forced continuous conduction mode ensures constant 2.4MHz switching regardless of load - simplifies EMI filter design |
| Wettable flank package | Side-wettable leads enable AOI-compatible solder joint inspection - critical for zero-defect automotive manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS82084SILR | Fixed 1.2V output only; 1.8MHz switching; no adjustable FB pin; smaller 2.3mm × 2.7mm package | Lacks PG signal and soft-start control; not AEC-Q100 qualified; limited to non-safety-critical consumer-tier modules | Select only for space-constrained, cost-sensitive non-automotive designs where adjustable output and PG are unnecessary. |
| MAX20004AATP+T | 1.2V fixed output; 2.2MHz switching; integrated spread-spectrum; higher 1.2A IOUT rating | Requires external compensation; no wettable flank; AEC-Q100 Grade 0 (−40°C to +125°C), not Grade 1 | Prefer for higher-current applications where extended temperature range is not required and spread-spectrum EMI reduction is prioritized. |

FAQ
What output voltage options does MPM3806CGLE-AEC1-Z support?
The MPM3806CGLE-AEC1-Z is the adjustable-output variant, using an external resistor divider on the FB pin to set VOUT from 0.6V up to VIN − 0.5V. Fixed-output versions (e.g., MPM3806CGLE-12-AEC1-Z for 1.2V) are separate part numbers - this part requires no internal feedback resistors and offers full flexibility for system-level voltage tuning.
Does MPM3806CGLE-AEC1-Z require external compensation components?
No. The MPM3806CGLE-AEC1-Z integrates a complete compensation network internally, enabled by its constant-on-time (COT) control architecture. Only input and output capacitors, plus optional FB divider resistors, are needed - eliminating loop stability analysis and reducing BOM count by up to four passive components.
How is thermal performance validated for automotive under-hood use?
MPM3806CGLE-AEC1-Z is rated for −40°C to +150°C junction operation and features a wettable-flank QFN-15 package with exposed thermal pad. Thermal resistance is characterized at θJA = 65°C/W (JESD51-7, 4-layer board) and θJC = 14°C/W, with thermal shutdown at 170°C and 20°C hysteresis - verified per AEC-Q100 stress test conditions including HTOL and temperature cycling.
Can MPM3806CGLE-AEC1-Z operate with pre-biased outputs?
Yes. The device supports pre-biased start-up: when EN rises above 0.9V, the converter initiates soft-start regardless of existing VOUT voltage. This behavior is retained even when the OUT_S discharge path is blocked by an external capacitor - critical for hot-swap and multi-rail sequencing in infotainment systems.
What protections are implemented beyond over-current and thermal shutdown?
In addition to cycle-by-cycle current limiting and thermal shutdown, MPM3806CGLE-AEC1-Z includes input over-voltage protection (6.15V trip), output over-voltage regulation (115% VREF dynamic clamp), short-circuit protection with hiccup-mode recovery, and undervoltage lockout (2.45V rising). All protections are fully integrated and require no external circuitry.
Is the PG signal compatible with 1.8V or 3.3V logic interfaces?
Yes. The PG pin is open-drain and can be pulled up to any valid logic rail (1.8V, 3.3V, or 5V) via a 10kΩ–100kΩ resistor. Its sink capability exceeds 1mA at 0.4V, ensuring solid low-state drive into standard CMOS inputs - verified across −40°C to +150°C operating range.
How does the wettable flank feature impact manufacturing yield?
The wettable flank design exposes vertical sidewalls of each QFN lead, enabling automated optical inspection (AOI) of solder fillet formation during reflow. This significantly improves first-pass yield in automotive SMT lines by detecting insufficient solder, bridging, or tombstoning - a requirement for IATF 16949-certified production.
