Used in automotive ADAS sensors and camera modules where space, thermal performance, and functional safety are critical.
For engineers reviewing the MPM3806CGLE-18-AEC1-Z datasheet, MPM3806CGLE-18-AEC1-Z pinout, MPM3806CGLE-18-AEC1-Z application, or MPM3806CGLE-18-AEC1-Z equivalent, this page delivers verified technical context, validated pin functions, automotive-grade thermal and EMC specifications, and real-world design implications for camera power rails and sensor supply domains.
Technical Context
The MPM3806CGLE-18-AEC1-Z employs constant-on-time (COT) control with VIN feed-forward to maintain stable 2.4MHz switching across 2.5V–5.5V input and full load range, enabling fast transient response without external loop compensation. Its FCCM operation ensures consistent frequency under light and heavy loads, reducing EMI filtering complexity.
It integrates a wettable-flank QFN-15 (3mm×4mm×1.6mm) package with MeshConnect™ flip-chip construction for enhanced thermal dissipation and solder-joint inspection. Internal protections include cycle-by-cycle peak/valley current limiting (2.5A/1A), hiccup-mode short-circuit protection, thermal shutdown at 170°C, and output over-voltage protection triggered at 115% of VREF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±1.8% (1.764V–1.836V) - eliminates external feedback resistors and improves regulation accuracy in automotive sensor rails. |
| Max Output Current | 1A continuous - supports power-hungry image sensors and radar front-ends without external current boosting. |
| Switching Frequency | 2.4MHz typical - enables use of small external capacitors and avoids AM radio band interference. |
| Input Voltage Range | 2.5V to 5.5V - compatible with automotive 3.3V and 5V supply domains, including post-LDO or battery-supervised rails. |
| Thermal Rating | Junction temperature range −40°C to +150°C - meets AEC-Q100 Grade 1 requirements for under-hood and ADAS module placement. |
| Protection Features | Short-circuit hiccup mode, thermal shutdown (170°C), output OVP (115% VREF), and PG indicator - enables fail-safe behavior in ASIL-B–aligned systems. |
| Package | QFN-15 (3mm×4mm×1.6mm) with wettable flanks - supports automated optical inspection (AOI) and improves board-level reliability in vibration-prone automotive environments. |
Pinout & Package
MPM3806CGLE-18-AEC1-Z is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad. Pin 15 (DNC) is internally tied to SW and must remain unconnected; routing or vias beneath it are prohibited.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference | Internally connected to 0.6V reference; float for 1.8V fixed-output operation - removes need for external resistor divider and associated layout sensitivity. |
| 2 PG | Power good open-drain output | Asserts high when VFB ≥90% of 0.6V (≥540mV); pulls low at ≤85% (≤510mV) - provides system-level fault detection for camera boot sequencing and watchdog integration. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local ceramic decoupling - supports direct connection to automotive 3.3V or 5V domain supplies with minimal input capacitance. |
| 4–6 SW | Switch node | Drain of internal high-side P-MOSFET; directly bonded to integrated inductor - forms core switching path; demands tight layout to minimize dv/dt noise and EMI. |
| 7–9 OUT | Regulated output | Delivers 1.8V to load; connects to output capacitor and sense path - multiple pins reduce IR drop and improve current sharing in compact camera PCBs. |
| 10–11 GND | Power ground | Common return for input/output caps and IC substrate - requires large copper pour and multiple vias to thermal pad for thermal management and noise suppression. |
| 12 EN | Enable control | Active-high logic (0.9V threshold); internal 2MΩ pull-down - enables precise power sequencing with MCU GPIO or PMIC rail controllers in multi-rail ADAS ECUs. |
| 13 SS | Soft-start timing | Charged by 3µA internal current; CSS ≥1nF sets ramp time - prevents inrush into camera sensor's input capacitance and avoids brownout during startup. |
| 14 OUT_S | Output discharge path | Internal 150Ω discharge path to GND when disabled - ensures rapid VOUT collapse for safe reset in camera modules, avoiding latch-up or ghost power. |
| 15 DNC | No-connect | Internally tied to SW; no routing or vias allowed - violation causes short-circuit risk and thermal failure in production assembly. |
Key Features
| Feature | Design Value |
|---|---|
| FCCM operation across full load range | Maintains constant 2.4MHz switching from zero to 1A - simplifies EMI filter design and eliminates audible noise in infotainment and camera subsystems. |
| Integrated 470nH inductor with 25mΩ DCR | Eliminates external magnetics and reduces BOM count by 3–5 components - accelerates layout, improves yield, and shrinks footprint to <12mm² total solution size. |
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +150°C operation with full electrical test coverage - satisfies functional safety requirements for non-ASIL but mission-critical ADAS perception modules. |
| Wettable flank QFN package | Enables AOI-compatible solder joint inspection - critical for zero-defect manufacturing in automotive Tier-1 camera module production lines. |
| Pre-biased soft-start capability | Starts cleanly even when output is pre-charged - essential for hot-swap scenarios in V2X gateways and modular ADAS sensor clusters. |

FAQ
What is the exact output voltage tolerance for MPM3806CGLE-18-AEC1-Z?
The device delivers a fixed 1.8V output with ±1.8% tolerance (1.764V to 1.836V) over −40°C to +150°C junction temperature and full load range, as specified in the Electrical Characteristics table under "Output regulation voltage (1.8V fixed output)".
Can the MPM3806CGLE-18-AEC1-Z operate with input voltage as low as 2.5V while sustaining 1A output?
Yes. The device is fully specified to deliver 1A continuous output down to VIN = 2.5V, maintaining regulation and thermal stability within its −40°C to +150°C operating range, enabled by 100% duty cycle capability and low RDS(ON) MOSFETs (75mΩ/45mΩ).
Is external feedback required for the 1.8V fixed-output version?
No. Pin 1 (FB) must be left floating for fixed-output variants like MPM3806CGLE-18-AEC1-Z. Internal resistor dividers set VOUT = 1.8V; connecting external components to FB invalidates regulation and may cause instability or overvoltage.
How does the PG pin behave during startup and fault conditions?
PG remains low until VFB reaches ≥90% of 0.6V (≥540mV), then pulls high via external pull-up. If VFB drops to ≤85% (≤510mV) due to overload or OVP, PG pulls low within 80µs. During shutdown or EN deassertion, PG defaults low after soft-start discharge completes.
Does the MPM3806CGLE-18-AEC1-Z support pre-biased output startup?
Yes. The device initiates soft-start regardless of initial VOUT voltage - critical for hot-plug camera modules or systems with shared power rails. Pre-biased start-up functions even when output discharge is blocked via external capacitor between OUT and OUT_S.
What is the purpose of the OUT_S pin, and can it be left unconnected?
OUT_S provides a dedicated 150Ω discharge path to GND when the device is disabled, ensuring rapid VOUT collapse. It must be connected to GND through the internal path; leaving it floating disables discharge and risks unsafe residual voltage in camera sensor interfaces.
Is the QFN-15 package RoHS and halogen-free compliant?
Yes. All MPS parts, including MPM3806CGLE-18-AEC1-Z, are lead-free, halogen-free, and fully compliant with the EU RoHS directive. Full green status documentation is available on the Monolithic Power Systems Quality Assurance webpage.
