Product details
Overview
MPM3808CGLE-08-AEC1-Z 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 at a fixed 0.8V output voltage, 2.4MHz switching frequency, and ±2% output regulation over -40°C to +150°C junction temperature-designed for automotive camera modules and ADAS sensor rails.
For engineers reviewing the MPM3808CGLE-08-AEC1-Z datasheet, MPM3808CGLE-08-AEC1-Z pinout, MPM3808CGLE-08-AEC1-Z application, or MPM3808CGLE-08-AEC1-Z equivalent, key selection criteria include its wettable-flank QFN-15 package, FCCM operation across full load range, integrated soft-start current of 16µA (0.8V variant), 120Ω output discharge path, and automotive-grade thermal shutdown at 170°C.
Technical Context
The MPM3808CGLE-08-AEC1-Z implements constant-on-time (COT) control with VIN feed-forward to maintain stable 2.4MHz switching across 2.5V–6V input, enabling fast transient response without external compensation. Its internal 470nH inductor and matched 50mΩ/26mΩ HS/LS MOSFETs support high-efficiency operation at light loads via FCCM mode.
Fixed-output configuration eliminates FB resistor divider; FB pin is floated. Power Good (PG) asserts high when VFB exceeds 90% of 0.6V reference, and the 15-pin QFN package integrates wettable flanks for automated optical inspection-critical for automotive PCB assembly traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% (0.784V–0.816V), eliminating external feedback resistors and reducing BOM count. |
| Max Output Current | 3A continuous, supported by integrated 470nH inductor with 5.4A saturation current and low 25mΩ DCR. |
| Switching Frequency | 2.4MHz nominal (2.0–2.7MHz), enabling compact external capacitors and minimizing EMI in space-constrained automotive modules. |
| Input Voltage Range | 2.5V to 6V, compatible with 3.3V and 5V automotive supply rails and surviving cold-crank transients down to 2.5V. |
| Thermal Protection | Thermal shutdown at 170°C with 20°C hysteresis, ensuring safe operation under sustained 3A load in sealed ADAS enclosures. |
| Soft-Start Current | 16µA typical (0.8V variant), enabling precise start-up slew rate control with <10ms soft-start time using 6.8nF capacitor. |
| Output Discharge | Integrated 120Ω discharge path between OUT and GND during shutdown, preventing residual voltage hold-up on downstream logic. |
Pinout & Package
MPM3808CGLE-08-AEC1-Z is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad, optimized for automotive reflow profiling and AOI verification. Pin 15 (DNC) is internally connected to SW and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference input | Floated in fixed-output version; no external divider required-reduces layout sensitivity and improves noise immunity. |
| 2 PG | Open-drain power-good indicator | Pulled high when VFB ≥ 90% of 0.6V; used for system-level power sequencing and fault detection in camera SoCs. |
| 3 VIN | Main input supply | Accepts 2.5V–6V; requires local 10µF ceramic decoupling to suppress high-frequency ripple from adjacent RF modules. |
| 4–6 SW | Switch node connection | Internally tied to high-side P-MOSFET drain and integrated inductor; critical for minimizing loop area and EMI radiation. |
| 7–9 OUT | Regulated output power rail | Delivers 0.8V/3A; connects directly to processor core or image sensor I/O rails with minimal trace inductance. |
| 10–11 GND | Power ground return | Must be tied to large copper pour and multiple vias to thermal pad-ensures low-impedance return path for 3A switching current. |
| 12 EN | Enable control input | Logic-compatible (0.9V rise / 0.65V fall thresholds); supports power sequencing with microcontroller GPIO or PMIC. |
| 13 SS | Soft-start timing control | 16µA charge current enables controlled VOUT ramp; prevents inrush into downstream 0.8V LDOs or memory interfaces. |
| 14 OUT_S | Output voltage sense and discharge path | Provides accurate remote sensing and activates 120Ω discharge FET during shutdown-prevents back-powering. |
| 15 DNC | No-connect terminal | Internally bonded to SW; must not be routed or soldered-avoids unintended short circuits in dense automotive layouts. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +150°C junction operation, meeting automotive reliability requirements for front-end camera modules. |

| Wettable-flank QFN package | Enables automated optical inspection of solder joints-mandatory for zero-defect automotive manufacturing audits. |
| FCCM across full load range | Maintains constant 2.4MHz frequency from 0A to 3A, simplifying EMI filter design and improving predictability in safety-critical systems. |
| Short-circuit protection with hiccup mode | Enters periodic restart cycle upon dead-short detection, limiting average power dissipation to <100mW during fault-prevents thermal runaway. |

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 | 2A max output, 1.8V fixed option only; no 0.8V variant; uses different soft-start architecture (internal, non-adjustable). | Limited to lower-current infotainment peripherals; lacks AEC-Q100 Grade 1 rating for under-hood use. | Select only for non-automotive portable applications where 0.8V and 3A are not required. |
| RTQ2134BGQW | 3A output but 0.6V–3.3V adjustable only; requires external resistor divider and compensation; no wettable flank package. | Suitable for lab validation but fails automotive AOI requirements due to standard QFN footprint. | Choose only if programmable output voltage is mandatory and AEC-Q100 compliance is not required. |

FAQ
What is the purpose of the OUT_S pin on MPM3808CGLE-08-AEC1-Z?
The OUT_S pin serves dual functions: it provides remote output voltage sensing for improved regulation accuracy and acts as the control node for the internal 120Ω output discharge FET during shutdown. When enabled, it discharges the output capacitor to GND within 200µs, preventing back-powering of downstream circuitry-a critical feature for automotive functional safety compliance.
Can MPM3808CGLE-08-AEC1-Z operate with input voltage below 2.5V?
No. The device incorporates an under-voltage lockout (UVLO) with a rising threshold of 2.45V and hysteresis of 0.2V. Operation below 2.3V is prohibited; attempting to power the IC at 2.2V or lower will keep it in shutdown state, with EN inactive and PG low. This ensures reliable startup only after stable battery or supply rail establishment.
How does the soft-start current differ between MPM3808CGLE-08-AEC1-Z and other MPM3808C variants?
The 0.8V fixed-output variant (MPM3808CGLE-08-AEC1-Z) uses a dedicated 16µA soft-start current, versus 3µA for adjustable and 1.2V/1.8V versions. This higher current enables faster, more predictable VOUT ramp times-e.g., 8ms with 6.8nF capacitor-critical for avoiding reset faults in 0.8V processor cores during cold-start sequences.
Is the FB pin required to be terminated in the MPM3808CGLE-08-AEC1-Z?
No. In the fixed-output 0.8V version, the FB pin must be left floating per datasheet specification. Connecting any external impedance-including pull-up/down resistors or capacitors-disrupts internal reference routing and may cause regulation failure or instability. Floating FB ensures correct internal feedback path activation for the factory-trimmed 0.8V output.
What thermal derating applies to MPM3808CGLE-08-AEC1-Z at 105°C ambient?
With θJA = 65°C/W on a standard 4-layer board, maximum power dissipation at 105°C ambient is limited to (150°C − 105°C) / 65°C/W = 0.69W. At 3A output and 0.8V, this corresponds to ~2.3A practical current limit before thermal shutdown triggers-requiring adequate copper area and thermal vias beneath the exposed pad for full 3A operation.
Does MPM3808CGLE-08-AEC1-Z support pre-biased start-up?
Yes. The IC initiates soft-start regardless of initial VOUT voltage-even if the output is pre-charged to 0.8V by another source. During pre-biased start-up, the internal discharge FET remains off until EN is asserted, preventing conflict with external supplies. This enables safe hot-plug operation in modular automotive ECUs.
How is short-circuit protection implemented in hiccup mode?
Upon detecting VFB < 50% of 0.6V (indicating dead short), the IC disables switching, discharges the SS capacitor, and waits ~10ms before restarting soft-start. If the fault persists, it repeats the cycle-limiting average power to <100mW and preventing thermal damage while maintaining visibility via PG pin toggling for diagnostic logging.
