Product details
Overview
MPM3807GLE-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 2A continuous output current, 2.5V–5.5V input range, and 0.6V feedback reference voltage. It operates across –40°C to +150°C junction temperature and features constant-on-time (COT) control for fast transient response-ideal for automotive ADAS sensors requiring compact, high-reliability DC/DC conversion.
For engineers reviewing the MPM3807GLE-AEC1-P datasheet, MPM3807GLE-AEC1-P pinout, MPM3807GLE-AEC1-P application, or MPM3807GLE-AEC1-P equivalent, key selection criteria include its wettable-flank QFN-15 package, 2.4MHz switching frequency, integrated 70mΩ/40mΩ MOSFETs, 21µA sleep-mode IQ, and PG signal with 90% VFB threshold-critical for automotive power sequencing and functional safety compliance.
Technical Context
The MPM3807GLE-AEC1-P implements a VIN feed-forward constant-on-time (COT) control architecture with internal 0.6V reference and programmable soft-start via external capacitor. Its COT loop achieves stable 2.4MHz operation across 2.5V–5.5V input while maintaining <±1% FB accuracy and <0.3% load regulation at 2A.
It integrates a 470nH inductor with 25mΩ DCR, dual power MOSFETs (70mΩ HS, 40mΩ LS), and protection circuitry including cycle-by-cycle current limiting (2.5–4.5A peak), thermal shutdown at 170°C, and hiccup-mode OVP/SCP. The adjustable-output variant uses external resistor divider on FB, while PG provides open-drain status at 90% of nominal VOUT.
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 (≥2.5V) and load-dump transients (≤5.5V). |
| Output Current | 2A continuous - sufficient for powering dual-core ADAS SoCs or multi-sensor camera modules without external heatsinking. |
| Switching Frequency | 2.4MHz typical - enables use of small external capacitors and reduces EMI filter size for space-constrained automotive PCBs. |
| Feedback Accuracy | ±1% at TJ = –40°C to +150°C - ensures stable core voltage regulation under extreme under-hood thermal conditions. |
| Quiescent Current | 21µA in sleep mode - extends battery life in always-on vehicle subsystems such as parking cameras or V2X wake-up receivers. |
| Thermal Shutdown | 170°C with 20°C hysteresis - prevents permanent damage during sustained overload or poor airflow in sealed enclosures. |
| Power Good Threshold | 90% of VFB rising - provides precise, glitch-filtered enable signaling for downstream processors requiring tight power-rail sequencing. |
Pinout & Package
MPM3807GLE-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 environments. The package supports automated optical inspection (AOI) and improves solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Connects to external resistor divider to set output voltage; internally referenced to 0.6V; float for fixed-output versions. |
| 2 PG | Open-drain power good | Asserts high when VFB ≥ 90% of 0.6V; requires external pull-up; used for system power sequencing and fault monitoring. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local ceramic decoupling; UVLO triggers at 2.45V rising edge. |
| 4–6 SW | Switch node | Internal connection to high-side MOSFET drain and integrated inductor; carries high di/dt switching current. |
| 7–9 OUT | Power output | Delivers regulated output to load; connects directly to output capacitor and load; low-impedance path for 2A current. |
| 10–11 GND | Ground reference | Common return for input/output caps and IC logic; must be tied to large copper plane with multiple vias for thermal and EMI performance. |
| 12 EN | Enable control | Digital input: >0.9V enables, <0.65V disables; includes 2MΩ internal pull-down for default-off behavior. |
| 13 SS | Soft-start timing | Connects to external capacitor to control ramp rate; minimum 1nF recommended to limit inrush current during startup. |
| 14 OUT_S | Output sense & discharge | Senses VOUT for regulation and provides 150Ω discharge path to GND when disabled-prevents floating output during shutdown. |
| 15 DNC | No-connect | Internally tied to SW; must remain unconnected and un-routed to avoid parasitic coupling or short circuits. |

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 1.2A output current; 2.5V–6V input; no PG pin; 1.2mm height vs. 1.6mm | Targeted at space-constrained portable electronics-not AEC-Q100 qualified | Select only for non-automotive, low-current applications where PG signaling and automotive qualification are unnecessary. |
| RTQ2132BGQW | 2.5A output; 2.7V–18V input; integrated compensation; no wettable flanks; 17-pin QFN | Designed for industrial 12V/24V systems-lacks AEC-Q100 Grade 1 thermal rating and automotive-specific protections | Prefer for higher-input industrial designs where extended VIN range outweighs automotive qualification needs. |
Compared with TPS82084SILR and RTQ2132BGQW, the MPM3807GLE-AEC1-P uniquely combines AEC-Q100 Grade 1 qualification, wettable-flank inspection capability, integrated 470nH inductor, and PG signaling-making it the only drop-in solution for production automotive ADAS and infotainment power rails requiring zero design requalification.

FAQ
What is the purpose of the OUT_S pin on the MPM3807GLE-AEC1-P?
The OUT_S pin serves dual functions: it provides precise output voltage sensing for regulation feedback and activates an internal 150Ω discharge path to ground when the device is disabled. This ensures rapid, controlled discharge of the output capacitor during shutdown-preventing residual voltage from interfering with downstream logic states or causing latch-up in connected ASICs.
Does the MPM3807GLE-AEC1-P require external compensation components?
No. The MPM3807GLE-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 optional soft-start capacitor. This eliminates tuning effort and reduces design risk compared to controller-based solutions.
How does the constant-on-time (COT) control improve transient response?
COT control directly links switch-on time to output voltage deviation: when VFB drops below 0.6V, the high-side MOSFET turns on immediately for a duration inversely proportional to VIN/VOUT. This eliminates loop compensation delays, achieving sub-10µs recovery from 50% load steps-critical for powering burst-mode processors in ADAS vision systems.
Can the MPM3807GLE-AEC1-P operate with 100% duty cycle?
Yes. The device supports 100% duty cycle operation in dropout mode-when VIN approaches VOUT-by turning off the low-side MOSFET and holding the high-side MOSFET continuously on. This maintains regulation down to VIN = VOUT + 0.5V, enabling seamless operation during automotive cold-crank events where battery voltage dips to 2.5V.
What is the significance of the "AEC1" suffix in the part number?
The "AEC1" suffix denotes full AEC-Q100 Grade 1 qualification, meaning the device has passed stress tests for temperature cycling (–40°C to +150°C), high-temperature operating life (1000 hours at +150°C), and ESD robustness (Class 2 HBM). This certification is mandatory for power ICs used in passenger compartment and engine bay applications.
Is the MPM3807GLE-AEC1-P pin-compatible with other MPM3807 variants?
Yes-all MPM3807 variants (adjustable and fixed-output) share identical QFN-15 pinout, footprint, and thermal pad layout. The MPM3807GLE-AEC1-P (adjustable) differs only in FB pin usage (requires external divider) versus fixed-output versions (FB floated), allowing flexible design reuse across voltage configurations.
What is the maximum achievable efficiency at 2A output current?
At VIN = 3.3V and VOUT = 1.2V, the MPM3807GLE-AEC1-P achieves up to 92% peak efficiency per datasheet Figure 12. Efficiency remains >88% across the full 0.1A–2A load range at 3.3V input, enabled by low RDS(ON) MOSFETs (70mΩ/40mΩ) and optimized gate drive timing.
