For engineers reviewing the MPM3807CGLE-12-AEC1-Z datasheet, MPM3807CGLE-12-AEC1-Z pinout, MPM3807CGLE-12-AEC1-Z application, or MPM3807CGLE-12-AEC1-Z equivalent, this page provides verified technical context on its COT control architecture, wettable-flank QFN-15 package, PG/EN/SS interface behavior, and automotive-grade thermal and fault-protection specifications - all confirmed against MPS Rev. 1.0 datasheet (Oct 2022).
Technical Context
The MPM3807CGLE-12-AEC1-Z implements constant-on-time (COT) control with VIN feed-forward, enabling stable 2.4MHz switching across full 2.5V–5.5V input range and load conditions. Its forced continuous conduction mode (FCCM) eliminates frequency variation under light load, reducing EMI sensitivity and simplifying EMC filtering.
It integrates a 470nH power inductor with 25mΩ DCR, 70mΩ high-side and 40mΩ low-side MOSFETs, and a dedicated OUT_S sense/discharge path with 150Ω internal discharge resistance. The fixed 1.2V output version internally connects FB to reference, eliminating external resistor divider requirements while retaining EN, PG, SS, and thermal shutdown functions.

Pinout & Package
MPM3807CGLE-12-AEC1-Z uses a 15-pin QFN-15 (3mm × 4mm × 1.6mm) wettable flank package with exposed thermal pad. Pin 15 (DNC) is internally tied to SW and must remain unconnected; pins 4–6 (SW) and 7–9 (OUT) are paralleled for low-impedance power routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference input | Floating in fixed-output mode; internal connection to 0.6V reference ensures precise 1.2V regulation without external resistors. |
| 2 PG | Open-drain power-good indicator | Pulled high when VFB ≥ 90% of 0.6V (≥540mV); pulled low if VFB ≤ 85% (≤510mV) - enables system-level power sequencing and fault detection. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local 10µF ceramic decoupling to suppress high-frequency ripple from 2.4MHz switching. |
| 4–6 SW | Switch node | Internally connected to drain of high-side P-MOSFET and inductor - forms critical high-di/dt loop requiring tight layout with minimal trace length. |
| 7–9 OUT | Regulated output | Delivers 1.2V/2A; paralleled pins reduce DC resistance and improve thermal spreading to PCB copper planes. |
| 10–11 GND | Power and signal ground | Must connect to large thermal pad and multiple vias to inner ground plane - essential for EMI suppression and thermal performance. |
| 12 EN | Enable control | Active-high logic: >0.9V enables, <0.65V disables; internal 2MΩ pull-down allows single-resistor biasing for power sequencing. |
| 13 SS | Soft-start timing | External capacitor (≥1nF) sets controlled VOUT ramp rate; 3µA internal charge current prevents inrush and supports pre-biased start-up. |
| 14 OUT_S | Output sense & discharge path | Provides dedicated low-impedance discharge path (150Ω) during shutdown - avoids hold-up voltage in safety-critical systems. |
| 15 DNC | No-connect | Internally tied to SW; must not be routed or soldered - prevents parasitic coupling and ensures reliable flip-chip thermal performance. |

FAQ
What is the purpose of the OUT_S pin on MPM3807CGLE-12-AEC1-Z?
The OUT_S pin provides a dedicated low-impedance discharge path (150Ω internal resistance) from the output capacitor to ground during shutdown. This ensures rapid VOUT collapse - critical for functional safety in automotive ADAS systems where residual voltage could interfere with sensor reset sequences or violate ASIL-B timing requirements. It operates independently of the main OUT pins and is not used for regulation.
Does MPM3807CGLE-12-AEC1-Z require external compensation components?
No. The MPM3807CGLE-12-AEC1-Z integrates a complete compensation network optimized for its fixed 1.2V output and COT control architecture. Unlike adjustable regulators, it needs no external Type-II or Type-III compensation components - only input and output ceramic capacitors (e.g., 10µF VIN, 22µF VOUT) and optional soft-start capacitor on SS. This reduces design risk and accelerates qualification.
How does the PG pin behave during startup and fault conditions?
The PG pin is an open-drain output that remains low until VFB reaches ≥90% of 0.6V (≥540mV), then pulls high via external pull-up. If VFB drops to ≤85% (≤510mV) during operation - due to overload, short circuit, or input brownout - PG is actively pulled low within 80µs. During pre-biased start-up, PG asserts only after VOUT stabilizes, ensuring accurate power-good assertion independent of initial rail voltage.
Can MPM3807CGLE-12-AEC1-Z operate with input voltage below 2.5V?
No. The device has a hard under-voltage lockout (UVLO) with rising threshold at 2.45V and hysteresis of 0.2V, meaning it will not enable below ~2.25V. Below 2.5V input, the converter remains disabled even if EN is asserted. This is intentional to guarantee stable operation across automotive cold-crank transients and prevent erratic regulation near minimum specified VIN.
What thermal derating applies to MPM3807CGLE-12-AEC1-Z at 150°C junction temperature?
At TJ = 150°C, the device maintains full 2A output capability per datasheet electrical characteristics (VIN = 3.6V, TJ = –40°C to +150°C). Derating begins only when ambient temperature and PCB thermal resistance cause junction temperature to exceed 150°C - at which point thermal shutdown (170°C) activates. With proper 4-layer PCB layout (2oz copper, thermal vias), full 2A load is sustainable up to +105°C ambient.
Is the MPM3807CGLE-12-AEC1-Z pin-compatible with other MPM3807C variants?
Yes. All MPM3807C variants - including adjustable (MPM3807CGLE-AEC1-Z) and fixed-output versions (e.g., -18, -25, -33) - share identical QFN-15 (3mm×4mm×1.6mm) pinout, footprint, and thermal pad layout. Only FB pin handling differs: floating for fixed outputs versus resistor-divider connection for adjustable versions. This enables single PCB design reuse across multiple output voltages.
