Monolithic Power Systems Inc. MPM3807CGLE-12-AEC1-P

Overview

MPM3807CGLE-12-AEC1-P 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 2A continuous output current at fixed 1.2V with ±2% regulation accuracy over -40°C to +150°C junction temperature, operating from 2.5V–5.5V input, and featuring 2.4MHz switching frequency for compact filtering in automotive ADAS sensor rails.

For engineers reviewing the MPM3807CGLE-12-AEC1-P datasheet, MPM3807CGLE-12-AEC1-P pinout, MPM3807CGLE-12-AEC1-P application, or MPM3807CGLE-12-AEC1-P equivalent, this module supports fast transient response via constant-on-time (COT) control, includes power-good signaling, thermal shutdown, short-circuit hiccup protection, and wettable-flank QFN-15 packaging for automated optical inspection in safety-critical automotive PCB assembly.

Technical Context

The MPM3807CGLE-12-AEC1-P implements a constant-on-time (COT) control architecture with VIN feed-forward, enabling stable 2.4MHz switching across its full 2.5V–5.5V input range and maintaining tight output regulation during rapid load transients. Its internal high-side P-channel and low-side N-channel MOSFETs feature 70mΩ and 40mΩ R_DS(ON), respectively, optimized for efficiency at 2A output.

It operates exclusively in forced continuous conduction mode (FCCM), eliminating mode transitions and ensuring consistent EMI profile. The fixed 1.2V output version disables the FB pin, integrates internal resistor divider, and uses OUT_S for controlled output discharge through a 150Ω internal path-critical for pre-biased start-up and rail sequencing in camera modules and radar sensors.

Key Specifications

Pinout & Package

MPM3807CGLE-12-AEC1-P is housed in a 15-pin QFN package (3mm × 4mm × 1.6mm) with exposed thermal pad and wettable flank sidewalls for solder fillet inspection. Pin 15 (DNC) is internally tied to SW and must remain unconnected.

FAQ

Is MPM3807CGLE-12-AEC1-P pin-compatible with other MPM3807C variants?

Yes - all MPM3807C variants (adjustable and fixed-output) share identical QFN-15 pinout and footprint. The fixed 1.2V version (this part) floats the FB pin and configures internal feedback; no layout change is needed when migrating from adjustable versions.

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 V_OUT collapse. It must be connected to the same net as OUT; leaving it floating disables discharge and risks unsafe residual voltage in safety-critical systems.

Does this module support pre-biased output startup?

Yes - the MPM3807CGLE-12-AEC1-P initiates regulation even when V_OUT is pre-charged to 1.2V, thanks to its internal soft-start controller and independent SS pin timing. This is verified per datasheet Section 18 (Operation).

How does the PG pin interface with a 3.3V microcontroller GPIO?

Connect a 10kΩ pull-up resistor from PG to 3.3V. PG asserts high (>2.4V) when V_OUT ≥ 1.08V and low (<0.4V) when ≤1.02V. The open-drain structure ensures logic-level compatibility without level-shifting circuitry.

What thermal derating applies at 85°C ambient temperature?

With standard 4-layer PCB (2oz copper, 65°C/W θ_JA), maximum continuous output current remains 2A up to +85°C ambient. At +105°C ambient, output current must be limited to ~1.6A to maintain T_J ≤ 150°C per thermal calculations in datasheet Section 6.

Can the SS pin be used to synchronize startup timing with other rails?

No - SS controls only the internal soft-start ramp rate via external capacitor; it does not accept external timing signals. For coordinated sequencing, use the EN pin with controlled voltage ramps or digital GPIO timing from a system PMIC.

Is the integrated inductor shielded, and what is its saturation current?

Yes - the integrated inductor is fully shielded and rated for 4.8A to 5.4A saturation current (min to max). This exceeds the 2A output requirement with >140% margin, preventing inductance collapse during peak transient loads in ADAS sensors.
