Product details
Overview
MPQ4488TGU-FD2-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, monolithic 36V, 6A synchronous step-down converter with integrated dual USB charging ports (USB1/USB2), programmable switching frequency (250kHz base), ±10% spread spectrum modulation, and 135°C load-shedding thermal management. It delivers 5.17V output with 90mV line-drop compensation and supports BC1.2 DCP, 1.2V/1.2V, divider, and USB Type-C 5V@3A DFP modes for automotive infotainment and telematics power systems.
For engineers reviewing the MPQ4488TGU-FD2-AEC1-P datasheet, MPQ4488TGU-FD2-AEC1-P pinout, MPQ4488TGU-FD2-AEC1-P application, or MPQ4488TGU-FD2-AEC1-P equivalent, key selection criteria include its AEC-Q100 qualification, dual-USB port identification logic, 250kHz spread-spectrum base frequency, QFN-26 (5mm×5mm) package thermal performance, and load-shedding behavior at 135°C - all critical for automotive USB charging subsystems requiring EMI compliance and thermal robustness.
Technical Context
The MPQ4488TGU-FD2-AEC1-P integrates a fixed-frequency peak-current-mode buck controller with internal 18mΩ/15mΩ HS/LS MOSFETs and two independent 13mΩ USB power switches. Its FREQ pin enables either fixed-frequency operation (via resistor-to-GND) or ±10% triangular spread spectrum centered at 250kHz when floated or tied to VCC - directly reducing conducted EMI in automotive 12V rail applications.
It implements forced CCM operation across full load range, eliminating mode transitions that cause output ripple variation, while supporting three output voltages (5.1V/5.17V/5.3V) via OUT_SEL pin logic and full USB port auto-detection (BC1.2, Type-C DFP, 1.2V/1.2V, divider) without external firmware or host intervention.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 13, 20, 21 | PGND | Power ground return for buck switch node and USB outputs - requires low-impedance copper pour and multiple vias to thermal pad. |
| 2, 16 | USB1 / USB2 | Current-limited 3A USB power outputs - internally regulated to 5.17V with OVP clamp at 5.6V and hiccup protection. |
| 3, 15, 25 | OUT | Buck output node - supplies power to both USB ports and requires ≥270µF bulk capacitance for transient response. |
| 4, 14 | IN | Main 6–36V input - connects to automotive battery rail with ≥50µF local ceramic+electrolytic filtering. |
| 6 | AGND | Analog reference ground - must be star-connected to PGND near IC to avoid noise coupling into feedback and USB detection circuits. |
| 7 | VCC | 4.5V internal LDO output - powers control logic; requires 1µF ceramic decoupling adjacent to pin. |
| 8, 9, 26 | SW | Buck switch node - drives external 4.7µH inductor; demands wide copper trace and tight loop with BST/PGND. |
| 10 | BST | Bootstrap supply for HS gate driver - requires 220nF X7R ceramic capacitor between SW and BST. |
| 11 | OUT_SEL | Output voltage select - low = 5.1V, float = 5.17V, high = 5.3V; sets USB port compliance voltage per BC1.2/Type-C spec. |
| 12 | FREQ | Frequency programming - float/VCC enables 250kHz ±10% spread spectrum; GND/resistor sets fixed frequency (250–2200kHz). |
| 17, 18, 24 | CC4 / CC3 / CC2 | Type-C configuration channel inputs - detect plug orientation, enable VCONN, and configure DFP role per USB PD spec. |
| 19, 23 | DM2 / DM1 | USB 2.0 data lines - support BC1.2 handshaking (divider, 1.2V/1.2V) and Type-C detection without host CPU involvement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-USB automotive power delivery applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4488B | Successor with improved efficiency, lower quiescent current (200μA vs. 300μA), and updated spread-spectrum algorithm. | Same pinout and feature set but optimized for new designs targeting extended battery runtime in always-on modules. | Select MPQ4488B for new designs requiring lower IQ and higher light-load efficiency; MPQ4488TGU-FD2-AEC1-P remains valid for legacy qualification reuse. |
| TPS65987D | USB-C PD controller with integrated 3.3V/1.8V LDOs, no buck converter - requires external 5V source. | Supports full USB PD 3.0 negotiation (up to 100W), but lacks native 6A buck and BC1.2 compatibility. | Choose TPS65987D only when USB PD 3.0 bidirectional power and data roles are mandatory; not a functional replacement for MPQ4488TGU-FD2-AEC1-P's integrated buck+USB-A/C solution. |
Compared with MPQ4488B, the MPQ4488TGU-FD2-AEC1-P offers proven AEC-Q100 qualification for existing platforms but lacks the newer part's light-load efficiency and thermal performance; versus TPS65987D, it delivers self-contained 6A buck regulation and BC1.2 support without external 5V sourcing - making it uniquely suited for cost-sensitive, non-PD automotive USB charging.

FAQ
What does "FD2" signify in MPQ4488TGU-FD2-AEC1-P?
The "FD2" suffix identifies this variant as the version with 250kHz fundamental switching frequency and ±10% spread spectrum modulation enabled when the FREQ pin is floated or tied to VCC. It distinguishes it from FD (450kHz base) and non-FD (no spread spectrum) variants, ensuring correct EMI profile selection for automotive EMC testing.
Is MPQ4488TGU-FD2-AEC1-P still recommended for new designs?
No - Monolithic Power Systems explicitly states "NOT RECOMMENDED FOR NEW DESIGNS, REFER TO MPQ4488B" in the datasheet. MPQ4488TGU-FD2-AEC1-P remains fully qualified and supported for existing production, but MPQ4488B offers improved efficiency, lower quiescent current, and updated spread-spectrum behavior for new projects.
How does the 135°C load-shedding behavior differ from thermal shutdown?
At 135°C junction temperature, the MPQ4488TGU-FD2-AEC1-P initiates gradual current derating - reducing USB output current while maintaining regulation - rather than triggering immediate thermal shutdown at 165°C. This preserves partial functionality (e.g., one USB port active) during sustained high-temp operation, improving system resilience.
Can MPQ4488TGU-FD2-AEC1-P support USB Power Delivery (PD) protocols?
No - it supports USB Type-C 5V@3A DFP mode and BC1.2 charging standards, but lacks USB PD 2.0/3.0 protocol negotiation, variable voltage (9V/15V/20V), or communication over CC lines beyond basic detection. For full PD compliance, a dedicated PD controller like TPS65987D is required.
What is the minimum recommended input capacitance for stable operation?
A minimum of 50µF total input capacitance is recommended - comprising a 10µF X7R ceramic capacitor placed within 3mm of the IN and PGND pins, plus a 47µF low-ESR electrolytic or polymer capacitor nearby. This combination suppresses high-frequency switching noise and handles load-dump transients per ISO 7637-2.
Does the device require external compensation components for the buck loop?
No - the MPQ4488TGU-FD2-AEC1-P features an internally compensated error amplifier with optimized network, eliminating the need for external compensation components. Only standard input/output capacitors, inductor, BST capacitor, and optional FREQ resistor are required for full operation.
How is USB port identification performed without a host processor?
Port identification is executed entirely in hardware: BC1.2 DCP detection uses internal comparators on DP/DM lines; divider and 1.2V/1.2V modes rely on precision internal voltage references and current sources; Type-C DFP mode uses CC1/CC2/CC3/CC4 sensing with built-in VCONN control logic - all independent of firmware or host interaction.
