Product details
Overview
MPQ4488TGU-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–2.2MHz), and 135°C load-shedding thermal protection. It delivers 5.1V/5.17V/5.3V output with ±2% accuracy, supports BC1.2 DCP, USB Type-C 5V@3A DFP, and operates across automotive-grade -40°C to +125°C junction temperature.
For engineers reviewing the MPQ4488TGU-AEC1-P datasheet, MPQ4488TGU-AEC1-P pinout, MPQ4488TGU-AEC1-P application, or MPQ4488TGU-AEC1-P equivalent, this device serves as a complete USB charging power solution for automotive infotainment head units, telematics control units (TCUs), and rear-seat entertainment systems requiring dual-port compliance, spread-spectrum EMI reduction, and robust over-voltage/over-current protection.
Technical Context
The MPQ4488TGU-AEC1-P integrates a fixed-frequency peak-current-mode buck controller with internal 18mΩ/15mΩ HS/LS MOSFETs, two independent 13mΩ USB power switches, and full Type-C CC logic (CC1/CC2/CC3/CC4) supporting VCONN sourcing. Its forced CCM operation ensures stable 450kHz default switching (adjustable via FREQ pin) and eliminates light-load mode transitions that compromise ripple or EMI predictability.
It implements autonomous port identification-supporting BC1.2 DCP, divider mode, 1.2V/1.2V handshake, and USB Type-C 5V@3A DFP-without external microcontroller intervention. The 90mV line-drop compensation maintains output voltage accuracy under high-current cable losses, while hiccup-mode OCP protects both buck and USB outputs during sustained overloads.

Pinout & Package
MPQ4488TGU-AEC1-P is housed in a thermally enhanced QFN-26 (5mm × 5mm, 0.5mm pitch) package with exposed thermal pad. Pin numbering follows standard JEDEC top-view orientation; PGND pins (1,5,13,20,21) and SW pins (8,9,26) are distributed to minimize loop inductance and thermal resistance (θJA = 20°C/W on 4-layer PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 13, 20, 21 | PGND | Power ground return path for buck switch node and USB switches; requires low-impedance copper pour and multiple vias to thermal pad. |
| 2, 16 | USB1 / USB2 | Current-limited 3A output terminals; integrate internal 13mΩ MOSFETs and OVP clamping diodes. |
| 3, 15, 25 | OUT | Buck output node supplying power to both USB ports; connects to bulk output capacitor (270µF typical). |
| 4, 14 | IN | Main input supply (6–36V); feeds internal HS-FET drain and bootstrap circuit; requires ≥30µF local ceramic+bulk capacitance. |
| 6 | AGND | Analog reference ground for error amplifier and sensing circuits; must be star-connected to PGND at single point. |
| 7 | VCC | 4.5V internal LDO output; powers control logic; requires 1µF ceramic decoupling adjacent to pin. |
| 8, 9, 26 | SW | Switch node connecting internal HS/LS MOSFETs; drives external inductor; high dV/dt demands short, wide trace routing. |
| 10 | BST | Bootstrap capacitor connection (0.22µF) for floating gate driver; critical for HS-FET turn-on reliability. |
| 11 | OUT_SEL | Three-state voltage select: low = 5.1V, float = 5.17V, high = 5.3V; sets USB output compliance level. |
| 12 | FREQ | Frequency programming input; resistor-to-GND sets frequency; float/VCC enables 450kHz default or spread spectrum. |
| 22, 23 | DP1 / DM1 | USB1 data lines for BC1.2/Type-C handshaking; include internal 1.2V/1.2V mode drivers and 14kΩ impedance. |
| 19, 20 | DM2 / DP2 | USB2 data lines with identical functionality to DP1/DM1; enable independent port negotiation. |
| 17, 18, 24 | CC4 / CC3 / CC2 | Type-C configuration channel inputs; detect plug orientation, source/sink role, and enable VCONN power delivery. |
| 1 | CC1 | Primary Type-C CC input; used with CC2 for dual-role detection and VCONN assignment per USB PD spec. |
| 21 | EN | Enable control with 8µA internal pull-up; logic-high >1.235V enables operation; clamped to 7.6V for overvoltage safety. |
Key Features
| Feature | Design Value |
|---|---|
| Dual USB port integration | Eliminates need for two discrete USB switches and port ID ICs - reduces BOM count by ≥5 components and PCB area by 30%. |
| Programmable output voltage | Three factory-trimmed options (5.1V/5.17V/5.3V) via single OUT_SEL pin - avoids external resistor dividers and improves production test efficiency. |
| 90mV line-drop compensation | Actively adjusts output voltage based on load current to maintain ±1% regulation at connector - critical for long USB cables in automotive cabins. |
| 135°C load shedding | Reduces output current before thermal shutdown triggers - sustains partial functionality (e.g., one USB port active) during prolonged high-temp operation. |
| ±8kV HBM ESD on USB/CC pins | Meets AEC-Q100 stress requirements without external TVS diodes - lowers system-level ESD design risk and validation cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-USB automotive power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4488B | Successor with improved thermal performance (150°C shutdown), lower RDS(ON) (15mΩ/12mΩ), and updated spread-spectrum algorithm. | Supports same USB protocols but adds USB PD 3.0 sink capability and enhanced ESD (±10kV HBM on CC pins). | Select MPQ4488B for new designs requiring extended lifetime, higher efficiency at 125°C, or future-proofing for USB PD upgrades. |
| TPS65987D | TI USB PD controller with integrated buck; supports full USB PD 3.0 (20V/5A), but lacks native BC1.2/Type-C DFP auto-detection. | Requires external USB switch and firmware coordination for legacy charging modes - increases BOM and software complexity. | Choose only if USB PD 20V output or dual-role port (DRP) functionality is mandatory; not drop-in compatible. |
Compared with MPQ4488B, the MPQ4488TGU-AEC1-P offers identical pinout and feature set but with higher thermal trip thresholds and less aggressive spread-spectrum modulation - making it suitable for legacy qualification continuity, while TPS65987D introduces protocol flexibility at the cost of design simplicity and AEC-Q100 alignment.

FAQ
Is MPQ4488TGU-AEC1-P recommended for new designs?
No. Monolithic Power Systems explicitly states "NOT RECOMMENDED FOR NEW DESIGNS, REFER TO MPQ4488B" in the datasheet revision 1.1. The MPQ4488B supersedes this part with improved thermal specs, lower RDS(ON), and updated spread-spectrum behavior. MPQ4488TGU-AEC1-P remains available for existing production and qualification continuity only.
What is the function of the OUT_SEL pin, and how do I configure it?
OUT_SEL selects the buck output voltage: logic low = 5.10V, floating = 5.17V (default), logic high = 5.30V. It is a three-state digital input - no external resistor needed. Floating is achieved by leaving the pin unconnected; pull-up/pull-down resistors ≥100kΩ ensure reliable logic levels without loading the internal reference.
Does MPQ4488TGU-AEC1-P support USB Power Delivery (PD)?
No. It supports USB Type-C 5V @ 3A DFP (Downstream Facing Port) mode only - meaning it acts as a fixed 5V source with CC-based detection and VCONN power, but does not negotiate variable voltages (9V/15V/20V) or implement USB PD communication protocol. For PD, consider MPQ4488B or dedicated PD controllers.
How does the 135°C load-shedding feature operate?
At 135°C junction temperature, the IC reduces output current by lowering the current-limit threshold - preventing immediate thermal shutdown at 165°C. This allows continued partial operation (e.g., one USB port active) during sustained high-temp conditions, improving system resilience without firmware intervention.
Can I use MPQ4488TGU-AEC1-P without spread-spectrum functionality?
Yes. Spread spectrum is only enabled on FD/FD2 variants (MPQ4488TGU-FD-AEC1/MPQ4488TGU-FD2-AEC1) when FREQ is floated or tied to VCC. The MPQ4488TGU-AEC1-P variant has no spread-spectrum capability - FREQ pin functions solely as a frequency programming input with resistor-to-GND or direct GND connection.
What is the minimum off-time specification, and why does it matter?
The minimum off-time is 110ns. At high switching frequencies (e.g., 2.2MHz), this limits achievable duty cycle - especially at low input voltages - and constrains maximum output current due to reduced conduction time for the low-side MOSFET. Designers must verify tOFF(MIN) margin using worst-case VIN and VOUT.
Are the USB data lines (DP1/DM1/DP2/DM2) ESD-protected internally?
Yes. All DP/DM pins have ±8kV HBM ESD rating per JEDEC JESD22-A114, verified per AEC-Q100-002. No external ESD protection diodes are required for basic compliance, though system-level testing may still warrant board-level TVS for extreme environments.
