Product details
Overview
MPQ3413GJ-5-AEC1-P from Monolithic Power Systems is a synchronous step-up DC/DC converter IC designed for automotive secondary regulation and single-cell Li-ion battery backup systems. It delivers a fixed 5V output at up to 0.3A average current, operates from 2.8V–4V input, features true output disconnect, 2.2MHz switching frequency, and AEC-Q100 Grade 1 qualification for under-hood use.
For engineers reviewing the MPQ3413GJ-5-AEC1-P datasheet, MPQ3413GJ-5-AEC1-P pinout, MPQ3413GJ-5-AEC1-P application, or MPQ3413GJ-5-AEC1-P equivalent, key selection criteria include its <1μA shutdown current, integrated P-channel output disconnect MOSFET, 52μA quiescent current, and dual-mode operation (AAM/FCCM) with MODE pin control.
Technical Context
The MPQ3413GJ-5-AEC1-P uses fixed-frequency (2.2MHz), current-mode PWM control with internal slope compensation and an error amplifier comparing a 0.6V reference against feedback. Its architecture integrates both N-channel (70mΩ RDS(ON)) and P-channel (80mΩ RDS(ON)) power MOSFETs for synchronous boost and true output disconnect.
Startup begins in linear-charge mode using the P-channel MOSFET until VOUT ≈ VIN, then transitions to regulated boost switching with peak current limiting at 3.6A. Protection includes OVP (6V threshold), SCP (auto-recovery), and thermal shutdown (155°C trip, 130°C hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5V ±2.5% over -40°C to +125°C; enables direct USB-5V rail generation from low-voltage batteries. |
| Input voltage range | 2.8V to 4V; supports single-cell Li-ion (2.8V cutoff) and automotive 3.3V auxiliary rails without external LDO pre-regulation. |
| Switching frequency | 2.2MHz ±14%; allows use of sub-1μH inductors (e.g., 0.68μH) and reduces EMI fundamental while enabling compact layout. |
| Quiescent current | 52μA at VIN = 3.3V, no load; ensures minimal battery drain during vehicle sleep modes. |
| Shutdown current | <1μA; achieved via complete output disconnect and internal bias sourcing from VOUT when VOUT > VIN. |
| Peak switch current | 3.6A typical; supports transient loads beyond steady-state 0.3A average, critical for camera flash or sensor burst operation. |
| Efficiency | Up to 85% at 0.3A/3.3VIN; enabled by synchronous rectification and low RDS(ON) MOSFETs, reducing thermal stress in TSOT23-8 package. |
Pinout & Package
MPQ3413GJ-5-AEC1-P is housed in a thermally enhanced TSOT23-8 package (2.9mm × 1.6mm × 0.85mm), optimized for high-power density in automotive PCBs with exposed PGND pad for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power input supply | Bias source during startup; must be locally bypassed with ≥10μF ceramic capacitor to limit VIN ripple and inrush. |
| 2 OUT | Regulated output node | Drain of internal P-channel disconnect MOSFET; connects to output filter (≥22μF); serves as regulation sensing point. |
| 3 SW | Switch node | Connection between internal N- and P-channel MOSFETs; requires short/wide trace to inductor to minimize EMI and voltage spikes. |
| 4 PGND | Power ground return | Main current return path for inductor and MOSFETs; must tie directly to large copper pour and thermal vias for θJA = 100°C/W. |
| 5 FTY | Factory test only | No user connection required; floating or grounded per board design-no functional impact on operation. |
| 6 AGND | Analog ground reference | Reference for error amplifier and feedback circuitry; must be isolated from noisy PGND and tied at single point near FB divider. |
| 7 MODE | Operating mode select | Logic-high enables AAM (frequency stretching for light-load efficiency); logic-low forces FCCM (constant 2.2MHz for low-noise EMI). |
| 8 EN | Enable control input | Active-high enable: >1.2V turns on regulator; <0.4V initiates full shutdown with output disconnect and <1μA draw. |
Key Features
| Feature | Design Value |
|---|---|
| True output disconnect | Internal P-channel MOSFET fully isolates OUT from IN during shutdown, enabling zero-output residual voltage and eliminating need for external diode. |
| Integrated soft start | Internal capacitor-based ramp limits inrush current during startup, preventing input voltage sag and system brownout in battery-powered applications. |
| Dual modulation modes | AAM extends light-load efficiency via frequency reduction; FCCM maintains constant switching for predictable EMI filtering and stable loop response. |
| Comprehensive protection suite | OVP (6V), SCP (auto-recover), OTP (155°C/130°C hysteresis), and UVLO (1.7V) ensure robust operation in harsh automotive environments. |
| Automotive-grade reliability | AEC-Q100 Grade 1 qualified (-40°C to +125°C TJ), halogen-free, RoHS-compliant, and qualified for under-hood deployment per ISO 16750. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610995RTER | Fixed 5V output, 1.2MHz fSW, 300nA shutdown current, but no output disconnect MOSFET; requires external diode. | Lacks true output disconnect; unsuitable for systems requiring zero-VOUT during shutdown or reverse-current blocking. | Select only if ultra-low shutdown current outweighs need for output isolation and board space permits external Schottky diode. |
| MAX17222ATA+T | 5V output, 2MHz fSW, 300nA ISD, integrated disconnect, but rated only for industrial (-40°C to +85°C), not AEC-Q100. | Not qualified for automotive temperature or reliability stress testing; limited to cabin/non-critical modules. | Acceptable for infotainment accessories outside engine bay; reject for powertrain, ADAS, or BCM deployments requiring Grade 1 compliance. |
Compared with TPS610995RTER and MAX17222ATA+T, MPQ3413GJ-5-AEC1-P uniquely combines AEC-Q100 Grade 1, true output disconnect, and 2.2MHz operation in TSOT23-8-enabling smaller magnetics, lower thermal resistance, and guaranteed automotive reliability without external components.

FAQ
What is the maximum continuous output current supported by MPQ3413GJ-5-AEC1-P?
The MPQ3413GJ-5-AEC1-P supports 0.3A average output current continuously under typical conditions (VIN = 3.3V, TA = 25°C, 22μF COUT). Peak switch current capability is 3.6A, enabling brief transients beyond 0.3A, but sustained operation above 0.3A requires careful thermal design due to TSOT23-8 power dissipation limits (1.25W max at 25°C ambient).
Can MPQ3413GJ-5-AEC1-P operate with input voltage higher than 4V?
No. The absolute maximum input voltage is 6.5V, but recommended operating VIN is strictly 2.8V to 4V. Operation above 4V violates the specified operating conditions and risks triggering minimum on-time limitation, excessive VOUT ripple, or instability-per datasheet Note 4. Input voltages exceeding 4V are not supported for reliable regulation.
How does the MODE pin affect efficiency and EMI performance?
When MODE is high, the device enters Advanced Asynchronous Modulation (AAM), reducing switching frequency under light loads to improve efficiency (e.g., >80% at 10mA). When MODE is low, Forced Continuous Conduction Mode (FCCM) maintains constant 2.2MHz operation, yielding predictable EMI spectra ideal for filtering but slightly lower light-load efficiency.
Is an external Schottky diode required with MPQ3413GJ-5-AEC1-P?
No. The MPQ3413GJ-5-AEC1-P integrates a synchronous rectifier and a dedicated P-channel disconnect MOSFET, eliminating the need for an external Schottky diode. Adding one would compromise the true output disconnect function and increase forward voltage drop, reducing efficiency and violating the recommended layout.
What is the purpose of the FTY pin, and how should it be connected?
The FTY pin is reserved for factory test and has no functional role in end-user applications. It may be left floating or connected to PGND-neither choice affects regulation, protection, or efficiency. No external components or routing are required for FTY in standard designs.
Does MPQ3413GJ-5-AEC1-P support adjustable output voltage?
No. MPQ3413GJ-5-AEC1-P is a fixed 5V output device. The "-5" in the part number denotes the 5V factory-trimmed reference. Output voltage cannot be adjusted via external resistors; alternative variants (e.g., MPQ3413GJ-33-AEC1-P) exist for other fixed outputs, but no resistor-divider feedback option is available.
How does the device behave during cold-crank conditions where VIN drops below 2.8V?
Below 2.8V, the device enters undervoltage lockout (UVLO) and shuts down. The UVLO turn-on threshold is 1.7V (typical) with 100mV hysteresis. During cold crank, if VIN falls below 1.65V, the MPQ3413GJ-5-AEC1-P ceases switching and draws <1μA, preventing erratic behavior or unregulated output-ensuring system safety during battery recovery.
