Product details
Overview
MPQ4210GU-AEC1-Z from Monolithic Power Systems is a synchronous four-switch buck-boost controller qualified to AEC-Q100 Grade 1 (−40°C to +125°C), supporting 6V–40V startup and 5V–40V operation, with I²C-programmable 0.5V–28V output voltage, 200kHz–600kHz selectable switching frequency, and integrated current monitor (IMON) for USB PD power supplies.
For engineers reviewing the MPQ4210GU-AEC1-Z datasheet, MPQ4210GU-AEC1-Z pinout, MPQ4210GU-AEC1-Z application, or MPQ4210GU-AEC1-Z equivalent, key selection considerations include its valley/peak current control architecture for smooth buck-boost transitions, programmable average current limit (39–76 mV sense range), forced CCM mode, and wettable-flank QFN-27 (5mm×5mm) package for automotive-grade solder joint inspection.
Technical Context
The MPQ4210GU-AEC1-Z implements dual-mode current sensing: valley current control in buck mode and peak current control in boost mode, enabling fast load transient response (<1ms recovery) and seamless mode transition without output voltage dip. Its I²C interface supports real-time VOUT slew-rate control (25–170 mV/ms), reference voltage programming (0.5V–2.047V), and constant-current limit configuration.
It integrates independent protection logic including programmable OVP (119–135% VREF trip), OCP (60% VREF hiccup threshold), VIN UVLO hysteresis, thermal shutdown at 150°C with 25°C hysteresis, and interrupt reporting via open-drain INT pin for PNG, OCP, OVP, and OTP events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck-boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5175RHFTR | No integrated I²C interface; uses resistor-programmed VOUT and fixed 200kHz–2.2MHz frequency; no IMON output. | Suitable for cost-sensitive industrial SMPS where digital control is unnecessary; lacks USB PD profile support. | Select when firmware-controlled voltage ramping, current telemetry, or multi-profile output is not required. |
| TPS630702RTER | Lower 1.8V–16V input range; max 5A output; no AEC-Q100 qualification; no programmable OCP/OVP thresholds. | Targeted at portable electronics and non-automotive embedded systems; insufficient for 24V battery input or automotive temp range. | Choose only for consumer-grade 5V/3.3V point-of-load applications with ≤16V input and no functional safety requirements. |

FAQ
What is the minimum startup voltage for MPQ4210GU-AEC1-Z?
The MPQ4210GU-AEC1-Z requires a minimum 6V on VIN to initiate startup, verified across −40°C to +125°C. Below this, internal bias circuits remain unpowered and the device stays in shutdown regardless of EN state. This threshold is fixed and not programmable.
How does the I²C interface configure output voltage slew rate?
The slew rate is controlled via two I²C bits (SR[1:0]) selecting one of four fixed rates: 25–51 mV/ms (SR=00), 130–170 mV/ms (SR=11), or two intermediate values. This directly modulates the DAC settling speed driving the error amplifier reference, limiting dVOUT/dt during voltage transitions.
Can MPQ4210GU-AEC1-Z operate in discontinuous conduction mode (DCM)?
No-MPQ4210GU-AEC1-Z operates exclusively in forced continuous conduction mode (FCCM). It maintains constant switching frequency and inductor current flow even at light loads, eliminating DCM-related output ripple and audible noise common in automotive audio and display subsystems.
What is the purpose of the IAVGP and IAVGN pins?
IAVGP and IAVGN accept a differential voltage across an external output shunt resistor to set the average output current limit. The IC compares this voltage against internal thresholds (39–76 mV range) and triggers hiccup-mode OCP if exceeded-enabling precise constant-current regulation for supercapacitor charging or battery backup.
Does MPQ4210GU-AEC1-Z support automatic VIN-to-VOUT power path selection?
Yes-the device autonomously selects power source based on internal logic: when VOUT ≥5V and VCC load <10mA, VCC is powered from VOUT; otherwise, VCC draws from VIN. This ensures stable gate drive during input brownouts and output regulation transitions without external circuitry.
How is thermal protection implemented?
Thermal shutdown activates at 150°C junction temperature with 25°C hysteresis. Upon trip, switching halts, IMON and INT are deasserted, and the device remains latched off until die temperature falls below 125°C. No external components are needed for this protection.
Is the QFN-27 package lead-free and RoHS compliant?
Yes-MPQ4210GU-AEC1-Z uses lead-free, halogen-free packaging and fully complies with EU RoHS Directive 2011/65/EU. MPS confirms green status on its official quality assurance portal, with full material declarations available upon request.
