Product details
Overview
MPQ2286GLE-0000-AEC1-Z from Monolithic Power Systems is a programmable, AEC-Q100 Grade 1 qualified synchronous buck regulator with integrated 6mΩ high-side and 4mΩ low-side MOSFETs, delivering up to 12A output current from a 2.7V–6V input. It features zero-delay PWM (ZDP™) control, configurable 2–4MHz switching frequency, differential VOUT sensing, and digital I²C interface with OTP memory for automotive point-of-load applications including ADAS and SoC core rails.
For engineers reviewing the MPQ2286GLE-0000-AEC1-Z datasheet, MPQ2286GLE-0000-AEC1-Z pinout, MPQ2286GLE-0000-AEC1-Z application, or MPQ2286GLE-0000-AEC1-Z equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 1.0% output regulation accuracy, thermal warning/over-temperature shutdown thresholds, spread-spectrum EMI reduction, and factory-programmable OTP configuration for VOUT, slew rate, and protection settings.
Technical Context
The MPQ2286 operates in forced continuous conduction mode (FCCM) or discontinuous conduction mode (DCM), with ZDP™ architecture enabling ultra-fast transient response via real-time duty-cycle adjustment without loop compensation delay. Its digital interface supports register-level control of output voltage (0.20625V–3.6V), startup/shutdown slew rates (1.25–10 mV/µs), and fault reporting with packet error checking (PEC).
Internal protections include peak/valley current limiting (18–27A HS / 12–18A LS), input/output overvoltage (VIN_OV = 6.5–6.85V, VOUT_OV = 113–119%), thermal warning (125–155°C), and over-temperature shutdown (155–185°C), all configurable via OTP. The QFN-18 (3mm×4mm) package with wettable flanks supports automated optical inspection and high-reliability automotive assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62933RGER | 3.6V–16V input, 3A output, no integrated OTP or differential sensing; uses external resistor divider for VOUT setting. | Targeted at non-automotive industrial PoL; lacks AEC-Q100 qualification and ZDP™ transient response. | Select only for cost-sensitive non-automotive designs where 12A output and automotive qualification are not required. |
| RTQ2132BGQW | 2.7V–6V input, 12A output, AEC-Q100 Grade 1, but uses analog PMW control (no digital interface) and fixed 2.2MHz fSW. | Suitable for ADAS camera modules needing robustness but no runtime reconfiguration or telemetry. | Choose when digital configurability and I²C telemetry are unnecessary, and fixed-frequency EMI profile is preferred over spread-spectrum. |

FAQ
What AEC-Q100 qualification level does MPQ2286GLE-0000-AEC1-Z meet?
The MPQ2286GLE-0000-AEC1-Z is qualified to AEC-Q100 Grade 1, meaning it is specified for operation from −40°C to +125°C ambient temperature and has passed stress tests including HTOL, TC, UHAST, and ESD per AEC-Q100 Rev H. This qualifies it for under-hood and cockpit module deployment without derating.
How is output voltage configured on this device?
VOUT is digitally programmed via the I²C interface using OTP memory registers, supporting a range from 0.20625V to 3.6V in 6.25mV steps. The VOUT_SCALE bit selects between 1× (for 0.206–1.8V) and 2× (for 1.8–3.6V) scaling to maintain resolution and accuracy across the full range.
Does MPQ2286GLE-0000-AEC1-Z support forced continuous conduction mode (FCCM)?
Yes-FCCM can be enabled either by applying an external clock signal to SYNCIN or by writing to the MODE register via I²C. In FCCM, the regulator maintains constant switching frequency (2–4MHz) regardless of load, improving ripple performance and simplifying EMI filter design.
What thermal protection features are implemented?
The device integrates two independent thermal thresholds: a programmable thermal warning (TTW = 125–155°C) that asserts a flag for system throttling, and a hard over-temperature shutdown (TTSD = 155–185°C) with 20°C hysteresis. Both thresholds are stored in OTP and can be calibrated per unit during test.
Can the MPQ2286GLE-0000-AEC1-Z be used without the digital interface?
Yes-the device operates in default analog mode with factory-programmed OTP settings. SDA and SCL pins may be tied to GND if unused, and all critical functions (enable, power good, sync) remain fully operational without I²C communication.
What is the purpose of the VOUT+ and VOUT− pins?
VOUT+ and VOUT− provide Kelvin (4-wire) differential sensing at the load, rejecting voltage drop across PCB traces and connectors. This enables ±1% output regulation accuracy even with 50mΩ total path resistance-essential for low-voltage, high-current SoC rails.
Is spread-spectrum modulation enabled by default?
Yes-spread-spectrum modulation is factory-enabled in OTP with ±7.5% frequency deviation at 9kHz. It can be disabled or adjusted via I²C register write, allowing designers to optimize EMI performance versus potential beat-frequency concerns in sensitive RF environments.
