Product details
Overview
MPQ1923GR-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, high-frequency N-channel MOSFET half-bridge gate driver with 100V switching node rating, 8A sink/7A source peak output current, and <5ns propagation delay matching between high-side and low-side channels. It integrates a bootstrap diode, supports 120V BST voltage, and operates across -40°C to +125°C junction temperature for automotive motor drivers and telecom DC/DC converters.
For engineers reviewing the MPQ1923GR-AEC1-P datasheet, MPQ1923GR-AEC1-P pinout, MPQ1923GR-AEC1-P application, or MPQ1923GR-AEC1-P equivalent, key selection criteria include UVLO thresholds (4.5V falling), 7.2ns/5.5ns rise/fall times into 1nF load, TTL-compatible inputs, and QFN-8 (4mm×4mm) package with exposed thermal pad.
Technical Context
The MPQ1923GR-AEC1-P implements independent high-side and low-side driver channels with matched timing (<5ns delay skew) and separate under-voltage lockout (UVLO) on both VDD and BST–SW rails. Its integrated bootstrap diode eliminates external diode requirement while maintaining 120V BST voltage capability.
It features TTL-compatible INH/INL inputs with internal 155kΩ pull-downs, thermal shutdown at 165°C with 25°C hysteresis, and robust protection against shoot-through via precise dead-time control enabled by independent input logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VSW Rating | 100V max - supports half-bridge topologies with up to 100V bus voltage, including telecom and automotive DC/DC stages. |
| Peak Output Current | 8A sink / 7A source at 12V VDD - drives large gate capacitances rapidly, enabling fast MOSFET switching in high-power converters. |
| Propagation Delay Matching | <5ns - ensures precise timing alignment between HS and LS outputs, critical for minimizing dead-time uncertainty and preventing shoot-through. |
| Rise/Fall Time (1nF) | 7.2ns tRISE, 5.5ns tFALL - enables >10MHz effective switching frequency with minimal switching loss in high-frequency SMPS. |
| UVLO Thresholds | VDD falling: 4.5V; BST–SW falling: 3.2V - prevents erratic operation during brown-out or bootstrap capacitor discharge. |
| Bootstrap Diode | Integrated - reduces BOM count and PCB area; VF = 0.9V @ 100μA, 1.2V @ 100mA - minimizes forward drop impact on high-side drive efficiency. |
| Quiescent Current | 300μA max IDD_Q - enables low-power standby modes in always-on automotive systems without compromising startup reliability. |
Pinout & Package
MPQ1923GR-AEC1-P is housed in a thermally enhanced QFN-8 (4mm × 4mm) package with exposed pad for improved heat dissipation. The package complies with AEC-Q100 Grade 1 and JEDEC MO-220 standards, featuring 0.08mm max lead coplanarity and RoHS-compliant, halogen-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Primary supply rail | Provides power to internal logic and low-side driver; requires local 0.1μF decoupling to ground. |
| 2: BST | Bootstrap supply input | Connects to bootstrap capacitor; supplies floating high-side driver; rated to 120V relative to SW. |
| 3: DRVH | High-side gate driver output | Drives N-channel MOSFET gate referenced to SW node; capable of 8A sink/7A source. |
| 4: SW | Switching node connection | Connects to HS-FET source and LS-FET drain; must be routed with minimal inductance to suppress undershoot. |
| 5: DRVL | Low-side gate driver output | Drives N-channel MOSFET gate referenced to VSS; matches DRVH timing within 5ns. |
| 6: VSS | Digital and power ground | Common return for logic, drivers, and exposed pad; multiple vias to solid ground plane required. |
| 7: INL | Low-side enable input | TTL-compatible; internal 155kΩ pull-down ensures default-off state if left floating. |
| 8: INH | High-side enable input | TTL-compatible; independent control allows programmable dead-time insertion via controller. |
| Pad: Exposed Pad | Thermal and electrical ground | Must be soldered to VSS-connected copper pour; improves θJA by ~10°C/W and enhances reliability in automotive thermal cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Independent HS/LS control | Enables precise dead-time management in half-bridge, two-switch forward, and active-clamp topologies without external logic. |
| Integrated bootstrap diode | Eliminates discrete diode, reducing component count and layout sensitivity while maintaining 120V BST capability. |
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures from −40°C to +125°C, supporting engine bay and ADAS power stage applications. |
| Matched propagation delay | <5ns skew ensures consistent timing margins across temperature and voltage, simplifying controller dead-time calibration. |
| UVLO on both VDD and BST–SW | Prevents partial drive conditions that could cause shoot-through or MOSFET overstress during supply transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ1923GRE-AEC1 | QFN-10 (4mm×4mm) package with NC pins; identical electrical specs and AEC-Q100 Grade 1 rating. | Offers additional routing flexibility and thermal margin via extra pins and larger exposed pad area. | Select when board layout requires dedicated BST/VSS decoupling paths or higher thermal derating margin. |
| LM5109BMAX/NOPB | Non-AEC-Q100; 100V VSW, but only 2A peak output; no integrated bootstrap diode; 50ns typical propagation delay. | Limited to industrial/commercial DC/DC where automotive qualification and high-speed timing are not required. | Choose only for cost-sensitive non-automotive designs where 8A drive strength and <5ns matching are unnecessary. |
Compared with MPQ1923GRE-AEC1, the MPQ1923GR-AEC1-P offers identical performance in a smaller QFN-8 footprint-ideal for space-constrained automotive modules-while LM5109BMAX lacks AEC-Q100 validation, integrated bootstrap, and sub-5ns matching needed for high-reliability, high-frequency motor control.

FAQ
What is the maximum allowable VSW voltage for continuous operation?
The MPQ1923GR-AEC1-P supports continuous operation up to +100V on the SW pin, with transient tolerance to +120V for durations under 2µs. This rating enables use in 48V and 60V automotive systems and telecom intermediate bus applications without external clamping.
Does the device require an external bootstrap diode?
No. The MPQ1923GR-AEC1-P integrates a bootstrap diode with 0.9V forward voltage at 100μA and 1.2V at 100mA. This eliminates the need for an external diode, reducing BOM count and PCB area while maintaining full 120V BST voltage capability.
How is shoot-through prevented in this gate driver?
Shoot-through is mitigated through independent INH/INL inputs allowing precise dead-time control by the PWM controller, combined with matched <5ns propagation delays and dual UVLO protection on both VDD and BST–SW rails to force outputs low during undervoltage conditions.
What thermal management practices are recommended for automotive deployment?
For automotive use, solder the exposed pad directly to a VSS-connected thermal pad with ≥4 thermal vias, use a 2oz copper ground plane, and maintain ≥2mm clearance from adjacent heat sources. Thermal resistance is 47°C/W (θJA) on a 4-layer board per JESD51-7.
Can MPQ1923GR-AEC1-P drive SiC or GaN MOSFETs?
Yes. Its 7.2ns/5.5ns rise/fall times into 1nF, 8A peak current, and 100V VSW rating support fast-switching wide-bandgap devices. However, layout must minimize SW node inductance and gate loop area to avoid ringing and EMI in high-dv/dt applications.
Is there a difference between MPQ1923GR-AEC1 and MPQ1923GR-AEC1-P?
MPQ1923GR-AEC1-P denotes the tape-and-reel packaged version (suffix -P indicates packaging variant per MPS ordering conventions), while MPQ1923GR-AEC1 refers to the base part number. Electrical, thermal, and functional specifications are identical.
What is the minimum input pulse width supported for reliable output switching?
The MPQ1923GR-AEC1-P guarantees reliable output toggling with input pulse widths ≥50ns, verified by design across temperature and voltage ranges. This enables stable operation in PWM controllers running above 10MHz effective frequency.
