Product details
Overview
UCC27201AQDDARQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive half-bridge gate driver for N-channel MOSFETs, featuring independent HI/LI inputs, 120V max boot voltage, 3A source/sink output current, and 22ns typical propagation delay. It enables high-frequency switching in traction inverters and on-board chargers operating from –40°C to +150°C junction temperature.
For engineers reviewing the UCC27201AQDDARQ1 datasheet, UCC27201AQDDARQ1 pinout, UCC27201AQDDARQ1 application, or UCC27201AQDDARQ1 equivalent, this page delivers verified technical context, precise pin functions, real-world timing performance under load, UVLO thresholds per rail, and validated automotive-grade alternatives - all grounded in TI's SLUSC72C production data sheet (Rev. July 2024).
Technical Context
The UCC27201AQDDARQ1 integrates a level-shift circuit enabling high-side drive referenced to the HS node, with matched 1ns delay between HO and LO edges. Its internal bootstrap diode (0.65V VF, 0.65Ω RD) eliminates external diodes while supporting up to 120V HB–HS differential voltage.
It implements dual independent UVLO: VDD rising threshold at 7.1V (0.5V hysteresis) disables both drivers; VHB–HS rising threshold at 6.7V (0.4V hysteresis) disables only the high-side driver. Inputs are TTL-compatible with 2.3V/1.6V thresholds and 68kΩ pulldown resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Operating Range | 8–17 V - supports 12V bias rails common in automotive DC/DC and EPS systems |
| Max Boot Voltage (HB–HS) | 120 V - enables use in 100V-class traction and OBC half-bridges without external clamping |
| Output Current | ±3 A - drives high-Qg Si and SiC MOSFETs with fast turn-on/turn-off under 1000pF load |
| Rise/Fall Time (1000pF) | 8 ns / 7 ns - ensures <50 ns total edge transition for >1 MHz switching in wireless charging |
| Propagation Delay | 22 ns typ - maintains PWM fidelity at 500 kHz+ switching frequencies in OBC and EPS |
| UVLO Thresholds | VDD: 7.1 V (0.5 V hysteresis); VHB–HS: 6.7 V (0.4 V hysteresis) - prevents erratic switching during cold-crank or brownout |
| HS Negative Voltage Rating | –18 V (repetitive pulse) - withstands shoot-through-induced negative transients in noisy motor drive environments |
Pinout & Package
UCC27201AQDDARQ1 uses the DDA package: 8-pin PowerPAD™ SOIC-8 (4.9 mm × 3.9 mm body), with exposed thermal pad electrically tied to VSS and requiring PCB thermal plane connection for RθJB = 20°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Low-side power supply input | Supplies low-side driver and logic; decoupled to VSS with 0.22–1.0 μF capacitor |
| 2 HB | High-side bootstrap supply node | Connects to positive terminal of external bootstrap capacitor; internal diode anode ties to VDD |
| 3 HO | High-side gate output | Drives high-side MOSFET gate; referenced to HS pin, not VSS |
| 4 HS | High-side source reference | Connects to source of high-side MOSFET and negative terminal of bootstrap capacitor |
| 5 HI | High-side input | TTL-compatible control signal; 2.3V rising threshold enables direct MCU interface |
| 6 LI | Low-side input | Independent TTL input; allows asymmetric PWM or dead-time insertion via controller |
| 7 VSS | Ground reference | Common return for low-side driver, logic, and thermal pad; must be low-impedance |
| 8 LO | Low-side gate output | Drives low-side MOSFET gate; referenced to VSS |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.65V forward voltage and 0.65Ω dynamic resistance eliminate external diode, reducing BOM count and layout area |
| 1 ns delay matching | Ensures simultaneous HO/LO edge transitions within 1 ns, minimizing shoot-through risk in high-side/low-side configurations |
| AEC-Q100 Grade 1 | Qualified for –40°C to +150°C operation - meets automotive powertrain and safety-critical system requirements |
| –18 V HS transient tolerance | Withstands negative voltage spikes on HS pin during fast switching, improving robustness in traction inverters |
| Independent HI/LI inputs | Enables flexible control schemes including complementary, phase-shifted, or asymmetric PWM without external logic |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27211AQDDARQ1 | Same pinout and specs, but adds enable pin (EN) and higher 4A output current; identical thermal design and AEC-Q100 Grade 1 rating | Required where system-level enable/disable sequencing or higher gate charge delivery (>3A) is needed for large SiC modules | Select UCC27211AQDDARQ1 when EN functionality or extra current headroom justifies minor cost increase |

FAQ
What is the maximum allowable voltage on the HS pin of the UCC27201AQDDARQ1?
The UCC27201AQDDARQ1 supports a maximum repetitive HS pin voltage of –15 V to +110 V under recommended operating conditions, and absolute maximum ratings allow –18 V to +120 V for short pulses (<100 ns). This capability enables reliable operation during shoot-through events and fast-switching transients in traction inverters, where the UCC27201AQDDARQ1's –18 V tolerance eliminates need for external clamping diodes in most designs.
Does the UCC27201AQDDARQ1 require an external bootstrap diode?
No, the UCC27201AQDDARQ1 integrates an on-chip bootstrap diode with 0.65 V forward voltage and 0.65 Ω dynamic resistance. This eliminates the need for an external discrete diode, reducing bill-of-materials count, PCB area, and potential failure points. The internal diode connects VDD (anode) to HB (cathode), and the external bootstrap capacitor remains required between HB and HS pins per the UCC27201AQDDARQ1 application guidelines.
What are the UVLO thresholds for VDD and HB–HS on the UCC27201AQDDARQ1?
The UCC27201AQDDARQ1 features dual independent UVLO: VDD rising threshold is 7.1 V with 0.5 V hysteresis, disabling both drivers below this level; VHB–HS rising threshold is 6.7 V with 0.4 V hysteresis, disabling only the high-side driver. These thresholds ensure safe shutdown during cold-crank (e.g., 6.5 V battery) or bootstrap capacitor discharge, preventing partial drive that could cause shoot-through - a critical safeguard in automotive EPS and OBC systems using the UCC27201AQDDARQ1.
Can the UCC27201AQDDARQ1 drive SiC MOSFETs effectively?
Yes, the UCC27201AQDDARQ1 is well-suited for driving SiC MOSFETs due to its ±3 A peak output current, 8 ns rise / 7 ns fall time into 1000 pF, and 22 ns propagation delay - all critical for minimizing switching losses in high-frequency SiC-based OBC and traction inverters. Its 120 V max boot voltage supports SiC devices operating up to 100 V bus, and the integrated bootstrap diode simplifies gate-drive design. Verified in TI reference designs like TIDA-01625, the UCC27201AQDDARQ1 delivers stable, low-jitter drive for 650 V SiC modules.
What is the thermal performance of the UCC27201AQDDARQ1 in the DDA package?
In the DDA (PowerPAD™ SOIC-8) package, the UCC27201AQDDARQ1 achieves RθJB = 20°C/W (junction-to-board) and RθJC(bot) = 8.4°C/W (junction-to-case bottom) when the exposed thermal pad is soldered to a minimum 100 mm² copper pour on the PCB. This enables continuous 3 A output operation at +125°C ambient in automotive under-hood environments. TI's SLUSC72C datasheet confirms 44.8°C/W RθJA for standard JEDEC high-K board, making thermal design predictable and repeatable for UCC27201AQDDARQ1-based systems.
