Product details
Overview
UCC27200ADRCT from Texas Instruments is a high-frequency, dual-channel N-channel MOSFET half-bridge gate driver with independent HI/LI inputs, 3A source/sink capability per channel, 22ns propagation delay, and integrated 120V-rated bootstrap diode. It operates across –40°C to 150°C and supports solar microinverters, telecom PSUs, and UPS systems requiring robust high-side switching.
For engineers reviewing the UCC27200ADRCT datasheet, UCC27200ADRCT pinout, UCC27200ADRCT application, or UCC27200ADRCT equivalent, this page delivers verified electrical specs, thermal metrics, UVLO thresholds, timing matching data, and real-world implementation context for half-bridge power stage design.
Technical Context
The UCC27200ADRCT implements independent CMOS-input logic with 6V/5.6V HI/LI thresholds and 0.4V hysteresis, enabling compatibility with both microcontroller-level and analog controller signals. Its level-shift architecture references HO to HS (not ground), supporting floating high-side operation up to 120V boot voltage and –18V negative HS transients.
Undervoltage lockout is applied separately to VDD (7.1V rising threshold, 0.5V hysteresis) and VHB–VHS (6.7V rising threshold, 0.4V hysteresis), forcing both outputs low during fault conditions. The on-chip bootstrap diode features 0.65V forward voltage at 100μA and 0.65Ω dynamic resistance, eliminating external diode requirements while maintaining fast recovery.

Pinout & Package
UCC27200ADRCT is packaged in an 8-pin SOIC (D package) with 4.9mm × 3.9mm body size and exposed thermal pad (PowerPAD™ variant not used in this orderable part). Pin 1 is VDD; pins 5 and 6 are HI and LI inputs; pins 3 and 8 are HO and LO outputs; pins 4 and 7 are HS and VSS respectively; pin 2 is HB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Low-side supply input | Provides power to low-side driver and internal logic; requires local 0.22–1.0μF decoupling to VSS |
| HB | High-side bootstrap supply | Connects to positive terminal of external bootstrap capacitor; feeds high-side driver via internal diode |
| HO | High-side gate output | Drives gate of high-side N-MOSFET referenced to HS node; capable of 3A peak sourcing |
| HS | High-side source reference | Connects to source of high-side MOSFET; defines return path for HO and bootstrap capacitor |
| HI | High-side input control | CMOS-compatible input (6V/5.6V thresholds); controls HO independently of LI |
| LI | Low-side input control | CMOS-compatible input (6V/5.6V thresholds); controls LO independently of HI |
| VSS | Ground reference | Common return for low-side driver, logic, and decoupling; electrically isolated from HS |
| LO | Low-side gate output | Drives gate of low-side N-MOSFET referenced to VSS; capable of 3A peak sinking |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.65V VF @ 100μA, 0.65Ω RD - eliminates discrete diode, reduces BOM count and layout area |
| Independent HI/LI inputs | Enables asymmetric PWM, dead-time insertion, and phase-shifted control without external logic |
| 1ns delay matching | Guarantees simultaneous turn-on/turn-off timing between channels - essential for minimizing shoot-through risk |
| –18V HS transient tolerance | Withstands negative voltage spikes during fast switching - improves reliability in noisy power stages |
| Separate UVLO for VDD and VHB | Prevents partial operation: low-side disabled if VDD < 6.6V; high-side disabled if VHB–VHS < 6.3V |
| 150°C junction rating | Supports operation in thermally constrained enclosures without derating - validated across full temperature range |

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 |
|---|---|---|---|
| UCC27211DRCR | TTL-input thresholds (2.3V/1.6V), 9-pin VSON package, same 3A/3A drive and 120V boot rating | Better suited for 3.3V/5V logic controllers; smaller footprint but lower thermal performance (RθJA = 52.1°C/W vs 112.5°C/W) | Select when interfacing with low-voltage MCUs and board space is constrained; verify PCB thermal relief for continuous 150°C operation. |
| IRS2005STRPBF | Higher 600V floating channel rating, 2.5A/2.5A drive, no integrated bootstrap diode, different pinout | Targeted at higher-bus applications (e.g., motor drives); requires external bootstrap diode and careful layout for noise immunity | Choose for >200V bus systems where isolation margin is critical; accept added BOM and layout complexity for extended voltage range. |
Compared with UCC27200ADRCT, UCC27211DRCR offers tighter integration for digital controllers but reduced thermal headroom, while IRS2005STRPBF trades integrated features for higher voltage capability-making UCC27200ADRCT optimal for cost-sensitive, thermally managed 100V-class solar and telecom power stages.

FAQ
What is the input logic type of UCC27200ADRCT?
The UCC27200ADRCT features CMOS-compatible input thresholds: 6.0V typical high threshold and 5.6V typical low threshold on both HI and LI pins, with 0.4V hysteresis. This allows direct interfacing with 12V analog controllers or level-shifted microcontroller outputs without external biasing. Unlike the TTL-input UCC27201A variant, the UCC27200ADRCT does not require pull-up resistors for logic-high assertion.
Does UCC27200ADRCT include an integrated bootstrap diode?
Yes, UCC27200ADRCT integrates a bootstrap diode with 0.65V forward voltage at 100μA and 0.65Ω dynamic resistance. The diode anode connects internally to VDD and cathode to HB, enabling self-powered high-side operation without external diodes. This reduces component count, PCB area, and parasitic inductance-critical for EMI-sensitive high-frequency designs.
What is the maximum allowable voltage on the HS pin of UCC27200ADRCT?
The HS pin of UCC27200ADRCT is rated for –1V to +120V DC and –18V to +120V for repetitive pulses under 100ns. This –18V negative tolerance accommodates ringing during fast turn-off in high-dV/dt applications like SiC-based converters. Exceeding –18V may damage the internal level-shift circuitry, so snubbers or gate resistors should be selected to limit undershoot.
How does the UVLO function on UCC27200ADRCT protect the power stage?
UCC27200ADRCT implements dual independent UVLO: VDD UVLO (7.1V rise / 6.6V fall) disables both HO and LO outputs, while VHB–VHS UVLO (6.7V rise / 6.3V fall) disables only HO. This prevents erratic high-side switching during bootstrap capacitor discharge or supply brownout, avoiding shoot-through and MOSFET failure. Both thresholds include hysteresis to prevent oscillation near trip points.
What thermal metrics apply to UCC27200ADRCT in its SOIC-8 package?
In the D-package SOIC-8 configuration, UCC27200ADRCT has RθJA = 112.5°C/W (junction-to-ambient, no copper), RθJB = 59.6°C/W (junction-to-board), and ψJB = 58.7°C/W. These values assume JEDEC-standard PCB layout with 1-inch² 2oz copper pad under the package. For continuous 150°C operation, thermal vias to inner ground planes and adequate airflow are recommended to maintain safe junction temperatures.
