Product details
Overview
UCC27200AD from Texas Instruments is a high-frequency, dual-channel N-channel MOSFET half-bridge driver with independent HI/LI inputs, 3A source/sink output current per channel, 22ns propagation delay, and integrated 0.65V/0.65Ω bootstrap diode. It operates across –40°C to 150°C and supports 120V maximum boot voltage for high-side switching in isolated DC–DC converters.
For engineers reviewing the UCC27200AD datasheet, UCC27200AD pinout, UCC27200AD application, or UCC27200AD equivalent, this page delivers verified electrical specs, thermal metrics, UVLO thresholds, timing matching data, and real-world implementation context for solar optimizers, telecom PSUs, and UPS systems.
Technical Context
The UCC27200AD uses a level-shift architecture to reference the high-side driver to the HS node, enabling robust operation with –18V negative voltage tolerance on HS and precise 1ns delay matching between HO and LO edges. Its CMOS-compatible input thresholds (6V rising / 5.6V falling) are supply-independent and support direct interfacing with microcontrollers or analog PWM controllers.
Undervoltage lockout acts independently on VDD (7.1V rising threshold, 0.5V hysteresis) and HB–HS differential (6.7V rising, 0.4V hysteresis), ensuring safe shutdown during brownout conditions. The on-chip bootstrap diode eliminates external discrete diodes while maintaining fast recovery (<20ns) and low forward drop (0.65V @ 100μA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 8–17 V: Enables compatibility with 12V control rails and wide-bandgap gate drive requirements. |
| HO/LO Output Current | ±3 A peak: Sufficient to drive high-Qg MOSFETs at >200 kHz without external buffers. |
| Propagation Delay | 22 ns typ: Supports high-frequency switching up to 1 MHz with tight timing control. |
| Rise/Fall Time | 8 ns / 7 ns @ 1000 pF: Minimizes transition losses in hard-switched topologies. |
| UVLO Thresholds | VDD: 7.1 V rise / 6.6 V fall; HB–HS: 6.7 V rise / 6.3 V fall - prevents erratic operation during startup or fault recovery. |
| Operating Temp | –40°C to 150°C: Qualified for under-hood automotive, industrial power, and energy storage environments. |
| Bootstrap Diode | 0.65 V VF @ 100 μA, 0.65 Ω RD: Reduces boot capacitor charging loss and improves efficiency in high-duty-cycle applications. |
Pinout & Package
UCC27200AD is packaged in an 8-pin SOIC (D package) with 4.9 mm × 3.9 mm body size and exposed thermal pad (PowerPAD™ variant not applicable to 'AD' suffix; AD denotes standard D package per TI orderable addendum).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Low-side supply input | Provides power to low-side driver and internal logic; decouple to VSS with 0.22–1.0 μF ceramic capacitor. |
| HB | High-side bootstrap supply | Connects to positive terminal of external bootstrap capacitor; internal diode charges capacitor when HS ≈ GND. |
| HO | High-side gate output | Drives high-side MOSFET gate referenced to HS node; capable of ±3 A into 1000 pF load. |
| HS | High-side source reference | Connects to source of high-side MOSFET; withstands –18 V transient and 120 V DC boot voltage. |
| HI | High-side input | CMOS-compatible control signal (6 V/5.6 V thresholds); enables independent high-side timing control. |
| LI | Low-side input | CMOS-compatible control signal; allows asynchronous or complementary PWM schemes. |
| VSS | Ground reference | Common return for low-side driver and logic; must be low-inductance connection to system ground plane. |
| LO | Low-side gate output | Drives low-side MOSFET gate referenced to VSS; matched timing with HO ensures <1 ns skew. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Diode | Eliminates external diode, reduces BOM count, and improves reliability by removing solder joint failure point. |
| Independent HI/LI Inputs | Enables flexible control modes including phase-shifted, asymmetrical, or dead-time-adjusted PWM without external logic. |
| –18 V HS Tolerance | Prevents latch-up or damage during fast dV/dt transients in high-noise power stages like LLC resonant converters. |
| 1 ns Delay Matching | Ensures precise synchronous switching of high- and low-side FETs, critical for minimizing shoot-through risk in half-bridge designs. |
| Enhanced ESD Protection | ±2000 V HBM rating protects against handling damage during PCB assembly and field service. |

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 |
|---|---|---|---|
| UCC27211D | Same pinout, but TTL-input thresholds (2.3 V/1.6 V) and no integrated bootstrap diode. | Requires external bootstrap diode; better suited for 3.3 V logic interfaces where CMOS thresholds cause marginal noise margin. | Select UCC27211D only if system uses 3.3 V controllers and external diode layout is acceptable. |
| IRS2004M | Higher 600 V floating voltage rating, but slower 60 ns propagation delay and no integrated bootstrap diode. | Targeted at motor drives and induction heating; lacks the 1 ns matching and thermal robustness for high-frequency PSU designs. | Choose IRS2004M only for non-isolated, lower-frequency (<100 kHz), higher-voltage (>200 V) applications where bootstrap diode can be added externally. |
Compared with UCC27200AD, UCC27211D requires external bootstrap components and offers different input logic, while IRS2004M trades speed and integration for higher voltage isolation-neither is pin-compatible nor functionally identical, making UCC27200AD optimal for compact, high-frequency, self-contained half-bridge designs.

FAQ
What is the maximum boot voltage supported by the UCC27200AD?
The UCC27200AD supports a maximum boot voltage of 120 V on the HB pin relative to HS. This rating enables reliable operation in high-bus-voltage applications such as 100 V secondary-side circuits in telecom PSUs and solar optimizers. Exceeding 120 V risks permanent damage to the internal bootstrap diode and level-shift circuitry. The device also tolerates –18 V on HS during fast transient events, enhancing noise immunity in noisy power stages.
Does the UCC27200AD require an external bootstrap diode?
No, the UCC27200AD integrates an on-chip bootstrap diode with 0.65 V forward voltage at 100 μA and 0.65 Ω dynamic resistance. This eliminates the need for an external diode, reducing component count, PCB area, and potential failure points. The internal diode is rated for full operational duty cycles and supports typical bootstrap capacitor values of 0.022–0.1 μF, depending on MOSFET gate charge and switching frequency.
What is the input threshold type of the UCC27200AD?
The UCC27200AD features CMOS-compatible input thresholds: 6.0 V (min) rising and 5.6 V (max) falling, with 0.4 V hysteresis. These thresholds are supply-independent and optimized for direct interface with 12 V PWM controllers or microcontrollers operating at 3.3 V or 5 V logic levels. This differs from the TTL-compatible UCC27201A, which uses 2.3 V/1.6 V thresholds.
How does the UCC27200AD handle undervoltage lockout?
The UCC27200AD implements independent UVLO circuits for both VDD and the HB–HS differential voltage. VDD UVLO triggers at 7.1 V (rising) with 0.5 V hysteresis, forcing both outputs low. HB–HS UVLO activates at 6.7 V (rising) with 0.4 V hysteresis and disables only the high-side driver. This dual UVLO prevents partial drive conditions that could cause shoot-through or MOSFET failure during brownout or startup.
What package options are available for the UCC27200AD?
The UCC27200AD is offered exclusively in the 8-pin SOIC (D package) with 4.9 mm × 3.9 mm body size and standard lead finish. Unlike other variants (e.g., UCC27200ADRMR in VSON-8), the 'AD' suffix denotes the SOIC-D package per TI's official orderable addendum. It does not include an exposed thermal pad; thermal performance relies on PCB copper area connected to VSS and adjacent traces.
