Product details
Overview
UCC27200DRMT from Texas Instruments is a high-frequency, dual-channel N-channel MOSFET gate driver for half-bridge topologies, featuring independent high-side and low-side inputs, 3A source/sink output current, 22ns propagation delay, and integrated 120V-rated bootstrap diode with 0.65Ω dynamic resistance. It operates across –40°C to 150°C and supports solar microinverters and telecom power supplies.
For engineers reviewing the UCC27200DRMT datasheet, UCC27200DRMT pinout, UCC27200DRMT application, or UCC27200DRMT equivalent, this page delivers verified technical context, package-specific pin functions, real-world switching performance metrics, thermal behavior under load, and validated alternative options for high-voltage half-bridge gate drive designs.
Technical Context
The UCC27200DRMT implements independent CMOS-input logic with 6V/5.6V thresholds and 0.4V hysteresis, enabling compatibility with both microcontroller-level and analog controller signals. Its level-shift architecture ensures 1ns delay matching between HO and LO outputs while referencing HO to the HS node (–5V to 105V) and LO to VSS.
Undervoltage lockout acts separately on VDD (7.1V rising threshold, 0.5V hysteresis) and HB–HS differential (6.7V rising threshold, 0.4V hysteresis), forcing both outputs low during fault conditions. The on-chip bootstrap diode eliminates external discrete diodes and supports up to 120V boot voltage with fast 20ns turnoff time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD operating range | 8–17 V - powers low-side driver and internal logic; decoupling capacitor 0.22–1 μF required at VDD-to-VSS. |
| HS voltage range | –5 V to 105 V DC - enables high-side operation in 100 V-class half-bridges with negative transient tolerance. |
| Output current | ±3 A peak - drives large gate capacitances (e.g., >2 nF) with sub-10 ns rise/fall times into 1000 pF loads. |
| Propagation delay | 22 ns typical - ensures tight timing control in high-frequency converters (>200 kHz) without added latency. |
| Delay matching | ≤1 ns typical - maintains precise dead-time integrity between high-side and low-side switching edges. |
| UVLO thresholds | VDD: 7.1 V ±0.5 V; HB–HS: 6.7 V ±0.4 V - prevents erratic switching during brownout or bootstrap capacitor discharge. |
| Operating temperature | –40°C to +150°C - qualified for under-hood automotive, industrial UPS, and energy storage system environments. |
Pinout & Package
UCC27200DRMT uses the DRM (VSON-8) package: 4.0 mm × 4.0 mm body, exposed thermal pad electrically tied to VSS, rated RθJB = 21.3°C/W. Thermal pad must connect to PCB ground plane for reliable 150°C junction operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Low-side supply input | Provides power to low-side driver and logic; requires local 0.22–1 μF ceramic decoupling to VSS. |
| HB (Pin 2) | High-side bootstrap supply | Connects to positive terminal of bootstrap capacitor; internal diode anode ties to VDD, cathode to HB. |
| HO (Pin 3) | High-side gate output | Drives high-side MOSFET gate referenced to HS; capable of ±3 A into capacitive loads. |
| HS (Pin 4) | High-side source reference | Connects to source of high-side MOSFET; defines return path for HO and bootstrap capacitor negative terminal. |
| HI (Pin 5) | High-side input | CMOS-compatible input (6 V/5.6 V thresholds); controls HO independently of LI for flexible PWM or complementary drive. |
| LI (Pin 6) | Low-side input | CMOS-compatible input (6 V/5.6 V thresholds); controls LO independently of HI; pulldown resistance 100–350 kΩ. |
| VSS (Pin 7) | Ground reference | Common return for low-side driver, logic, and thermal pad; must be low-inductance connection to PCB ground plane. |
| LO (Pin 8) | Low-side gate output | Drives low-side MOSFET gate referenced to VSS; matched to HO within 1 ns for precise timing control. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.65 V forward drop at 100 µA, 0.65 Ω dynamic resistance - eliminates external diode, reduces BOM count and layout area. |
| Independent input control | Separate HI and LI pins with CMOS thresholds - enables non-overlapping, phase-shifted, or synchronous rectification drive schemes. |
| Negative HS voltage tolerance | –5 V on HS pin - accommodates shoot-through transients and improves robustness in hard-switching converters. |
| Matched propagation delays | ≤1 ns HO/LO delay mismatch - preserves dead-time accuracy critical for preventing cross-conduction in half-bridge stages. |
| High-temperature operation | Specified from –40°C to +150°C - supports placement near power switches in compact, thermally constrained designs. |

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 |
|---|---|---|---|
| UCC27211DRMT | Same DRM package and pinout; TTL-compatible inputs (2.3 V/1.6 V thresholds) instead of CMOS. | Requires 3.3 V logic-level PWM sources; less suitable for 5 V or analog controller interfaces. | Select when driving from microcontrollers with 3.3 V GPIO; verify input hysteresis margin against noise in noisy power environments. |
| LM5109BSDX/NOPB | SOIC-8 package; 1 A source/1 A sink; no integrated bootstrap diode; 60 V max HS rating. | Limited to ≤60 V half-bridges; requires external bootstrap diode and larger layout area. | Choose for cost-sensitive, lower-voltage (<60 V) applications where thermal performance and integration are secondary. |
Compared with UCC27200DRMT, UCC27211DRMT offers identical packaging and performance but targets 3.3 V logic systems, whereas LM5109BSDX/NOPB trades integration and voltage rating for lower cost and wider distributor availability in legacy SOIC footprints.

FAQ
What is the maximum allowable voltage on the HS pin of the UCC27200DRMT?
The UCC27200DRMT supports a maximum DC voltage of 105 V on the HS pin, with transient tolerance up to –5 V for <100 ns pulses. This rating enables use in 100 V nominal bus applications such as solar microinverters and telecom rectifiers. Exceeding 105 V DC risks permanent damage per Absolute Maximum Ratings. Always verify HS voltage swing-including ringing-against this limit in final layout.
Does the UCC27200DRMT require an external bootstrap diode?
No, the UCC27200DRMT integrates a 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 and PCB area. However, an external bootstrap capacitor (0.022–0.1 µF) remains mandatory between HB and HS pins to sustain high-side bias during continuous conduction.
How does the UCC27200DRMT handle undervoltage conditions on the high-side supply?
The UCC27200DRMT monitors the VHB–HS differential voltage and triggers high-side UVLO if it falls below 6.7 V (rising threshold) with 0.4 V hysteresis. When activated, the HO output is forced low to prevent partial turn-on of the high-side MOSFET. This protects against shoot-through during bootstrap capacitor discharge or startup undershoot, ensuring safe operation in hard-switching topologies.
What is the thermal pad connection requirement for the UCC27200DRMT in the DRM package?
The exposed thermal pad of the UCC27200DRMT (DRM package) is electrically connected to VSS and must be soldered to a large copper pour or internal ground plane. TI specifies RθJB = 21.3°C/W only when the pad is properly connected; omitting this connection degrades thermal performance by >100°C/W and risks thermal shutdown above 100°C ambient. Use ≥4 thermal vias under the pad.
Can the UCC27200DRMT drive SiC or GaN MOSFETs?
Yes, the UCC27200DRMT is suitable for driving SiC and GaN MOSFETs due to its 3 A peak source/sink capability, 8 ns/7 ns rise/fall times into 1000 pF, and –5 V to 105 V HS rating. Its fast propagation delay (22 ns) and 1 ns delay matching help minimize switching losses in wide-bandgap devices. Ensure gate resistor selection balances EMI and dV/dt stress per device datasheet recommendations.
