Product details
Overview
UCC27201DDA from Texas Instruments is a high-frequency, dual-channel N-channel MOSFET gate driver for half-bridge topologies, featuring independent HI/LI inputs, 3A source/sink output current per channel, 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 requiring robust high-side switching at up to 105V HS voltage.
For engineers reviewing the UCC27201DDA datasheet, UCC27201DDA pinout, UCC27201DDA application, or UCC27201DDA equivalent, this page delivers verified technical context on TTL-compatible input thresholds (1.9–2.7V VIH), 8V UVLO for both drivers, 1ns delay matching, and SOIC-8 PowerPAD™ thermal performance-critical for high-reliability power conversion designs.
Technical Context
The UCC27201DDA implements independent high-side and low-side drivers referenced to HS and VSS respectively, with an internal level-shift circuit enabling precise timing control of the HO output relative to the switch node. Its integrated bootstrap diode eliminates external discrete diodes while supporting up to 120V HB voltage and –5V negative HS transients.
It features dual undervoltage lockout (UVLO) circuits: VDD UVLO triggers at 7.1V (0.5V hysteresis) disabling both outputs, and VHB UVLO activates at 6.7V (0.4V hysteresis) disabling only HO. Input logic uses TTL-compatible thresholds (VIH = 2.3V typ, VIL = 1.6V typ) with 68kΩ pulldown resistance and 4pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 3A source and 3A sink per channel-enables fast switching of high-Qg MOSFETs without external buffers |
| Propagation delay | 22ns typical-minimizes timing skew in high-frequency (>200kHz) half-bridge operation |
| Rise/fall time | 8ns/7ns with 1000pF load-supports clean edge integrity in noise-sensitive power stages |
| Delay matching | 1ns typical between HI→HO and LI→LO-ensures synchronous turn-on/turn-off critical for shoot-through prevention |
| Bootstrap diode VF/RD | 0.65V forward voltage / 0.65Ω dynamic resistance-reduces conduction loss and improves boot capacitor recharge efficiency |
| UVLO thresholds | VDD rising: 7.1V (0.5V hysteresis); VHB rising: 6.7V (0.4V hysteresis)-prevents erratic operation during brownout or startup |
| Operating temperature | –40°C to 150°C junction-validated for under-hood automotive, industrial UPS, and solar optimizer environments |
Pinout & Package
The UCC27201DDA uses an 8-pin SOIC package with exposed PowerPAD™ thermal pad (DDA variant), measuring 3.9mm × 4.9mm. The PowerPAD™ is electrically tied to VSS and must be soldered to a large PCB ground plane for optimal thermal performance (RθJB = 20°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Low-side supply input | Provides power to low-side driver and bootstrap diode anode; requires 0.22–1μF local decoupling to VSS |
| HB | High-side bootstrap supply | Connects to positive terminal of external bootstrap capacitor; internal diode charges capacitor during LO conduction |
| HO | High-side gate drive output | Drives high-side MOSFET gate referenced to HS; capable of 3A peak current into capacitive load |
| HS | High-side source reference | Connects to source of high-side MOSFET; serves as return path for HB capacitor and reference for HO output |
| HI | High-side input signal | TTL-compatible logic input (VIH = 2.3V typ); controls HO independently of LI for flexible PWM or complementary drive |
| LI | Low-side input signal | TTL-compatible logic input (VIL = 1.6V typ); controls LO independently-enables dead-time insertion or phase-shift control |
| LO | Low-side gate drive output | Drives low-side MOSFET gate referenced to VSS; matched timing with HO prevents shoot-through |
| VSS | Ground reference | Common return for low-side driver, input logic, and PowerPAD™; must be low-impedance connection to system ground |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 120V-rated, 0.65Ω RD, 0.65V VF-eliminates external diode, reduces BOM count, and improves boot reliability in high-dV/dt environments |
| TTL-compatible inputs | VIH = 2.3V, VIL = 1.6V, 68kΩ pulldown-directly interfaces with 3.3V/5V microcontrollers and digital PWM controllers without level shifters |
| Negative HS transient tolerance | –5V capability on HS pin-survives ringing and cross-conduction-induced negative excursions in hard-switching converters |
| Dual independent UVLO | Separate VDD and VHB monitoring-ensures safe shutdown of low-side driver during main supply fault and high-side driver during bootstrap failure |
| PowerPAD™ thermal enhancement | RθJB = 20°C/W-enables >2W continuous power dissipation in compact SOIC footprint without heatsink |

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 |
|---|---|---|---|
| UCC27200DDA | CMOS-compatible inputs (VIH = 6V, VIL = 5.6V); identical pinout, thermal, and drive specs | Requires ≥5V logic interface; unsuitable for 3.3V microcontrollers without level shifting | Select UCC27200DDA when interfacing with analog PWM controllers or 5V FPGA outputs where higher noise immunity is prioritized |
| IRS2004PBF | Higher VBS rating (600V), no integrated bootstrap diode, 2.5A peak current, SOIC-8 package | Needs external bootstrap diode; better suited for high-voltage PFC stages but adds BOM complexity | Choose IRS2004PBF only when operating above 120V HS or requiring industry-standard 600V bootstrap margin in industrial motor drives |
Compared with UCC27201DDA, UCC27200DDA offers superior noise immunity at the cost of 3.3V incompatibility, while IRS2004PBF trades integration for higher voltage headroom-making UCC27201DDA optimal for cost-sensitive, space-constrained 100V-class solar and telecom converters requiring TTL-level simplicity.

FAQ
What is the input logic compatibility of the UCC27201DDA?
The UCC27201DDA features TTL-compatible inputs with a typical high-level input threshold (VIH) of 2.3V and low-level threshold (VIL) of 1.6V, enabling direct interface with 3.3V and 5V microcontrollers, FPGAs, and digital PWM controllers without external level shifters. This differs from the UCC27200DDA, which uses CMOS thresholds (VIH = 6V). The UCC27201DDA's 68kΩ internal pulldown resistor ensures reliable low-state termination.
Does the UCC27201DDA include an integrated bootstrap diode?
Yes, the UCC27201DDA integrates a 120V-rated bootstrap diode with 0.65V forward voltage and 0.65Ω dynamic resistance, connecting internally between VDD and HB pins. This eliminates the need for an external discrete diode, reduces PCB area, and improves reliability in high-dV/dt half-bridge applications such as solar microinverters. External bootstrap capacitance remains required (0.022–0.1μF).
What thermal advantages does the DDA package offer over standard SOIC?
The UCC27201DDA's DDA package incorporates an exposed PowerPAD™ thermal pad electrically connected to VSS, achieving a junction-to-board thermal resistance (RθJB) of 20°C/W-more than 5× better than the standard D package (59.6°C/W). When soldered to a 1-in² copper pour, it enables >2W continuous power dissipation without a heatsink, making it ideal for compact, high-power-density designs like telecom PSUs.
How does the UCC27201DDA prevent shoot-through in half-bridge configurations?
The UCC27201DDA prevents shoot-through through 1ns typical delay matching between HI→HO and LI→LO propagation paths, ensuring tightly synchronized turn-on and turn-off edges. Combined with independent HI and LI inputs, it allows precise dead-time insertion in the controller-critical for avoiding simultaneous conduction in high-side and low-side MOSFETs. Its dual UVLO also forces both outputs low during supply faults.
What is the maximum allowable voltage on the HS pin of the UCC27201DDA?
The UCC27201DDA supports a maximum DC voltage of 105V on the HS pin under recommended operating conditions, with absolute maximum rating of 120V. It also tolerates –5V negative transients (repetitive pulses <100ns), making it suitable for hard-switching topologies where ringing may pull HS below ground. Exceeding 105V DC risks violating UVLO hysteresis margins and degrading bootstrap capacitor charging efficiency.
