Product details
Overview
UCC27201ADRMR from Texas Instruments is a 120V, 3A/3A high-side/low-side N-channel MOSFET gate driver IC with integrated bootstrap diode, independent TTL-compatible inputs, and dual undervoltage lockout (UVLO) for VDD and HB–HS. It delivers 22ns propagation delay, 8ns/7ns rise/fall times into 1000pF, and 1ns delay matching-enabling high-frequency half-bridge operation in solar microinverters and telecom power supplies.
For engineers reviewing the UCC27201ADRMR datasheet, UCC27201ADRMR pinout, UCC27201ADRMR application, or UCC27201ADRMR equivalent, this page provides verified specifications, thermal metrics for DRC package, real-world timing behavior across temperature, input threshold compatibility with 3.3V/5V controllers, and validated alternatives for half-bridge gate drive redesigns.
Technical Context
The UCC27201ADRMR implements independent CMOS-level-shifting logic for HI and LI inputs, enabling precise control of high-side (HO referenced to HS) and low-side (LO referenced to VSS) outputs. Its internal level-shift circuit ensures <1ns delay matching between HO and LO edges under all operating conditions.
It integrates a 0.65Ω dynamic-resistance bootstrap diode (VF = 0.65V @ 100μA) rated for 120V max HB–HS differential voltage and –18V negative HS transients. UVLO thresholds are 7.1V (VDD, 0.5V hysteresis) and 6.7V (HB–HS, 0.4V hysteresis), both specified over –40°C to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 3A source/sink per channel-supports fast switching of high-Qg MOSFETs up to 200kHz without external buffers. |
| Propagation delay | 22ns typical (HI→HO, LI→LO)-enables tight timing control in high-frequency resonant and hard-switched topologies. |
| Rise/fall time | 8ns/7ns into 1000pF load-minimizes transition losses during MOSFET turn-on/turn-off in 100V-class bridges. |
| Bootstrap diode VF | 0.65V @ 100μA-reduces boot capacitor recharge loss and improves efficiency vs discrete diode solutions. |
| UVLO thresholds | VDD rising: 7.1V; HB–HS rising: 6.7V-prevents shoot-through by disabling outputs during insufficient bias conditions. |
| Operating temperature | –40°C to 150°C TJ-qualified for under-hood automotive auxiliary power and industrial UPS environments. |
| HS pin rating | –18V transient tolerance-ensures robustness against negative ringing during high-dV/dt switching in LLC converters. |
Pinout & Package
The UCC27201ADRMR uses the DRC (9-pin VSON) package: 3.0mm × 3.0mm body with exposed thermal pad electrically connected to VSS. Thermal resistance is RθJB = 22.6°C/W, enabling high-power density layouts without external heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Low-side supply input | Provides power to low-side driver and internal logic; requires 0.22–1.0μF local decoupling to VSS. |
| HB (Pin 2) | High-side bootstrap supply | Connects to positive terminal of bootstrap capacitor; internal diode charges capacitor when HS ≈ GND. |
| HO (Pin 3) | High-side gate output | Drives high-side MOSFET gate referenced to HS; capable of 3A sink/source into capacitive loads. |
| HS (Pin 4) | High-side source reference | Connects to source of high-side MOSFET; supports –18V transients and 120V DC boot voltage swing. |
| HI (Pin 6) | High-side input | TTL-compatible (1.9–2.7V VIH); enables direct interface with 3.3V/5V PWM controllers without level shifters. |
| LI (Pin 7) | Low-side input | TTL-compatible (1.3–1.9V VIL); independent control allows asymmetric dead-time insertion and phase-shifted modulation. |
| VSS (Pin 8) | Ground reference | Common return for low-side driver and internal circuitry; thermally tied to exposed pad in DRC package. |
| LO (Pin 9) | Low-side gate output | Drives low-side MOSFET gate referenced to VSS; matched timing with HO prevents cross-conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.65Ω RD, 0.65V VF @ 100μA-eliminates external diode, reduces BOM count, and improves boot efficiency at light load. |
| Independent TTL inputs | VIH = 2.3V (typ), VIL = 1.6V (typ)-directly interfaces with MCU GPIOs, FPGA outputs, and digital PWM controllers. |
| Dual UVLO protection | Separate VDD and HB–HS monitoring-guarantees safe disable of both drivers during brownout or boot capacitor failure. |
| 1ns delay matching | Between HO and LO edges-enables precise dead-time control critical for ZVS/ZCS soft-switching topologies. |
| –18V HS transient tolerance | Withstands negative ringing on switch node-increases reliability in high-dV/dt GaN-based converters. |
Applications
| Solar Microinverter Half-Bridge | Telecom PSU LLC Resonant Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27211ADRMR | TTL inputs same; adds enable pin and higher 4A output drive; identical DRC package and pinout. | Required when system needs hardware enable/disable control or drives >3nC gate charge at >300kHz. | Select UCC27211ADRMR if enable functionality or extra current headroom is needed; otherwise UCC27201ADRMR suffices for standard half-bridge use. |
| IRS2005MTRPBF | CMOS inputs (VIH = 2.5V min); no integrated bootstrap diode; SOIC-8 package; 200V max HS rating. | Suitable where external bootstrap diode is acceptable and board space allows larger SOIC footprint. | Choose IRS2005MTRPBF only if legacy SOIC layout exists or higher 200V HS rating is mandatory; UCC27201ADRMR offers better integration and thermal performance. |
Compared with UCC27201ADRMR, UCC27211ADRMR adds enable control and 33% higher peak current but shares identical timing, UVLO, and thermal specs; IRS2005MTRPBF trades integration for higher voltage rating and requires external diode routing, increasing layout complexity and BOM cost.

FAQ
What is the input logic type of UCC27201ADRMR?
The UCC27201ADRMR features TTL-compatible inputs: VIH = 1.9–2.7V (typ 2.3V), VIL = 1.3–1.9V (typ 1.6V), with 0.7V hysteresis. This allows direct connection to 3.3V or 5V microcontrollers, FPGAs, and digital PWM controllers without level-shifting circuitry-unlike the CMOS-input UCC27200A variant. The input pulldown resistance is 68kΩ, ensuring clean low-state definition.
Does UCC27201ADRMR include an integrated bootstrap diode?
Yes, UCC27201ADRMR integrates a high-voltage bootstrap diode with VF = 0.65V @ 100μA and RD = 0.65Ω. The diode anode connects internally to VDD and cathode to HB, eliminating the need for an external discrete diode. This reduces PCB area, BOM count, and parasitic inductance-improving boot capacitor recharge efficiency and reliability in high-frequency half-bridge designs.
What is the maximum allowable voltage on the HS pin of UCC27201ADRMR?
The HS pin of UCC27201ADRMR supports –18V (repetitive pulse <100ns) to +120V DC. This –18V negative transient rating ensures robust operation against switch-node ringing in fast-switching GaN or SiC topologies. The absolute maximum HB–HS differential is 20V, and recommended operating HS voltage is –1V to +105V DC, making it suitable for 100V-class bridge applications.
How does the UVLO function on UCC27201ADRMR?
UCC27201ADRMR implements dual independent UVLO circuits: one monitors VDD (rising threshold 7.1V, 0.5V hysteresis) and disables both HO and LO; the other monitors HB–HS differential (rising threshold 6.7V, 0.4V hysteresis) and disables only HO. Both are active over –40°C to 150°C and prevent shoot-through during startup, brownout, or boot capacitor depletion-critical for system safety in mission-critical power supplies.
What package does UCC27201ADRMR use and what are its thermal characteristics?
UCC27201ADRMR uses the DRC package: 9-pin VSON, 3.0mm × 3.0mm body with exposed thermal pad connected to VSS. Its thermal metrics are RθJB = 22.6°C/W and RθJA = 52.1°C/W (JEDEC high-K board). This enables >2W continuous power dissipation with minimal board-level copper, supporting compact, fanless designs in solar and telecom applications where thermal headroom is constrained.
