Product details
Overview
UCC27201ADRMT from Texas Instruments is a 120V, 3A/3A high-side/low-side N-channel MOSFET driver with independent TTL-compatible inputs, integrated 0.65V/0.65Ω bootstrap diode, 8V UVLO on both sides, and 1ns delay matching - used in half-bridge power stages of solar microinverters and telecom PSUs.
For engineers reviewing the UCC27201ADRMT datasheet, UCC27201ADRMT pinout, UCC27201ADRMT application, or UCC27201ADRMT equivalent, this page delivers verified electrical specs, thermal metrics, SOIC-8 package mapping, real-world timing behavior (22ns propagation, 8ns/7ns rise/fall), and validated alternatives for high-reliability isolated DC-DC and energy storage designs.
Technical Context
The UCC27201ADRMT implements dual independent input control with TTL thresholds (VIH = 2.3V, VIL = 1.6V) and level-shifted high-side drive referenced to HS pin, enabling robust operation under –18V negative HS transients and up to 120V boot voltage. Its internal bootstrap diode eliminates external discrete diodes while maintaining fast recovery (20ns turnoff).
UVLO is independently applied to VDD (7.1V rising threshold, 0.5V hysteresis) and VHB–VHS differential (6.7V rising, 0.4V hysteresis), forcing both outputs low during undervoltage conditions. Propagation delays are matched within 1ns across temperature (–40°C to 150°C) and supply (8–17V), supporting >1MHz switching in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 8–17 V - supports 12V nominal bias while tolerating transient overvoltage in industrial power rails |
| Max Boot Voltage | 120 V - enables direct use in 100V-class half-bridges without external voltage clamping |
| Output Current | ±3 A peak - drives gate charge of >10nC MOSFETs at <20ns dV/dt in CCM PFC and LLC converters |
| Propagation Delay | 22 ns typical - ensures tight timing control in high-frequency resonant and synchronous rectifier designs |
| Rise/Fall Time | 8 ns / 7 ns @ 1000 pF - minimizes switching losses in SiC and GaN-based power stages |
| Delay Matching | 1 ns max - prevents shoot-through in phase-shifted full-bridge and active-clamp forward converters |
| UVLO Thresholds | VDD: 7.1 V (0.5 V hysteresis); VHB–VHS: 6.7 V (0.4 V hysteresis) - provides independent fault detection for bootstrap integrity |
| Operating Temp | –40°C to +150°C - qualified for under-hood automotive auxiliary supplies and outdoor solar inverters |
Pinout & Package
UCC27201ADRMT 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 used in this orderable part). Pin 1 is VDD; pins 5 and 6 are HI and LI inputs; HO and LO outputs are on pins 3 and 8; HS and HB are pins 4 and 2; VSS is pin 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Low-side supply input | Provides power to low-side driver and internal logic; requires 0.22–1.0 μF local decoupling to VSS |
| HB (Pin 2) | High-side bootstrap supply node | Connects to positive terminal of bootstrap capacitor; internal diode charges capacitor when HS ≈ GND |
| HO (Pin 3) | High-side gate output | Sinks/sources ±3 A to drive high-side MOSFET gate; referenced to HS pin, not ground |
| HS (Pin 4) | High-side source reference | Connects to source of high-side MOSFET; withstands –18 V transient and 120 V DC common-mode |
| HI (Pin 5) | High-side input signal | TTL-compatible (1.6–2.3 V thresholds); independent of LI for asymmetric PWM or dead-time control |
| LI (Pin 6) | Low-side input signal | TTL-compatible (1.6–2.3 V thresholds); allows separate enable/disable of low-side switch |
| VSS (Pin 7) | Ground reference | Common return for low-side driver and logic; electrically isolated from HS but thermally coupled via die |
| LO (Pin 8) | Low-side gate output | Sinks/sources ±3 A to drive low-side MOSFET gate; referenced to VSS (GND) |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.65 V forward drop, 0.65 Ω dynamic resistance - eliminates external diode, reduces BOM count and layout area |
| Independent HI/LI inputs | Full control flexibility for non-complementary PWM, burst mode, or adaptive dead-time insertion |
| –18 V HS pin tolerance | Withstands negative transients during hard commutation or shoot-through events without latch-up |
| 1 ns delay matching | Guarantees precise edge alignment between HO and LO, critical for zero-voltage switching (ZVS) timing |
| ESD robustness | ±2000 V HBM, ±1000 V CDM - meets IPC/JEDEC standards for automated assembly and field reliability |
| Thermal performance | RθJA = 112.5°C/W (SOIC-8) - supports >1W dissipation with standard 2-layer PCB and 1-in² copper pour |

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 |
|---|---|---|---|
| UCC27200ADRMT | CMOS input thresholds (6 V/5.6 V), higher input impedance (200 kΩ), no open-drain structure | Better suited for analog controller interfaces or 12 V logic systems; less compatible with 3.3 V MCU outputs | Select UCC27200ADRMT when driving from 12 V PWM sources or where noise immunity outweighs logic-level compatibility |
| IRS2004PBF | Higher VBS rating (600 V), no integrated bootstrap diode, 1.4 A output, SOIC-8 package | Requires external bootstrap diode and larger gate resistors; rated for 600 V bridge applications (e.g., motor drives) | Choose IRS2004PBF only for >400 V DC link designs where UCC27201ADRMT's 120 V limit is insufficient |
Compared with UCC27200ADRMT, the UCC27201ADRMT offers lower input thresholds for direct 3.3 V/5 V MCU interfacing, while IRS2004PBF trades integrated diode convenience for higher voltage capability - making UCC27201ADRMT optimal for cost-sensitive, space-constrained 100 V-class isolated DC-DC and renewable energy converters.

FAQ
What is the input voltage threshold type for UCC27201ADRMT?
The UCC27201ADRMT features TTL-compatible input thresholds: VIH = 2.3 V (typical), VIL = 1.6 V (typical), with 0.7 V hysteresis. This allows direct interfacing with 3.3 V or 5 V microcontrollers and FPGAs without level-shifting circuitry. Unlike the CMOS-input UCC27200A, the UCC27201ADRMT uses an internal pulldown resistor (68 kΩ) and open-drain-like input structure to achieve these logic-level thresholds.
Does UCC27201ADRMT include an integrated bootstrap diode?
Yes, the UCC27201ADRMT integrates a bootstrap diode with 0.65 V forward voltage at 100 µA and 0.65 Ω dynamic resistance. The diode anode connects internally to VDD and cathode to HB, eliminating the need for an external discrete diode in most half-bridge designs. This reduces bill-of-materials count, PCB area, and potential failure points associated with external diode selection and placement.
What is the maximum allowable voltage on the HS pin of UCC27201ADRMT?
The UCC27201ADRMT supports a maximum DC voltage of 120 V on the HS pin, with transient capability up to –18 V (repetitive pulses <100 ns). This rating enables reliable operation in 100 V-class half-bridge circuits where the HS node swings between near-ground and high bus voltage. The –18 V tolerance prevents false triggering or damage during negative ringing caused by parasitic inductance in high-dI/dt switching events.
How does the UVLO function on UCC27201ADRMT?
The UCC27201ADRMT implements independent undervoltage lockout for both VDD and VHB–VHS: VDD UVLO triggers at 7.1 V (rising) with 0.5 V hysteresis, disabling both drivers; VHB UVLO triggers at 6.7 V (rising) with 0.4 V hysteresis, disabling only the high-side driver. This dual UVLO ensures safe operation during bootstrap capacitor discharge or main supply sag, preventing partial drive that could cause shoot-through or MOSFET overstress.
What package type is used for UCC27201ADRMT?
The UCC27201ADRMT is supplied in an 8-pin SOIC (D package) with 4.9 mm × 3.9 mm body dimensions and standard gull-wing leads. It does not include an exposed thermal pad (unlike the DDA variant), so thermal performance relies on PCB copper area and solder joint quality. The RθJA is specified at 112.5°C/W, requiring adequate board-level heatsinking for continuous >0.5 W dissipation.
