Product details
Overview
UCC27212DPRT from Texas Instruments is a 120V-rated, dual-channel half-bridge gate driver IC with 3.7A source / 4.5A sink peak output current, 5V turn-off UVLO, and integrated 120V bootstrap diode - designed to drive N-channel MOSFETs in high-frequency bridge topologies including solar microinverters and telecom power supplies.
For engineers reviewing the UCC27212DPRT datasheet, UCC27212DPRT pinout, UCC27212DPRT application, or UCC27212DPRT equivalent, this page delivers verified technical context, real-world timing performance (7.2ns rise/5.5ns fall), thermal metrics (RθJA = 46.1°C/W), and precise pin-level design meaning for layout and reliability validation.
Technical Context
The UCC27212DPRT implements independent TTL-compatible HI/LI inputs with –10V to +20V input tolerance and 0.7V hysteresis, enabling direct interface to PWM controllers without external level-shifting or clamping. Its floating high-side driver references HO to HS and supports up to 100V DC switch-node voltage with –(24 – VDD)V negative transient tolerance.
Internal boot diode (VF = 0.65–0.85V @ 100μA) eliminates external diode need while maintaining fast recovery (20ns turnoff). Propagation delays are tightly matched (4ns typical tMON/tMOFF) across –40°C to +150°C, ensuring balanced dead-time control in synchronous-buck and full-bridge converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 7–17V operating; 20V absolute max - supports 12V bias rails with margin against transients. |
| Peak Output Current | 3.7A source / 4.5A sink - drives large Qg MOSFETs with minimal Miller plateau dwell time. |
| Rise/Fall Time | 7.2ns / 5.5ns @ 1000pF - enables >1MHz switching with low transition loss. |
| UVLO Threshold | 5.7V turn-on / 5.3V turn-off (0.4V hysteresis) - prevents erratic operation during brownout. |
| Propagation Delay | 10–30ns (tDLFF/tDHFF) - ensures predictable timing margins in high-speed control loops. |
| Delay Matching | 4–17ns (tMON/tMOFF) - minimizes transformer volt-second imbalance in bridge configurations. |
| Operating Temp | –40°C to +150°C junction - qualified for under-hood, industrial, and energy storage environments. |
Pinout & Package
UCC27212DPRT uses a 10-pin WSON package (DPR) with 4.00mm × 4.00mm body size and exposed thermal pad (PowerPAD™) electrically tied to VSS for enhanced thermal dissipation (RθJB = 22.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Low-side supply input | Decoupled to VSS via 0.22–4.7µF capacitor; powers LO stage and internal logic. |
| HB (Pin 2) | High-side bootstrap supply | Connects to positive terminal of bootstrap capacitor; internal diode charges HB from VDD. |
| HO (Pin 3) | High-side gate output | Drives high-side MOSFET gate referenced to HS; capable of 3.7A/4.5A peak current. |
| HS (Pin 4) | High-side source reference | Connects to MOSFET source; defines return for HO and enables floating operation up to 100V. |
| HI (Pin 7) | High-side input | TTL-compatible; accepts –10V to +20V; 68kΩ pulldown ensures defined state during float. |
| LI (Pin 8) | Low-side input | Independent TTL input; identical threshold/hysteresis as HI for symmetrical control. |
| LO (Pin 10) | Low-side gate output | Drives low-side MOSFET gate referenced to VSS; matches HO timing and drive strength. |
| VSS (Pin 9) | Ground reference | Common return for LO, logic, and thermal pad; must be low-impedance PCB plane. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 120V bootstrap diode | Eliminates external diode BOM cost and layout area; VF = 0.65–0.85V at 100μA. |
| –10V to +20V input tolerance | Withstands gate-drive transformer undershoot/overshoot without clamping diodes. |
| Symmetrical 5V UVLO on VDD & VHB | Ensures coordinated shutdown of both drivers during undervoltage, preventing shoot-through. |
| 4ns typical delay matching (tMON/tMOFF) | Reduces duty-cycle error and transformer saturation risk in phase-shifted full-bridge designs. |
| Exposed PowerPAD™ thermal pad | Enables RθJB = 22.1°C/W - critical for sustained 500kHz+ operation in compact enclosures. |
Applications
| Solar Microinverters | Telecom Power Supplies |

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 |
|---|---|---|---|
| UCC27201DPRT | No integrated bootstrap diode; requires external diode; same 3.7A/4.5A drive and 5V UVLO. | Lacks 120V diode rating - unsuitable for telecom surge-critical designs. | Select when board space allows external diode and cost sensitivity outweighs integration benefit. |
| LM5113SDX/NOPB | Higher 5A/5A drive; 105V max HB; no HS negative voltage tolerance; different pinout (SOIC-8). | Not rated for –(24–VDD)V HS transients - limits use in high-dV/dt motor drives or flyback snubbers. | Choose for higher-current GaN FETs where thermal headroom exists and layout permits SOIC-8 footprint. |
Compared with UCC27212DPRT, UCC27201DPRT trades integration for flexibility and lower cost, while LM5113SDX/NOPB offers higher drive strength but sacrifices robustness in high-noise, high-transient environments - making UCC27212DPRT optimal for mission-critical 100V-class power stages.

FAQ
What is the maximum allowable voltage on the HS pin of the UCC27212DPRT?
The UCC27212DPRT HS pin supports up to 100V DC under steady-state conditions and tolerates –(24 – VDD)V (e.g., –12V at VDD = 12V) for repetitive pulses <100ns. This specification protects the high-side channel from negative transients caused by parasitic inductance in high-dV/dT switching nodes - a key requirement in hard-switched bridge topologies using the UCC27212DPRT.
Does the UCC27212DPRT require an external bootstrap diode?
No, the UCC27212DPRT integrates a 120V-rated bootstrap diode between VDD and HB pins. This eliminates the need for an external diode, reduces BOM count, and improves reliability in high-reliability applications such as solar microinverters and telecom power supplies where the UCC27212DPRT is commonly deployed.
What is the purpose of the 5V UVLO in the UCC27212DPRT?
The UCC27212DPRT features a 5V turn-off UVLO on both VDD and VHB supplies to prevent erratic gate drive during brownout conditions. With 0.4V hysteresis, it ensures coordinated shutdown of high-side and low-side outputs - avoiding shoot-through and protecting downstream MOSFETs. This behavior is explicitly specified in the UCC27212DPRT electrical characteristics table and validated across –40°C to +150°C.
Can the UCC27212DPRT drive GaN FETs?
Yes, the UCC27212DPRT can drive enhancement-mode GaN FETs requiring ≤12V gate drive, thanks to its 3.7A/4.5A peak current, 7.2ns rise time, and tight 4ns delay matching - all critical for minimizing switching loss in >500kHz GaN-based converters. However, its 12V minimum VDD limit means it is not suitable for 5V-only GaN drivers; the UCC27212DPRT operates optimally at 12V bias in GaN half-bridge applications.
How does the UCC27212DPRT handle input noise on HI and LI pins?
The UCC27212DPRT incorporates 0.7V input hysteresis and 68kΩ internal pulldown resistors on HI and LI pins, providing robust noise immunity against EMI and ground bounce. Input thresholds are specified at 1.7–2.55V (high) and 1.2–1.9V (low), with hysteresis confirmed across temperature - enabling reliable operation in noisy industrial environments where the UCC27212DPRT is frequently used.
