Product details
Overview
UCC27536DBVT from Texas Instruments is a single-channel, high-speed MOSFET/IGBT gate driver in SOT-23-5 package with 2.5-A source / 2.5-A sink peak drive current, 17-ns typical propagation delay, and 10–35-V VDD operating range. It features inverting input logic, enable pin with TTL-compatible threshold, and rail-to-rail output swing - deployed in DC-DC converters and SiC FET gate-drive stages where asymmetric turn-on/turn-off control is not required.
For engineers reviewing the UCC27536DBVT datasheet, UCC27536DBVT pinout, UCC27536DBVT application, or UCC27536DBVT equivalent, this page delivers verified technical context, exact pin functions, real-world application mappings, and two validated alternative parts for gate-driver selection in power-conversion designs requiring robust 140°C operation and ±5-V input tolerance.
Technical Context
The UCC27536DBVT implements an inverting-input gate driver architecture with dedicated EN pin, enabling precise control of power-switch conduction timing. Its asymmetrical internal drive stage is configured for matched 2.5-A source/sink capability - distinct from UCC27537's 5-A sink - and supports negative input voltage tolerance down to –5 V DC relative to GND.
Unlike split-output variants (e.g., UCC27531), UCC27536DBVT uses a single-output configuration (OUT pin) with integrated pull-up/pull-down paths, eliminating external resistor tuning for slew rate while maintaining immunity to ground bounce via fast 15-ns rise / 10-ns fall times (1.8-nF load).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 10 V to 35 V - supports wide-input industrial and automotive DC-DC supplies without external regulation |
| Peak Output Current | 2.5 A source / 2.5 A sink - sufficient for driving 10-nF gate capacitance at >1-MHz switching in SiC half-bridges |
| Propagation Delay | 17 ns typical - enables precise timing alignment in synchronous rectification and phase-shifted topologies |
| Rise/Fall Time | 15 ns / 10 ns (1.8-nF load) - minimizes switching losses in high-frequency GaN/SiC applications |
| Input Threshold | TTL/CMOS compatible (0.8–1.2 V low, 1.8–2.2 V high) - ensures reliable interfacing with microcontrollers and PWM controllers |
| UVLO Threshold | 8.9 V turn-on / 8.2 V turn-off (0.7 V hysteresis) - prevents erratic switching during brown-out conditions |
| Operating Temp | –40°C to +140°C - qualified for under-hood automotive and industrial motor-control environments |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads; thermally optimized for PCB copper pour on GND pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Pull low to disable output; open or high enables driver - provides system-level fault shutdown without controller reconfiguration |
| 2 - GND | Power and signal reference | Primary return path for all currents; must be low-inductance connection to minimize ground bounce during 2.5-A transients |
| 3 - IN− | Inverting logic input | Active-low input: high → output low, low → output high - simplifies direct interface with comparator outputs or inverted PWM signals |
| 4 - OUT | Gate-drive output | Single-pin push-pull output delivering 2.5-A source/sink - eliminates need for external bootstrap diode or level shifter in low-side configurations |
| 5 - VDD | Bias supply input | Accepts 10–35 V; internal UVLO ensures output remains low until stable supply is established |
Key Features
| Feature | Design Value |
|---|---|
| Inverting input logic | Eliminates external inverter IC when interfacing with error-amplifier or comparator outputs in current-mode controllers |
| TTL/CMOS input thresholds | Ensures compatibility with 3.3-V and 5-V logic families without level-shifting circuitry |
| –5-V input tolerance | Withstands negative transients during layout parasitics or ESD events, reducing need for clamping diodes |
| Output held low on floating inputs | Prevents unintended power-switch turn-on during startup or controller reset - critical for safety-critical inverters |
| 140°C max junction temperature | Enables placement near hot power stages in compact SMPS and onboard chargers without derating |
Applications
| Motor Drive Half-Bridge | Solar Microinverter Gate Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gate-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27537DBVT | 2.5-A source / 5-A sink; same pinout, non-inverting input | Better suited for Miller-effect-prone IGBTs requiring stronger turn-off current | Select UCC27537DBVT when driving high-Ciss devices or needing faster turn-off in hard-switched topologies |
| TPS2828DBVR | Pin-to-pin compatible; 2-A source / 3-A sink; 12-V max VDD | Limited to lower-voltage DC-DC applications due to 12-V VDD ceiling | Choose TPS2828DBVR only for cost-sensitive 5–12-V systems where 35-V headroom is unnecessary |
Compared with UCC27536DBVT, UCC27537DBVT offers higher sink current for improved Miller immunity but requires non-inverting logic design, while TPS2828DBVR trades voltage range and drive strength for legacy compatibility in low-voltage rails.

FAQ
What is the input logic polarity of the UCC27536DBVT?
The UCC27536DBVT features inverting input logic on its IN− pin: a logic-high input forces the OUT pin low, and a logic-low input drives OUT high. This eliminates external inverters when interfacing with comparators or error amplifiers whose outputs are active-high during fault conditions. The UCC27536DBVT does not support non-inverting operation - use UCC27537DBVT for that functionality.
Does the UCC27536DBVT support negative voltage on its input pins?
Yes, the UCC27536DBVT input pins (IN− and EN) tolerate –5 V DC relative to GND under continuous conditions, and –6.5 V for 1.5-µs pulses. This specification allows the UCC27536DBVT to withstand ground bounce, transformer ringing, or ESD transients without external clamping diodes - a key reliability feature in noisy power-conversion environments.
What is the maximum recommended VDD voltage for continuous operation of the UCC27536DBVT?
The UCC27536DBVT supports continuous VDD operation from 10 V to 35 V, with absolute maximum rating at 35 V. For long-term reliability, TI recommends limiting VDD to ≤32 V under normal operating conditions per the Recommended Operating Conditions table. Exceeding 32 V may accelerate parametric drift or reduce lifetime in high-temperature applications.
Can the UCC27536DBVT drive both MOSFETs and IGBTs effectively?
Yes, the UCC27536DBVT is explicitly characterized and qualified for driving both N-channel MOSFETs and NPT IGBTs. Its 2.5-A source/sink capability, 17-ns propagation delay, and rail-to-rail output swing meet the dynamic gate-drive requirements of modern 650-V and 1200-V IGBT modules and 100-V to 900-V Si/SiC MOSFETs in hard-switched and resonant topologies.
Is the UCC27536DBVT pin-to-pin compatible with other members of the UCC2753x family?
No - the UCC27536DBVT (SOT-23-5, inverting input, EN pin) is not pin-to-pin compatible with UCC27531 (SOT-23-6, split output) or UCC27533 (SOT-23-5, dual differential input). However, it is pin-to-pin compatible with UCC27537DBVT (same pinout, non-inverting input) and TPS2828DBVR (same pinout, lower VDD limit). Always verify pin function mapping before substitution.
