Product details
Overview
UCC27536DBVR 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 V to 35 V wide VDD operating range. It features inverting input logic, enable pin with TTL-compatible threshold, and rail-to-rail output swing - deployed in SiC FET converters and motor control inverters where asymmetric turn-on/turn-off control is required.
For engineers reviewing the UCC27536DBVR datasheet, UCC27536DBVR pinout, UCC27536DBVR application, or UCC27536DBVR equivalent, key selection criteria include its inverting-input configuration, split-output capability (not present), fixed 2.5-A/2.5-A symmetrical drive, EN-enabled operation, and −5 V DC input tolerance below ground - critical for robust gate driving in noisy power stage environments.
Technical Context
The UCC27536DBVR implements an inverting-input architecture with dedicated EN pin, enabling precise timing control in half-bridge or synchronous buck topologies. Its output stage delivers matched 2.5-A source and 2.5-A sink currents into capacitive loads, supporting fast switching of low-Qg SiC MOSFETs up to 100 kHz.
Internal undervoltage lockout (UVLO) activates at 8.9 V (typical turn-on) with 0.7 V hysteresis, ensuring clean output state during power-up. Input pins tolerate −5 V DC below GND, and the device holds output low during floating inputs or UVLO conditions - eliminating unintended turn-on in system start-up or fault recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 10 V to 35 V - supports wide-input industrial and renewable energy DC bus voltages without external regulation |
| Peak Output Current | 2.5 A source / 2.5 A sink - enables direct drive of medium-power SiC MOSFETs (Qg ≤ 40 nC) without external buffers |
| Propagation Delay | 17 ns typical - minimizes timing skew in high-frequency PWM control loops (e.g., >200 kHz resonant converters) |
| Rise/Fall Time | 15 ns / 7 ns typical (1.8 nF load) - ensures sharp edge fidelity for minimizing switching losses in hard-switched topologies |
| Input Threshold | TTL/CMOS compatible (1.0 V low / 2.0 V high) - interoperable with microcontrollers, DSPs, and isolated gate drivers without level-shifting |
| UVLO Threshold | 8.9 V turn-on / 8.2 V turn-off (0.7 V hysteresis) - prevents erratic operation during brown-out or soft-start sequences |
| Operating Temp | −40°C to +140°C junction - qualified for under-hood automotive, solar inverter, and industrial motor drive environments |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, surface-mount, lead-free, RoHS-compliant. Thermal resistance RθJA = 178.3°C/W (JEDEC high-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Pull low to disable output; open or high enables driver - provides system-level safety shutdown independent of signal path |
| 2 - GND | Power and signal reference | Common return for VDD, inputs, and outputs; must be low-inductance connection to minimize ground bounce |
| 3 - IN− | Inverting logic input | Active-high input yields active-low output - simplifies interface with PWM controllers requiring inverted gate signals |
| 4 - OUT | Driver output | Single-pin 2.5-A source / 2.5-A sink output - connects directly to gate of power switch; requires external RC network for slew rate tuning |
| 5 - VDD | Bias supply input | Accepts 10–35 V; internal UVLO ensures output remains low until stable bias is established |
Key Features
| Feature | Design Value |
|---|---|
| Inverting input logic | Eliminates need for external inverter stage when interfacing with non-inverting PWM controllers - reduces BOM count and layout area |
| TTL/CMOS input compatibility | Enables direct connection to FPGA GPIO, MCU timers, or digital isolators without level translation - simplifies digital control integration |
| −5 V DC input tolerance | Prevents latch-up or damage during ground transients in high-dI/dt power stages - improves reliability in motor drive and inverter applications |
| Output low on floating inputs | Guarantees safe default state during MCU reset, communication loss, or unpowered logic - prevents shoot-through in bridge configurations |
| 17 ns propagation delay | Reduces timing margin requirements in high-frequency LLC or phase-shifted full-bridge designs - supports tighter PWM resolution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27537DBVR | Same SOT-23-5 package, but non-inverting input and 5-A sink current | Better suited for low-side IGBT driving where strong turn-off is prioritized over matched rise/fall | Select UCC27537DBVR if inverting logic is unnecessary and higher sink current is needed for Miller clamping |
| TPS2828DBVR | Pin-to-pin compatible per datasheet; 2-A source / 4-A sink, 12 V max VDD | Limited to lower-voltage applications (<12 V bias); not rated for 35 V VDD or −40°C to +140°C | Choose TPS2828DBVR only for cost-sensitive, low-voltage (<12 V) legacy designs where full UCC27536DBVR specs are unused |
Compared with UCC27537DBVR and TPS2828DBVR, the UCC27536DBVR uniquely combines inverting logic, symmetrical 2.5-A drive, and 35-V VDD tolerance - making it optimal for new SiC/GaN designs requiring precise timing control and wide-bias flexibility.

FAQ
What is the input logic configuration of the UCC27536DBVR?
The UCC27536DBVR features an inverting input (IN− pin): a logic-high input produces a logic-low output, and vice versa. This eliminates the need for external inverters when interfacing with standard non-inverting PWM controllers. The EN pin operates independently with TTL-compatible thresholds, allowing system-level enable/disable control without affecting signal polarity. This configuration is confirmed in the Device Comparison Table and Pin Functions section of the SLUSBA7G datasheet.
Does the UCC27536DBVR support split output (OUTH/OUTL) configuration?
No, the UCC27536DBVR does not support split output. It uses a single-output (OUT) pin delivering 2.5-A source and 2.5-A sink current - unlike UCC27531 or UCC27538 which offer separate OUTH and OUTL pins. The SOT-23-5 package and pinout (EN, GND, IN−, OUT, VDD) confirm this single-output architecture. Split-output functionality is exclusive to 6-pin variants in the UCC2753x family.
What is the maximum allowable VDD voltage for continuous operation of the UCC27536DBVR?
The UCC27536DBVR supports continuous VDD operation from 10 V to 35 V, as specified in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the SLUSBA7G datasheet. Exceeding 35 V risks permanent damage. The 35-V rating enables direct use with 24-V and 32-V industrial bus rails and high-voltage solar string inputs without external regulators.
How does the UCC27536DBVR behave when the EN pin is left floating?
When the EN pin is left floating, the UCC27536DBVR output remains low - a defined safe state per the datasheet's Pin Functions description: "Pull EN to GND to disable output, pull it high or leave open to enable output." This behavior is enforced by internal circuitry and ensures no unintended gate turn-on during power-up, MCU reset, or signal loss - critical for preventing shoot-through in half-bridge configurations.
Is the UCC27536DBVR pin-compatible with the TPS2828DBVR?
Yes, the UCC27536DBVR is explicitly stated as pin-to-pin compatible with the TPS2828DBVR per the UCC2753x datasheet (SLUSBA7G, Feature list). Both use SOT-23-5 (DBV) packaging with identical pin assignments (EN, GND, IN−, OUT, VDD). However, key differences exist: UCC27536DBVR supports 35-V VDD and −40°C to +140°C operation, while TPS2828DBVR is limited to 12-V VDD and commercial temperature range.
