Product details
Overview
UC3710DWTR from Texas Instruments is a high-current dual-output FET driver IC designed to interface low-level logic with power MOSFETs in switching power supplies and motor drives. It delivers ±6A source/sink drive capability, features 3ns propagation delay, 20ns rise/fall times into 2.2nF, operates from 4.7V to 18V, and provides both inverting and non-inverting outputs for flexible gate control in half-bridge or synchronous rectifier topologies.
For engineers reviewing the UC3710DWTR datasheet, UC3710DWTR pinout, UC3710DWTR application, or UC3710DWTR equivalent, key selection criteria include its 16-pin SOIC-wide package, 0°C to +70°C industrial temperature range, thermal shutdown protection, under-voltage lockout with hysteresis, and compatibility with high-speed switching designs requiring precise timing and robust drive strength.
Technical Context
The UC3710DWTR uses a high-speed Schottky bipolar process to achieve fast switching performance while maintaining robust output drive. Its totem-pole output stage supports simultaneous sourcing and sinking of ≥6A peak current, with independent VIN and VC supply rails enabling flexible biasing in isolated or multi-rail systems.
It integrates under-voltage lockout (UVLO) with 0.3V typical hysteresis and thermal shutdown at 165°C, ensuring safe operation during fault conditions. The device supports dual digital inputs - INV and N.I. - allowing direct logic-level control of complementary outputs without external inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Drive Strength | ±6A peak source/sink current ensures reliable turn-on/turn-off of large gate capacitance MOSFETs in high-power converters. |
| Propagation Delay | 3ns typical delay enables precise timing alignment in high-frequency (>1MHz) switching applications. |
| Rise/Fall Time | 20ns into 2.2nF load minimizes switching losses and EMI in hard-switched topologies. |
| Supply Voltage Range | 4.7V to 18V on both VIN and VC rails allows operation across wide input voltage ranges and mixed-supply systems. |
| Operating Temperature | 0°C to +70°C ambient rating suits commercial and industrial power electronics environments. |
| UVLO Threshold | 4.1V to 4.4V rising-edge threshold with 0.3V hysteresis prevents erratic operation during brown-out conditions. |
| Thermal Shutdown | 165°C junction temperature cutoff protects against sustained overload or poor heatsinking. |
Pinout & Package
The UC3710DWTR is housed in a 16-pin SOIC-wide (DW) package with exposed thermal pad, optimized for surface-mount assembly and moderate power dissipation. Pin numbering follows standard SOIC convention with pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Ground / Power Return Paths | Multiple GND pins (Logic Gnd, Pwr Gnd) reduce ground bounce and improve noise immunity in high-dI/dt switching. |
| 9 | Inverting Input (INV) | Digital input controlling inverted output polarity; compatible with TTL/CMOS logic levels. |
| 10 | Non-Inverting Input (N.I.) | Digital input controlling non-inverted output polarity; enables dual-input logic flexibility. |
| 11 | Output (OUT) | High-current totem-pole output driving MOSFET gates; capable of ±6A transient current. |
| 12 | VIN Supply | Logic-side supply rail (4.7–18V); powers internal logic and input buffers. |
| 13 | VC Supply | Driver-side supply rail (4.7–18V); independently biased to optimize gate drive voltage swing. |
| 14 | Thermal Shutdown Sense | Internally connected node monitoring die temperature; triggers shutdown at 165°C. |
| 15, 16 | UVLO Reference / Bias | Internal UVLO comparator reference path; tied to VIN for hysteresis-based supply monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Totem-pole output stage | Delivers true ±6A peak drive without external boost components, reducing gate drive loop inductance. |
| Dual logic inputs (INV/N.I.) | Enables direct implementation of AND/OR logic functions at the driver level, eliminating need for external gates. |
| Independent VIN and VC supplies | Allows separation of logic and power domains-critical for isolated DC-DC controllers and bootstrap gate drivers. |
| Under-voltage lockout with hysteresis | Prevents partial turn-on during startup or brown-out by holding outputs low until stable supply is confirmed. |
| Thermal shutdown protection | Self-protects against sustained overcurrent or inadequate heatsinking without external sensing circuitry. |
Applications
| Switch-Mode Power Supplies | Motor Drive Half-Bridge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current FET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC37322D | Single-output, 9A peak drive, 14-pin SOIC, no UVLO hysteresis, 4.5–15V operation. | Lacks dual-input logic flexibility and independent VC supply; suited for simpler single-FET drive. | Choose when higher peak current is needed but dual-output logic and wide supply range are not required. |
| LM5113SDX | High-side/low-side dual driver, 5A per channel, 16-pin WSON, integrated bootstrap diode, 5–14V VC range. | Designed specifically for floating high-side drive; lacks inverting/non-inverting input pairing. | Prefer for bootstrap-based half-bridge designs where compact footprint and integrated diode reduce BOM count. |
Compared with UCC37322D and LM5113SDX, the UC3710DWTR uniquely combines dual-input logic control, independent VIN/VC rails, and ±6A drive in a 16-pin SOIC package-making it optimal for flexible, high-reliability gate drive in fixed-supply industrial power stages.

FAQ
What is the maximum allowable supply voltage for UC3710DWTR?
The UC3710DWTR supports absolute maximum supply voltages of 20V on both VIN and VC pins, though recommended operating range is 4.7V to 18V. Exceeding 18V may degrade long-term reliability or trigger internal protection circuits. Always maintain <20V to avoid permanent damage, as specified in Absolute Maximum Ratings.
Does UC3710DWTR support both inverting and non-inverting outputs simultaneously?
Yes, the UC3710DWTR provides one output pin (pin 11) whose state follows either the INV input (pin 9) or N.I. input (pin 10), depending on external connection. The truth table confirms that OUT = INV when N.I. is held high, and OUT = N.I. when INV is held low-enabling configurable logic mapping without external gates.
What thermal protection mechanism does UC3710DWTR implement?
The UC3710DWTR incorporates junction temperature sensing with automatic thermal shutdown activation at 165°C. Once triggered, the output is forced low and remains latched off until die temperature falls below the hysteresis threshold (~155°C). This protects both the UC3710DWTR and downstream MOSFETs during overload or cooling failure.
Is UC3710DWTR pin-compatible with other members of the UCx710 family?
No, UC3710DWTR is not pin-compatible with UC1710J (8-pin CDIP) or UC2710N (8-pin PDIP). Its 16-pin SOIC-wide (DW) footprint is unique within the family. While functional behavior is consistent, PCB layout must be redesigned for UC3710DWTR due to differing pin count, spacing, and thermal pad requirements.
What is the minimum load capacitance for which UC3710DWTR guarantees 20ns rise/fall time?
The 20ns rise/fall time specification for UC3710DWTR is guaranteed only for a 2.2nF capacitive load, as tested and documented in Electrical Characteristics tables. With larger loads like 30nF, rise/fall times increase significantly (up to 150ns), so design margins must account for this degradation in high-Ciss MOSFET applications.
