Product details
Overview
UC2707Q from Texas Instruments is a dual-channel high-speed power MOSFET driver IC designed for interfacing low-level logic with high-power switching stages. It delivers ±1.5 A peak output current per channel, operates from 5 V to 40 V supply rails (VIN and VC independently), and features independent inverting/non-inverting inputs, analog/digital shutdown with latch control, and thermal shutdown protection - used in DC-DC converters and motor gate drive circuits.
For engineers reviewing the UC2707Q datasheet, UC2707Q pinout, UC2707Q application, or UC2707Q equivalent, this page provides verified technical context, real-world timing behavior (40 ns rise/fall into 1000 pF), package-specific thermal limits, truth-table–validated input logic mapping, and confirmed alternatives for industrial power stage design.
Technical Context
The UC2707Q integrates two independent totem-pole output stages built on a high-speed Schottky process, each capable of sourcing or sinking up to 1.5 A transient current while maintaining <2.5 V output saturation at –500 mA. Its dual-input architecture supports both inverting and non-inverting logic control per channel, with propagation delays under 60 ns (10%–90%) and cross-conduction spike duration limited to 25 ns during output transitions.
Shutdown functionality combines analog differential stop inputs (100–160 mV threshold) and digital shutdown pin override, with latching behavior controlled by the Latch Disable pin (0.8–2.2 V threshold). Thermal shutdown activates at 155°C, and analog stop delay is 180 ns - enabling precise timing-critical fault response in isolated half-bridge drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current (peak) | ±1.5 A per channel - sufficient to directly drive power MOSFET gates without external buffers in ≤100 kHz switching applications |
| Rise/fall time | 40 ns into 1000 pF - enables clean edge integrity for fast-switching topologies like synchronous buck or push-pull converters |
| Supply voltage range | 5 V to 40 V (VIN and VC independent) - supports wide-input industrial DC supplies and battery-backed systems |
| Analog shutdown threshold | 100–160 mV differential - allows precision current-sense fault detection without external amplification |
| Thermal shutdown | 155°C - protects against sustained overloads in enclosed power modules without requiring external thermal sensors |
| Digital input levels | High ≥2.2 V, Low ≤0.8 V - compatible with TTL and CMOS logic families across temperature range |
| Operating temperature | –40°C to +85°C - qualified for industrial ambient environments including motor control cabinets and power supplies |
Pinout & Package
UC2707Q is supplied in a 16-pin SOIC (DW) package with gull-wing leads, RoHS-compliant NiPdAu finish, and moisture sensitivity level (MSL) 2–260°C–1 year - suitable for standard reflow assembly. Pin 1 is located in quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INV A) | Inverting input, Channel A | Drives Channel A output low when high; logic inversion enables direct PWM inversion without external gate |
| 2 (N.I. A) | Non-inverting input, Channel A | Drives Channel A output high when high; supports standard logic-level gate drive |
| 3 (LD) | Latch Disable | Low enables latched analog shutdown; high disables latching - critical for fail-safe reset behavior |
| 4 (GND) | Ground (4 pins total) | All four GND pins must be connected together to minimize ground bounce and ensure stable reference |
| 5 (OUT A) | Channel A output | Totem-pole driver capable of ±1.5 A - connects directly to MOSFET gate with minimal external components |
| 6 (VC) | Collector supply | Independent high-side supply rail (5–40 V); decoupling required near pin to suppress switching noise |
| 7 (SHDN) | Digital shutdown input/output | Hard logic high forces immediate shutdown; overrides analog stop and latch disable - used for system-level fault interlock |
| 8 (VIN) | Input supply | Logic-side supply (5–40 V); powers internal logic and input buffers - may differ from VC in isolated designs |
| 9 (VIN) | Input supply (duplicate) | Second VIN connection for improved supply routing; must connect to same rail as Pin 8 |
| 10 (OUT B) | Channel B output | Identical to OUT A - enables dual independent gate drives for half-bridge or dual-MOSFET configurations |
| 11 (INV B) | Inverting input, Channel B | Independent inversion path for Channel B - supports complementary drive with dead-time insertion |
| 12 (N.I. B) | Non-inverting input, Channel B | Enables parallel or mirrored logic control of second channel without external inverters |
| 13 (ANALOG STOP+) | Analog shutdown positive input | Differential comparator input for precision fault detection - referenced to ANALOG STOP– (Pin 14) |
| 14 (ANALOG STOP–) | Analog shutdown negative input | Completes differential pair; 100–160 mV window defines shutdown activation threshold |
| 15 (VC) | Collector supply (duplicate) | Second VC connection for low-inductance high-side supply routing - must tie to same rail as Pin 6 |
| 16 (GND) | Ground (4 pins total) | Part of quad-GND structure - all four GND pins (4, 16, and two unmarked) must be shorted on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent totem-pole outputs | Each channel sources/sinks up to 1.5 A peak - eliminates need for discrete buffer transistors in medium-power gate drive |
| Programmable analog/digital shutdown | Combines 180 ns analog stop delay with 50 ns digital SHDN response - supports layered fault handling (e.g., overcurrent + overtemperature) |
| Configurable latching behavior | Latch Disable pin (Pin 3) selects between momentary and latched shutdown - essential for safety-critical reset protocols |
| Low quiescent current | 12–15 mA VIN supply current at 40 V - reduces standby power in always-on industrial controllers |
| High-speed switching | 40 ns rise/fall into 1000 pF with <25 ns cross-conduction spike - minimizes shoot-through risk in half-bridge topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel power driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UC3707N | Same pinout and electrical specs, but rated for 0°C to +70°C ambient - lacks extended industrial temperature range | Suitable for commercial-grade power supplies where ambient stays below 70°C | Select UC3707N only if operating temperature never exceeds 70°C; UC2707Q preferred for full industrial range |
| UCC27524ADRV | Modern 5-A dual driver with 15-V max supply, no analog shutdown, and 12 ns propagation - higher speed but narrower voltage range | Better for high-frequency SMPS (>1 MHz) with 3.3/5/12 V logic, not for 40 V industrial bus interfaces | Choose UCC27524ADRV when speed >100 ns matters more than 40 V tolerance or analog fault detection |
Compared with UC3707N, UC2707Q adds –40°C capability and tighter thermal shutdown consistency; versus UCC27524ADRV, UC2707Q retains analog shutdown, wider supply range, and legacy compatibility - making it optimal for ruggedized, fault-aware industrial gate drive.

FAQ
What is the maximum continuous output current rating for UC2707Q?
The UC2707Q supports ±500 mA steady-state output current per channel, with ±1.5 A peak transient capability - limited by power dissipation and thermal design. At TA = 25°C in SOIC package, continuous operation above ±500 mA requires careful heatsinking and derating per the datasheet thermal curves.
Does UC2707Q support both inverting and non-inverting logic inputs on each channel?
Yes, UC2707Q provides dedicated INV and N.I. inputs for each channel (Pins 1/2 for A, Pins 11/12 for B), allowing independent configuration - e.g., one channel can use inverting logic while the other uses non-inverting, enabling flexible PWM and dead-time control without external gates.
How does the analog shutdown function work in UC2707Q?
The UC2707Q analog shutdown uses differential inputs (Pins 13 and 14) with a 100–160 mV threshold window; when the voltage difference exceeds this, it triggers shutdown unless overridden by Latch Disable status or digital SHDN pin. Delay is 180 ns, supporting fast current-fault response in power stages.
Can UC2707Q operate with different voltages on VIN and VC pins?
Yes, UC2707Q allows independent supply rails: VIN (Pins 8/9) powers logic and input buffers (5–40 V), while VC (Pins 6/15) powers output stages (5–40 V). This enables level-shifting in isolated topologies - e.g., 5 V logic control with 24 V gate drive - provided grounds are properly referenced.
What is the thermal shutdown temperature threshold for UC2707Q?
The UC2707Q activates thermal shutdown at 155°C junction temperature, as specified in the Electrical Characteristics table. This protection is internal and non-latching - recovery occurs automatically once junction temperature falls below hysteresis threshold, unless latched via analog shutdown and Latch Disable pin.
