Texas Instruments UC2710T

Overview

UC2710T from Texas Instruments is a high-current, dual-output MOSFET driver in a 5-pin TO-220 package, delivering ±6A source/sink drive capability with 3ns propagation delay and 20ns rise/fall times into 2.2nF load. It operates from 4.7V to 18V supply, features independent VIN/VC rails, under-voltage lockout with hysteresis, and thermal shutdown - designed for driving power MOSFETs in industrial DC-DC converters and motor gate drivers.

For engineers reviewing the UC2710T datasheet, UC2710T pinout, UC2710T application, or UC2710T equivalent, key selection criteria include its 5-pin TO-220 thermal performance (25W case-rated dissipation), inverting/non-inverting dual outputs, UVLO threshold (4.1–4.4V turn-on), and verified 6A transient drive into capacitive loads up to 30nF.

Technical Context

The UC2710T uses a high-speed Schottky bipolar process to deliver fast switching with low output saturation voltage - VO(H) ≤ 4.5V at –6A sink and VO(L) ≤ 4.5V at 6A source. Its dual-input architecture supports independent logic control of inverting and non-inverting outputs, enabling half-bridge or complementary drive configurations without external logic.

Thermal shutdown activates at 165°C junction temperature, and under-voltage lockout includes 0.3V typical hysteresis to prevent oscillation near threshold. The device supports separate VIN (logic bias) and VC (output driver supply) rails, both rated 4.7V–18V, allowing level-shifting between control and power domains.

FAQ

What is the maximum continuous output current rating for UC2710T?

The UC2710T is specified for ±6A peak source/sink current per output. Its steady-state output current is ±500mA, but it delivers 6A pulses into capacitive loads - confirmed by test conditions in the Electrical Characteristics table (IO = –6A and IO = 6A). Thermal limits and PCB heatsinking determine practical continuous current, with 25W case-rated dissipation defining the upper bound under proper mounting.

Does UC2710T support independent control of inverting and non-inverting outputs?

Yes, UC2710T provides two dedicated logic inputs - INV IN (pin 3) and N.I. IN (pin 4) - each controlling one output independently. The truth table confirms that the output state follows either input directly: when INV IN is high, the inverting output goes low; when N.I. IN is high, the non-inverting output goes high. This enables flexible gate drive configurations without external logic.

What is the function of pin 5 on UC2710T?

Pin 5 on UC2710T is the exposed metal tab of the TO-220 package, internally connected to Power GND (pin 2). It serves as both the primary thermal conduction path and the high-current return node for the output stage. When mounted to a heatsink, electrical isolation is required unless the heatsink is referenced to Power GND - otherwise, short-circuit or safety hazards may occur.

How does the under-voltage lockout (UVLO) behave on UC2710T?

The UC2710T UVLO disables outputs when VIN falls below 3.8V (typical turn-off) and re-enables them when VIN rises above 4.1V (typical turn-on), providing 0.3V hysteresis. This prevents oscillatory output behavior during supply ramp-up or brown-out conditions. Both VIN and VC supplies are monitored, and the device remains disabled until both meet threshold requirements.

Can UC2710T drive IGBTs effectively?

Yes, UC2710T can drive IGBTs effectively due to its ±6A peak drive strength, 4.7V–18V VC supply range (supporting standard 15V IGBT gate drive), and low output saturation voltage (≤4.5V at 6A). Its 3ns delay and 20ns edge speeds ensure fast switching, reducing conduction losses - especially valuable in hard-switched IGBT applications like UPS inverters and welding supplies.
