Texas Instruments UC2707N

Overview

UC2707N 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 source/sink per channel, operates from 5 V to 40 V supply rails (VIN and VC independently), and features independent inverting/non-inverting inputs with analog/digital shutdown control - used in DC-DC converter gate drive and motor phase control circuits.

For engineers reviewing the UC2707N datasheet, UC2707N pinout, UC2707N application, or UC2707N equivalent, key selection criteria include its 40 ns rise/fall time into 1000 pF load, thermal shutdown at 155°C, latchable analog shutdown capability, and PDIP-16 package compatibility with industrial temperature range (–40°C to +85°C).

Technical Context

The UC2707N integrates two independent totem-pole output stages built on a high-speed Schottky process, each capable of driving power MOSFET gates directly. Its dual-input architecture supports both inverting and non-inverting logic control per channel, enabling flexible PWM or complementary drive configurations.

Shutdown functionality combines digital (Pin 7) and analog (differential stop pins) paths with configurable latching via Pin 3 (Latch Disable). The device maintains separate VIN (logic supply) and VC (driver collector supply) rails, allowing level-shifting operation across wide voltage domains while limiting cross-conduction current spikes to ≤25 ns duration.

Key Specifications

Pinout & Package

UC2707N is housed in a 16-pin plastic dual-in-line package (PDIP-N), with four ground pins (Pins 1, 8, 9, 16) requiring common connection for optimal noise immunity and thermal performance.

FAQ

What is the maximum continuous output current per channel for UC2707N?

The UC2707N supports ±500 mA steady-state output current per channel under normal operating conditions. Its ±1.5 A rating applies only to peak transient current, constrained by thermal limits and PCB layout. Continuous operation above ±500 mA requires careful thermal design, including copper pour and airflow, to avoid exceeding the 155°C thermal shutdown threshold. Derating curves in the UC2707N datasheet specify safe operating area versus ambient temperature and duty cycle.

Does UC2707N support both inverting and non-inverting inputs on the same channel?

Yes, UC2707N provides dedicated inverting (Pins 2, 15) and non-inverting (Pins 4, 13) inputs for each of its two independent channels. This allows simultaneous use of both logic polarities - for example, driving high-side and low-side MOSFETs in a half-bridge with complementary PWM signals. The truth table confirms that each output responds to either input type, and the internal logic ensures no contention between them under normal operation.

Can UC2707N operate with different voltages on VIN and VC pins?

Yes, UC2707N explicitly supports independent supply rails: VIN (Pin 10) powers the logic and input circuitry, while VC (Pin 11) powers the output totem-pole stages. Both can range from 5 V to 40 V, enabling level-shifting applications - such as interfacing a 3.3 V microcontroller (VIN = 3.3 V) to a 24 V gate drive rail (VC = 24 V). This separation prevents logic corruption during high-voltage transients and improves noise immunity in mixed-signal systems.

How does the latch disable function work on UC2707N?

The Latch Disable pin (Pin 3) controls whether analog shutdown events trigger latched or momentary output disable. When Pin 3 is low, an analog shutdown event (via Pins 6/7) forces outputs low and holds them there until VIN is cycled or Pin 3 goes high. When Pin 3 is high, analog shutdown causes only temporary disable - outputs resume normal operation as soon as the analog stop condition clears. This behavior is confirmed in the UC2707N shutdown truth table and internal circuit description.

Is UC2707N RoHS compliant and lead-free?

Yes, UC2707N is RoHS compliant and features NiPdAu (NIPDAU) lead finish, as documented in TI's official packaging addendum. It meets JEDEC Level-2 moisture sensitivity standards and is rated for reflow at 260°C. The "G4" suffix variant (UC2707NG4) explicitly denotes green/RoHS-compliant packaging, but even standard UC2707N units shipped after 2008 comply with RoHS Directive 2011/65/EU.
