New TI gate driver products enhance overall system efficiency with advanced monitoring and protection features in automotive and industrial applications.

Texas Instruments (TI) today announced a new isolated gate driver that provides advanced monitoring and protection features for high-voltage systems.

Engineers can use the 'UCC21710-Q1', 'UCC21732-Q1', and 'UCC21750' to implement compact, efficient, and high-performance designs in traction inverters, onboard chargers, solar inverters, and motor drives.

These newly unveiled products are the first in the industry to offer integrated sensing capabilities for IGBTs and SiC MOSFETs. This simplifies design and improves system reliability in applications operating up to 1.5 kV _RMS . Integrated components quickly detect overcurrent conditions and safely shut down the system.

The UCC21710-Q1, UCC21732-Q1, and UCC21750 utilize capacitive isolation technology to extend the life of the insulation barrier, achieve higher insulation ratings, faster data rates, and enable high-density packaging.


Key Features of UCC21710-Q1, UCC21732-Q1, and UCC21750
The new isolated gate driver maximizes switching operation and minimizes losses with a high peak drive current of ±10A, and provides rapid system protection with overcurrent detection of 200ns.

The UCC217xx family extends the life of the insulation barrier with capacitive isolation technology and reinforced surge immunity up to 12.8 kV. These devices also provide precision data communication with common-mode transient immunity (CMTI) exceeding 150 V/ns.

TI's new gate driver integrates the buffer and sensor, eliminating the need for separate external components. Additionally, precise temperature, current, and voltage sensing using isolated analog PWM (Pulse Width Modulation) modulation sensors simplifies system-level diagnostics and prevents switch failures.

Along with the three products above, TI also announced the UCC23513, an optical-compatible gate driver for industrial application developers who require enhanced noise immunity and a wider operating temperature range.

The UCC2513 provides 3A of drive current and 5kV _RMS of reinforced safety insulation.

This new gate driver offers a wide junction temperature range of -40°C to +150°C and high common mode transient immunity (CMTI) of more than 100 V/ns, enabling developers to maximize system performance and reliability in motor drives, solar inverters, and power supplies, while overcoming limitations that have been difficult to implement in conventional optocoupler designs.

Additionally, developers are expected to accelerate time to market by leveraging existing design resources with the UCC23513, which is pin-to-pin compatible with opto-isolated gate drivers. Design resources also include a three-phase inverter reference design and optical-mimicking input gate drivers for 200-480 VAC drives.

“High-voltage motor drive and power supply applications face increasingly stringent system robustness requirements,” said Steve Lambouses, vice president of high-voltage power products at TI. “TI’s new gate drivers, which utilize isolation technology, combined with other integrated features, help engineers minimize space and cost and get reliable systems into production more quickly.”

Pre-production samples of the UCC21710-Q1, UCC21732-Q1, UCC21750, and UCC23513 gate drivers are currently available from the TI store. The UCC21710-Q1 and UCC21732-Q1 are priced at $4 each in 1,000-unit quantities, while the UCC21750 is priced at $3.48 and the UCC23513 is priced at $2.08 each.
