UCC21710-Q1 - 10A Isolated Gate Driver | Texas Instruments
MPN： UCC21710-Q1 ✓ 啟用中UCC21710-Q1 概覽
A gate driver is a power-management IC that converts low-voltage control signals from a microcontroller into high-current pulses to drive the gate of power transistors. In a system hierarchy, the gate driver sits between the controller and the power switch, providing isolation and signal amplification. The UCC21710-Q1 belongs to the isolated gate driver family, which adds galvanic isolation to protect low-voltage control circuitry from high-voltage transients.
Key features include: ±10 A peak source/sink current, 5700 Vrms reinforced isolation, single-channel operation, and input and output side UVLO. It supports overcurrent (OC) and short-circuit detection via shunt sensing, active Miller clamp to prevent spurious turn-on, fault reporting, and isolated analog-to-PWM sensing for temperature or voltage monitoring. These features provide comprehensive protection for SiC and IGBT switching.
The UCC21710-Q1 uses capacitive coupling for signal transfer, achieving high CMTI. It is AEC-Q100 qualified for automotive applications, meeting the reliability demands of HEV/EV traction inverters. The device's short-circuit clamping feature limits gate voltage to slightly above VDD, protecting semiconductors from gate-source/emitter overvoltage breakdown.
Typical applications include HEV/EV traction inverters, solar inverters, industrial motor drives, UPS, wind turbine converters, and railway traction. The high peak current and 1700-V rating allow it to directly drive large IGBT modules and SiC MOSFETs without external buffers. Its isolation enables safe operation in high-voltage DC-link systems.
When designing with this device, ensure proper bias supplies: UCC14240-Q1 is a recommended isolated power supply for the output side. Pay attention to gate loop inductance and maintain adequate PCB spacing for reinforced isolation. The active Miller clamp must be connected to the gate to prevent high dV/dt-induced turn-on.

設計說明
At high switching frequencies, gate drive power dissipation can be significant. Calculate the average gate drive current from total gate charge Qg and frequency: I_avg = Qg * f. The UCC21710-Q1's ±10 A peak current ensures low propagation delay, but the IC self-heating is mainly from quiescent and switching losses. Ensure adequate copper area for the SOIC-16 package thermal pad, and keep the driver close to the gate to minimize parasitic inductance.
For high CMTI performance, minimize stray capacitance between input and output sides. Place the isolation barrier as clean as possible, and use appropriate creepage distances per IEC 60664 for the operating voltage. Keep gate loops short and use a dedicated driver power supply (e.g., UCC14240-Q1) to avoid noise.
Avoid exceeding the absolute maximum ratings of the input and output supply voltages. Maintain proper UVLO threshold margins. Also, the active Miller clamp is essential when using SiC MOSFETs to prevent false turn-on during high dV/dt transitions; ensure the clamp is correctly connected to the gate.
