Texas Instruments UCC21710QDWRQ1 Environmental and export classification status description

The Texas Instruments UCC21710QDWRQ1 is a high-speed, single-channel gate driver capable of driving N-channel power MOSFETs or IGBTs in high-frequency applications. It is specifically designed for automotive and industrial systems, offering reinforced isolation and robust performance. Functions: 1. Isolation: Provides reinforced isolation between high and low voltage domains to ensure safety and reliability in power system designs. 2. Gate Driver: Enables efficient and precise switching control of power MOSFETs or IGBTs in applications requiring high speed and low power losses. 3. Protection Features: Includes over-current protection, under-voltage lockout, and shoot-through protection to safeguard the components and system against faults. Applications: - Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) - Switch-mode power supplies - Motor drives and inverters - Industrial automation systems Alternative Parts: 1. Silicon Labs SI823H20B-IMR 2. Maxim Integrated MAX14936 3. Infineon Technologies EiceDRIVER™ 2EDL5701H Embedded Modules: 1. Over-Current Protection: Monitors the current flowing through the device and triggers a protection mechanism in case of an overload or short circuit. 2. UVLO (Under-Voltage Lockout): Ensures that the gate driver stays inactive when the supply voltage drops below a specified threshold to prevent improper operation. 3. Shoot-Through Protection: Prevents simultaneous conduction of the high-side and low-side power switches to avoid damaging the devices and improve efficiency. Related Q&A 1.
