ISO7721FDWR  

Digital Isolators

The Texas Instruments ISO7721FDWR is a highly integrated single-chip solution for automotive isolated gate drivers. It is designed to meet the demanding requirements of automotive applications, such as electric vehicles (EVs) and hybrid electric vehicles (HEVs), where high efficiency and reliability are critical.

Description:

The ISO7721FDWR is a monolithic half-bridge gate driver with integrated isolation. It features a high-voltage side N-channel MOSFET and a low-voltage side MOSFET, which are connected in a half-bridge configuration. The device also includes an integrated isolation interface, which provides galvanic isolation between the high-voltage and low-voltage sides of the circuit.

Features:

1. Integrated half-bridge gate driver with high-voltage and low-voltage MOSFETs
2. Galvanic isolation between high-voltage and low-voltage sides
3. Wide input voltage range (4.75V to 18V)
4. High output current capability (up to 2.5A)
5. Low propagation delay (60ns maximum)
6. High common-mode transient immunity (CMTI) of 75 kV/µs
7. Small package size (5mm x 7mm QFN)

Applications:

The ISO7721FDWR is well-suited for a variety of automotive applications, including:

1. Electric vehicle (EV) traction inverters
2. Hybrid electric vehicle (HEV) powertrain systems
3. DC-DC converters for battery management systems
4. Motor control applications in automotive accessories (e.g., HVAC, pumps, fans)
5. Industrial motor control systems requiring high efficiency and reliability

In summary, the Texas Instruments ISO7721FDWR is a versatile and efficient single-chip solution for automotive isolated gate drivers. Its integrated half-bridge gate driver, galvanic isolation, and high efficiency make it an ideal choice for a wide range of automotive applications, including EVs, HEVs, and industrial motor control systems.
