The ATA6821-TUS is an integrated automotive-qualified system-basis-chip Power Management IC (PMIC) that provides a range of gate drivers, a buck converter, a linear regulator and integrated diagnostics functions. The ATA6821-TUS is part of the automotive devices business unit of Atmel Systems, and is designed to provide a reliable and efficient power management solution for automotive applications.

ATA6821-TUS belongs to the Gate Drivers category of PMICs, which are all integrated circuits (ICs) that provide the necessary power and control signals for the operation and control of various types of electronic switches, such as MOSFETs, IGBTs and other power semiconductor devices. The specific purpose of gate drivers is to enable the operation of a discrete semiconductor device via an external gate drive circuit. Gate drivers support the power control of a range of external loads, and are commonly used to switch AC and DC loads on and off.

The ATA6821-TUS is designed to provide a reliable and efficient power management solution for automotive applications. It integrates a range of gate drivers that can be used to control power system components such as MOSFETs, IGBTs, and other power semiconductor devices. The ATA6821-TUS gate drivers have been designed to provide clean gate drive signals with low propagation delays and low supply current, allowing them to operate in high-voltage and high-temperature automotive environments.

The ATA6821-TUS gate driver has several key features that make it suitable for automotive applications. First, it features a low-profile packaging that enables it to fit easily into small spaces and tight spaces around the engine compartment. The device\'s integrated buck converter provides efficient power management and its linear regulator can help reduce power dissipation in sensitive power systems. The device also supports integrated diagnostics functions, allowing designers to more easily troubleshoot system faults.

In addition, the ATA6821-TUS has been designed to tolerate high temperatures with an extended range of -60degC to +135degC. It also has a built-in ESD protection circuit to protect against electrostatic discharges up to 4kV. Finally, the device has been designed to meet the requirements of AEC-Q100, Class3 and UL1244 standards.

The ATA6821-TUS is the ideal solution for automotive applications that require robust gate drivers and power management functions, with an extended temperature range and reliable operation in specific conditions. The integrated buck converter and linear regulator provide efficient power management and a range of diagnostic features make troubleshooting easier, while the low-profile packaging makes installation and maintenance simpler.
