Its innovative features and capabilities make it an excellent choice for power management in designs requiring higher voltage, current and temperature capabilities.

Overview

The ADP199ACBZ-R7 is a versatile and reliable component designed specificly for use in a variety of applications demanding high power, high temperature, and high voltage. The component features four integrated high-voltage FETs, each of which are independently adjustable with PWM control. The component also features a built in over-voltage protection that prevents catastrophic failures due to high transient voltages. In addition, the component has an adjustable current limiter that avoids damage due to over-current conditions.

The component has four outputs configured for output current regulation, based on the single voltage source of 3.2V. It is designed to provide seamless power delivery with low power dissipation in either linear or switched mode operation. The ADP199ACBZ-R7 features a small 10-pin TDFN package, which allows for a large operating temperature range between -40°C and +140°C. This also makes them suitable for use in harsh industrial environments.

Working Principle

The ADP199ACBZ-R7 is a high-voltage, current-limited, adjustable, high-power switch specifically designed for industrial and portable applications. The device is comprised of four independent, high voltage FETs, each with adjustable current limit protection. By controlling the on-time of the individual FETs, the overall average output current can be regulated. The internal current limit protection prevents damage due to over-current conditions, as the amount of current draw is limited by the on-time. The device also features an adjustable overvoltage protection to prevent catastrophic failures due to high voltage transients.

The device operates by digitally modulating the control pins on each of the FETs. This allows the user to program the device to operate in both linear and switched mode. In linear mode, a PWM signal is used to control the output current by modulating the on-time of the FETs. In switched mode, a single-pulse wider than the on-time is used to regulate the same output current, thus providing a faster response.

The device is able to operate at high input and output voltages, making it suitable for most power management applications. The output current limiter allows for efficient energy management in designs where sustained current, rather than peak power, is required. The ADP199ACBZ-R7 also provides built-in over-temperature protection, and is able to withstand temperatures of up to 140°C. This allows for use in a variety of industrial, automotive and military applications.

Applications

The ADP199ACBZ-R7 is designed to provide a reliable and efficient solution for power management applications demanding high power and high temperature capability. The device is designed to handle input voltages of up to 80V, and output currents of up to 10A. The adjustable current limit and integrated over-voltage protection make it suitable for use in a variety of harsh industrial applications.

The device can be used in a variety of power management applications such as automotive, industrial, military and consumer electronics. It is an ideal solution for applications requiring a reliable, high-efficiency power switch. For example, the device can be used to regulate the power delivery of LED lighting, motor control, and motor drive systems. In addition, the device can be used in medical applications, as well as in portable battery powered devices.

Conclusion

The ADP199ACBZ-R7 is a versatile and reliable power distribution switch, load driver from Analog Devices. It features four independent, high voltage FETs, each with adjustable current limit protection, adjustable over-voltage protection, and integrated over-temperature protection. The device is designed to provide seamless power delivery with a small TDFN package, making it suitable for use in a variety of industrial and consumer applications.
