The LTC2992HDE#PBF is an analog-input, digital-output 16-bit power supply controller from Linear Technology Corporation. It provides power supply design engineers with a convenient, easy to use, energy efficient and accurate solution for monitoring multiple power rails and system loads. This device combines precision analog-to-digital conversion and comprehensive system monitoring features in a low power, compact IC package.

The LTC2992HDE is designed to monitor supply and system loads, track power consumption, alert when abnormalities occur, provide fault logging, and make corrections as necessary. It offers an impressive accuracy of 0.1% of the full-scale range, a low power dissipation of under 27µW and is capable of operating from a single 2.7V supply. Additionally, it provides linear temperature compensation and allows for easy programming and fault detection. This device is ideal for monitoring applications requiring high accuracy and low power consumption, such as those found in consumer electronics and other battery powered devices.

The LTC2992HDE#PBF includes an on-chip, high-resolution, 16-bit ADC that provides precision analog-to-digital conversion. Its conversion rate is a fast 8 kHz, enabling it to quickly detect transients or sudden changes in the voltage and current levels of the system\'s power rails. Its 13-bit delta-sigma ADC has a 0.1% of full-scale accuracy, with a temperature coefficient of 0.2%. The device also has two comparators with independent, programmable controllers and two programmable temperature sensors.

The LTC2992HDE#PBF\'s analog inputs are programmable, allowing the user to customize the device to suit the specific application. It can measure both AC and DC voltages and currents, and with the addition of shunts, it can measure and report power. The device can be programmed to shut down the system in case of a fault and can provide accurate power monitoring to a system with an opto-isolated serial port or an I2C interface.

The LTC2992HDE#PBF also includes comprehensive system monitoring features such as brown-out protection, temperature monitoring, and fan-speed monitoring. The brown-out protection monitors the voltage of the power rails, and if the voltage drops below a predetermined level, the controller can reduce the current draw or shut down the system completely. It also includes a programmable shut-down temperature, allowing it to detect when the system has become too hot and shut down, preventing damage to the system components.

The LTC2992HDE#PBF is designed to be used in a variety of power supply and system monitoring designs, such as: servers and workstations; industrial controllers, machines, and automation; medical electronics systems; energy management and green energy systems; battery powered systems. Additionally, it can be used in many automotive monitoring applications, including car engines and batteries.

In conclusion, the LTC2992HDE#PBF is an analog-input, digital-output 16-bit power supply controller designed for precision monitoring and control of power supplies or system loads. It combines power supply design engineers with a convenient, easy to use, energy efficient and accurate solution for a variety of power supply and systems monitoring applications and produces accurate readings on a range of input signals from DC and AC voltages and currents to temperature-based shut down temperatures.
