The LTC2921IGN#PBF, part of Linear Technology\'s high-accuracy, low-power, power-supply controllers, monitors, and comparators, is designed for a wide range of applications. These integrated circuits are used for controlling and monitoring battery, AC adaptor, USB, and power-sensitive applications.

The LTC2921IGN#PBF features a high-accuracy, low-power power-supply controller with on-chip integrated system monitoring and analog control loops. It includes two on-chip voltage regulators and one current-sense amplifier. It also provides two analog control loops with output current-channel and voltage-channel, along with a digital control loop with 14-bit PWM output.

The device has an integrated voltage reference and a 14-bit SPI/I2C programmable DAC. The DAC provides full-scale range adjustability. The LTC2921IGN#PBF has a wide input voltage range of 0.8V to 6.7V and an over-voltage shutdown (+7.0V) to protect the system if the input voltage exceeds the specified range. The voltage and current loop controllers both operate over the same 0.8V to 6.7V input range.

The device also offers a range of system-level monitoring capabilities. It includes an integrated temperature monitor and a low-battery detector. The low-battery detector can detect a voltage value below the programmed minimum voltage, and it also measures the current and voltage of the system. The system can be programmed to automatically shutdown if the battery voltage falls below the programmed value or the temperature exceeds the programmed value.

In addition, the LTC2921IGN#PBF features programmable output-protection timers and die temperature selector. The output-protection timer is used to limit the amount of time for the output current in the current-channel, and the die temperature selector provides a way to improve the current-channel accuracy by reducing the area of the die affected by temperature variations.

In addition to its wide range of features, the LTC2921IGN#PBF also provides low power consumption and is designed for hot-swap applications. The integrated circuit is available in a wide range of packages and can be used in a variety of applications, including portable, handheld, and embedded products.

The LTC2921IGN#PBF provides the performance, features, and flexibility to meet the requirements of today’s power-supply controllers, monitors, and comparators. With its low power requirement, wide range of features, and high-accuracy performance, the LTC2921IGN#PBF is an ideal solution for a variety of power-supply-related applications.
