The Texas Instruments LTC2901-3IGN#PBF offer analog and digital monitoring in a single package, ideal for a wide range of power management and supervisor applications. The device monitors two or three power supplies or inputs and provides comparator thresholds, windowed thresholds and interrupts. The device also features watchdog timers, power good outputs and selectable digital delay, making it an excellent choice for three- and four-phase, dual-channel monitoring. Additionally, an external power-on reset pin is available for applications with more complex power sequencing requirements.

As part of the supervisory and power management integrated circuit (PMIC) family, the LTC2901-3IGN#PBF is a versatile monitoring and protection integrated circuit featuring both analog and digital components. The device provides multiple detectors, including power good outputs, digital input and output pins and an adjustable digital delay. This unique combination of features makes it an ideal choice for a variety of applications including power rail monitoring, system supervisor applications, circuit protection and fault detection.

When used as a power supply supervisor, the device can detect out of range voltages and signal over voltage, under voltage and overtemperature events. It can also be used as an error detector to detect open fuse or short circuit conditions, and can be used to indicate low battery conditions in backup system scenarios. Additionally, the device can be used to monitor over/under currents and enable an adjustable safety shutdown feature for applications where overcurrent protection is required.

The LTC2901-3IGN#PBF is designed to operate over a wide input voltage range, typically from 4V to 36V, and its power-on reset (POR) and power good outputs are designed to operate over a wide range of temperatures. The device delivers superior accuracy and specification under harsh operating conditions, allowing users to design systems with reliable operation over a wide temperature range. This high performance and reliability, combined with its small size and low power consumption, makes it an ideal solution for power management and monitoring.

The LTC2901-3IGN#PBF features an adjustable digital delay and comparator thresholds, as well as window thresholds for high and low input detection. The device can be programmed to either monitor the input voltage or input current in order to detect a fault condition. Additionally, the device has an external power-on reset (POR) pin, which can be used to control power sequencing events or to provide an external reset for the entire system.

The LTC2901-3IGN#PBF also includes watchdog timer outputs which are ideal for applications requiring continuous monitoring of a system\'s general health. The watchdog timer can be programmed to generate an interrupt when a device is operating incorrectly or when a system is operating outside of the specified parameters. This interrupt can be used to trigger a system reset, allowing the system to complete a safe shutdown or restart to alleviate the fault problem.

In summary, the LTC2901-3IGN#PBF is a versatile IC designed for a variety of monitoring and protection applications, including power rail monitoring, system supervisor applications, circuit protection and fault detection. Its features include a wide input voltage range, adjustable digital delay, comparator thresholds, window thresholds and a watchdog timer. Its small size and low power consumption make it an excellent choice for power management and monitoring applications.
