X5045S8Z-2.7T1

The X5045S8Z-2.7T1 (X5045) is a supervisor device used in power management applications. It is a small, low-power device that provides precision voltage monitoring, overtime protection, and overtemperature protection for power management systems. The X5045 is part of Texas Instruments’ PMIC - Supervisors family, and is used for a variety of applications including battery-powered and portable electronics, notebook, personal digital assistant (PDA) and automotive applications.

In battery-powered and portable electronics applications, the X5045 performs as both a voltage supervisor as well as an overtime protection device. It can detect faults such as voltage drops due to excessive current draw or short circuits. When any of these conditions occur, the X5045 sends an alert to the host system, enabling it to take the necessary steps to protect against damage. The X5045 operates at less than 5 mA of current, making it an ideal choice in applications where power efficiency is paramount.

In notebook, PDA, and automotive applications, the X5045 can detect over-voltage and over-current conditions and send a signal to the power supply to shut down the system. It can also notify the host system to take corrective actions like initiating the shutdown sequence. Additionally, the X5045 provides overtemperature protection, which helps protect the associated components from damage due to excessive heat.

The X5045 works by monitoring two outputs (V1 and V2) as well as two thermal (T1 and T2) sensors. The device will compare the voltage and temperature values to preset thresholds and take corrective action based on the difference. If either the voltage or temperature exceeds the threshold, the X5045 will send the alert to the host system. Depending on the application, the X5045 can be used in either single-voltage or dual-voltage monitoring, as well as overtemperature. Each output can also be configured for either active-low or active-high signal (or both) for added flexibility.

The X5045 supports a wide input voltage range from 2.6 V to 17 V and provides adjustable threshold levels up to 25 V. It can operate in temperatures from -40°C to +125°C, making it suitable for a wide range of applications. Additionally, the X5045 is available in an 8-pin SOT563 package and is RoHS-compliant.

Overall, the X5045 is a highly-integrated and low-power supervisor device. It combines precision voltage monitoring, overtime protection, and overtemperature protection into a single device. It is designed to meet the requirements of power management applications and can be used in a variety of applications including battery-powered and portable electronics, notebook, PDA, and automotive. With its wide input voltage range, adjustable threshold levels, and robust temperature range, the X5045 is an ideal solution for power management applications.
