Working Principles

The TPS2456RHHR integrates a power switch with adjustable current limit functionality. It operates by monitoring the input voltage, output voltage, and current flowing through the device. The adjustable current limit feature allows users to set a threshold beyond which the power switch shuts down to protect the system from excessive current. The device also incorporates overvoltage and undervoltage protection mechanisms to safeguard connected devices. In case of a fault or abnormal condition, the fast response time triggers the fault pin, initiating a shutdown sequence to prevent further damage.
