TPS25200QDRVTQ1

The TPS25200-Q1 device is described as a 5-V eFuse with precision current-limit and overvoltage clamp. It provides robust protection for load and source during overvoltage and overcurrent events. The device is qualified for automotive applications and has AEC-Q100 qualification with specific results. It is an intelligent protected load-switch with a VIN value tolerant to 20V. The device also has a 20-V continuous VIN (Absolute Maximum) rating.

The purpose of the overvoltage clamp feature in the TPS25200-Q1 device is to clamp the output voltage to 5.4V when the input voltage exceeds 7.6V. This feature ensures that the device shuts down in the event of an overvoltage event, preventing damage to the load or the device itself. Additionally, the overvoltage clamp feature helps to protect against slight overvoltage events where the VOUT clamp is engaged over an extended period of time.

The recommended 1% resistor range for RILIM is 36kΩ ≤ RILIM ≤ 1100kΩ to ensure stability of the internal regulation loop. The device allows the user to program the current-limit threshold between 85mA and 2.7A through an external resistor.
