Hello,

Unfortunately, I cannot provide the best support in Japanese. Could you please repost in English?

What I gather from what you have written is you are interested in a TI replacement for the FPF2701?

A potential solution could be the TPS27S100 https://www.ti.com/product/TPS27S100

For schematic recommendations please refer to the datasheet and EVM reference schematic located here: https://www.ti.com/tool/TPS27S100AEVM

Best Regards,

Elizabeth

Sorry for asking this question in English.
I would like to use TI's TPS100S2701BRRKT instead of On-Semi's FPF27MPX load switch, but I do not know how to connect the circuit without using an MPU. Please give me a specific schematic and the components to use.
(Conditions)
Input voltage: 24V±5
Output current: 0.5A (typical),
Overcurrent detection: 1A±20
Operation: Output shutdown (latch) after overcurrent detection
Alarm: Alarm (latch) is sent after overcurrent is detected.
Recovery: Recovers by reconnecting power supply
Application: Fan overcurrent detection.
Control: MPU is not used.

Hello,

Although we don't have a dedicated application design for that specific use-case, we do have application examples in the datasheet and the user's guide of the evaluation module for the TPS27S100 device: https://www.ti.com/tool/TPS27S100AEVM

Do note, the TPS27S100 does not latch the output and disable when overcurrent is detected. Instead the TPS27S100 device will clamp the current at the user defined level and hold the current at that level until the current falls below the overcurrent threshold or the device heats up enough to trigger thermal shutdown.

If output shutdown is needed after overcurrent detection, we have devices with a "latch-off" mode which will hold the output current at a set current, and then latch off the device after a delay time. The output in this case will stay latched off regardless of whether the current limit is removed and the output recovers only when IN is toggling. These devices include the TPS1H000-Q1 https://www.ti.com/product/TPS1H000-Q1 and TPS1H200A-Q1 https://www.ti.com/product/TPS1H200A-Q1

Schematic guides for each of these can be found by searching the part number followed by EVM on ti.com.
