Hi Team,
Can you please check and advise with following request?
"
We are planning to make a fuse similar to eFuse (tidu415) in the vehicles we manufacture. In general, we plan this module to basically do the following operations. Apart from these, we will do features such as CAN BUS, analog voltage reading, warnings with microcontrollers. Do you have an integrated module that can do the below features?
- It can output 28V, 50A
- Short-circuit control, in this case, it turns off the output for a certain period of time and then gives the output again.
- Output current drawn as analog value
- Able to turn on/off output when requested
- Reverse battery protection
- “softstart” feature to prevent “inrush current”
"
Thanks in advance
Best Regards

Dear Furkan,
In principle most of the features are covered by the TIDA-00233 circuit. However in your case I would tend to use the circuitry more like in our TIDA-01552 reference design: https://www.ti.com/tool/TIDA-01552.
You need to change the power MOSFETs, the shunt resistor and the components on pin 6 and pin 7 of the LM5069 to meet your application requirements.
Current sensing then needs a current sense amplifier accross the same shunt. Here a selector page to find the right product: https://www.ti.com/amplifier-circuit/current-sense/products.html (or search for current sense amplifier if the link stops working). You might want to look for amplifiers with high common mode voltage like the INA186 or a part with integrated ADC and plenty of monitoring features like INA236 - https://www.ti.com/product/INA236.
