Hello,
I am looking for a sensor power supply device with the following requirements
250-350mA current output
True short to battery shutoff on output (output could be 36v while input could be 0 or 6v)
low dropout, worst case the supply buck could be 5.5v and i need a 5v output supply
The TPS7B4253 seems to meet all of this until i read closer on the short to battery. The fast that it doesnt shutoff for 1mS means i need the diode in front of the in pin (below) which then means I dont have a high enough supply
...
are there any other parts or reference designs to meet my requirements?
