Team,
my customer will either use TMCS1101A4U or TMCS1101A4B in their system:
What will the device measure during these transients?
Will the output be at maximum, eg 10.75A for TMCS1101A4U according to table 5-1 in the datasheet?
Thanks and best regards
franz,
There are several factors here that would dictate the overall output response of the device (wave shape and nature of the transient, input or output BW limitations/filter, etc.), but based on the magnitude and time of the transient, the answer would most likely be yes. Have a look at the output response shown in the DS:
The device updates at constant 4us interval, and begins response a few microseconds after input response. The device would most likely saturate under a condition such as this. I would say based on the conditions described above, the A3U would be a better option here, as both 3.3V and 5V supply would be capable of measuring this transient without fear of saturation:
