Part Number: TPS25940-Q1 We have a question regarding TPS25940-Q1 eFUSE latching version.
We have a normal slow-blow fuse between the eFUSE GND and global GND to disable the eFUSE in case of any internal short.
However, we are experiencing an issue - when…
Part Number: TPS25940-Q1 Dear expert,
Customer want to use 100Hz (50% duty cycle ) PWM signal to control EN pin. Is it OK?
C(dVdT) = 0.8 nF
tON(dly)+tOFF(dly) =220+2=222 uS which is far below 100Hz (10ms). It should be OK, right?
Part Number: TPS25940-Q1 Hello team,
Aimed at one usage that OVP connect to 12V battery and VIN connect to 3V back up battery.
