Part Number: TPS25940-Q1 Other Parts Discussed in Thread: TPS25940
Hi TI team.
During stratup, we have observed that the falut pin is pulled low and then pulled high. For reference, please find the the schematic of TPS25940 below:
And the startup waveform…
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.
Main usage:
1. 12V cut-off, the Out will output 3V.
2. 12V is on, OUT don't output 3V.
Questions:
1. while OVP=12V,VIN=3V…
Part Number: TPS25940-Q1 Other Parts Discussed in Thread: TPS25940 Hi Expert
My customer want to use TPS25940 for Fan protection.
input voltage range is 13.2V~10.8V 12 TYP
output is 12V/1.6A
because the Fan is inductor load. so could you please help to…

Hi Expert
My customer use TPS25940 for their application.
In their test, they found the Vout have status that is pull down to -800mV (AC), but in our datasheet, Vout negative voltage just…
Part Number: TPS25940 What are the differences between the TPS25940A and TPS259401A-Q1? I am having trouble purchasing the TPS25940A and it looks like the TPS259401A-Q1 has limited availability and can be used as a alternative. This will be for pre-production…
Part Number: TPS25940-Q1 Dear team,
1. Can our device work normally when the load current is 100mA he 18mA respectively? If can, what are the current sampling accuracy? What is the resolution?
2. Can our device's IN pin withstand 18V for 1hour, 26.5V…
Part Number: TPS25940-Q1 Hello team,
Based on the datasheet, for transient protection, the TVS is placed across the output to GND and Schottky diode across output to ground, but it seems that Figure 11 shows that TVS is between input to ground. Can you…
