Part Number: TPS25946 Tool/software: Hi,
I'm looking for an over-current protection device for DC motor application where the output voltage is between 0V-30V (no negative voltage/reverse current). can I use one of the e-fuses such TPS25946 for this…

Hello,
We are using the TPS25946 e-fuse. The input voltage is 12V. I am attaching a screen shot of the circuit.
Initially, we were using a 0.01 UF capacitor at the input of DVdt. We could observe that occasionally (often), the…
Hi Gary,
I got confused from this.
Gary Allbee said: Ideally I require a bidrectional fuse with voltage and current limitation in both directions with option for reverse current blocking
Now, I understand that you need eFuse with bidirectional current…
Hi Benny,
Benny Wang said: Regarding the issue you asked about, occasionally the voltage may slightly exceed the current measured result of 28.1V, sometimes reaching 28.5V. However, it cannot be guaranteed that these occurrences are precisely spaced every…
Part Number: TPS25946 Other Parts Discussed in Thread: TPS25947 Tool/software: Hi team,
I found TPS25946 and 25947 has same back to back FET in block diagram, but TPS25946 can support current flow in both directions , while TPS25947 only support IN to…
Part Number: TPS25946 I found the following description on the datasheet page 25.
What does this mean?
When I short the output pin to GND, sometimes this device can't out voltage but sometimes can out,
even if I toggle the EN/UVLO pin.
What does…
Part Number: TPS25946 Hi Team, We are observing an issue with the TPS259461L. We are using it as switch for controlling output power to a daughter board. The setup: Input power is derived from a DC power supply - set at 7.4V with 10A limit. The output power…
I have made test with additional Input_Capacitor and here are my conclusions:
Cin=1uF
TPS is still blocking with shortcircuit or DC motor as a load.
Shortcircuit as a load:
DC motor as a load:
Cin=10uF
TPS is blocking only with DC motor as a load…
