Part Number: TPS25946
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…
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…
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…
Part Number: TPS25946 Other Parts Discussed in Thread: TPS25750 , BQ25792 Hello Sir
Please help us to check our schematic, we are using TPS25750+BQ25792 solutions.
But we has some doubts on our power flow, we checked TPS25750 datasheet which has no current…

Part Number: TPS25946 We are using the TPS25946 eFuse with a 12 Volt input.
The PGTH* ppin is connected to 3.3V via a 10K resistor. The eFuse is behaving erratically. Sometimes it would output 12 volts and sometimes. I am attaching a screen shot of the…
