Other Parts Discussed in Thread: TPS27081A Hi team,
The recommended input range of TPS27081A is 1V to 8V as datasheet. However it does not specify the RDS(ON) @ -1V VGS. Can anyone provide this spec?
Thank you,
John
Other Parts Discussed in Thread: TPS27081A , TPS22967 Hello
I am working with a super capacitor charging circuit that needs to bring a 0.5F load up over the course of 500ms.
Looking over the information on the datasheet there does not appear to…
Hi,
Thank you for your response.
Yes, I can confirm that the ON/OFF pin is 0V. Also the output voltage is 1.7V when loaded and 0.8V when unloaded.
When the ON/OFF pin is 3.3V, the output voltage is 3.3V. It is normal.
The load current will be…
Other Parts Discussed in Thread: TPS27082L , TPS27081A Hello,
For TPS27082L/TPS27081A, we would like to confirm R1/C1 pin connection:
Q1: In the diagrams C1 is shown somehow directly connected with the internal nodes, however, we figure that it might…
Hi Matt,
This should not change the rise/fall time for the TPS27081A version. These passive components aren't used to 'program' the device. The rise time is primarily determined by how quickly the input (VIN) charges the Output Capacitance (C1) -…

I have an external power source which is connected to TPS27081. When the power is applied to the board it should enable TPS27081A. The MCU1 IO will turn the power off by pulling EN down. Once…
Hello,
In datasheet, it is mentioned that minimum ON/OFF pin voltage required is 1.0V for high level input.
However, we have observed the circuit to turn on with 0.5V on the pin.
What is the minimum voltage, when the device gets turned ON?
Regards…
Hi,
is there any spice model for the TPS27081 available?
I would like to include it in my global simulation.
The application is an active current limiter between a high impedance source and the large bypass capacitor of a switching regulator. Other…
