I would like to know the leakage current between VS to GND under the following conditions.
VS=7.5V
OUT=OPEN
V(IN)=5V
V(DIAG_EN)=5V
CL=47kΩ to GND

Hi Omata,
Checking on this with the team. I will get back to you soon.
Thanks,

Hi Omata,
VS to GND should not be connected. Based off of the stated conditions, the device is in an open-load condition. Leakage current typically refers to when the device is in the off state. What parameter are you exactly asking for or where is your path of concern?
Thanks,

I would like to know the current consumption of VS in an open load state.
The TPS1H100 datasheet states the following:
If the off-state diagnostic is required in the system, the typical standby current is around 1 mA with
DIAG_EN high.
Does this apply?
How about in the case of TPS1H000?
Hi Omata,
That would not apply because it is for the off-state and previously you stated that IN = 5V so it is in the on-state. What version of the TPS1H100-Q1 do you have? For the TPS1H000-Q1, please see below.
Thanks,

I'm using version A.
I want to detect open load on another circuit.
Because I want to detect open and short circuits separately
Therefore,I would like to know the current consumption of VS in an open load state.
Hi Omata,
For the TPS1H100-Q1, A version, please see below from the datasheet.
You can use external circuitry for the TPSxHxxxA family of smart high side switches to distinguish between open load and short to battery faults.
Please see sections 3.2 Open Load Fault and 3.3 Short to Battery Fault in the following application note on how to do so.
