TPS1HTC100-Q1: What is the IILIM_ENPS?

Part Number: TPS1HTC100-Q1

Tool/software:

Hello,

The IILIM_ENPS specified in the datasheet 5.5 is the same as ICL_ENPS in Figure 7-6 and 7-7?
If not, what is the IILIM_ENPS?

Best regards,

Hi Hirano-san,

Yes, ILIM_ENPS and ICL_ENPS are the same.

Thanks,

Patrick

Patrick,

Thank you for your response.
But I am a bit confused.
If IILIM_ENPS = ICL_ENPS, why ICL_ENPS(1.2xICL) < ICL_LINPK(1.5 x ICL) in 5.5 Electrical Characteristics, but ICL_ENPS > ICL_LINPK in Figure 7-7? Is this because ICL_LINPK and IILIM_ENPS are specified at different RILIM value in 5.5 Electrical Characteristics?
If so, my customer would like to know ICL_LINPK value at RLIM=10Kohms. Please let them know how much it is at v RLIM=10Kohms.

Best regards,

K.Hirano

Hi Hirano-san,

There is an error in Figure 7.6, ILIM_ENPS should be lower than ICL_LINPK.

ICL_LINPK is for gradual current increases after the device has already been enabled. ILIM_ENPS is for when the device enables into a short, so the current slew rate is much higher. The accuracy of ENPS is higher than accuracy during a gradual short.

The values in the Electrical Characteristics should hold true for all RILIM values.

Thanks,

Patrick

Patrick,

Figure 7-6 is typo?
You are talking about Figure 7-7, right?

Hi Hirano-san,

Yes thanks for catching that, I meant Figure 7-7 has the error.

Thanks,

Patrick
