TPS7B7701-Q1: TPS7B7701: Voltage vs current curve over Temperature for internal Push pull Circuit.

Part Number: TPS7B7701-Q1

HI Team,

We need VOL vs IOL  curve over Temperature and similarly VOH and IOH over temperature, We basically looking for electrical Characteristics   of VOH, VOL, IOH,IOL, VIH,VIL to find the response over temperature change.

We want to know the MIN ,MAX ON resistance for the internal push pull circuit to understand over temperature change for this LDO IC TPS7B7701. 

Please provide more information for this.

something similar to below graph

    Hi Ghana,

    There might be a misunderstanding here regarding how LDOs are specified because we do not characterize the capabilities the way that microcontroller IO pins are characterized. If you can help me understand the kind of information you are looking for I can help you out, but I am not sure what you are asking for. Additionally, there are no push-pulls in this device, unless you are referring to the pass FET along with its reverse protection complementary FET. What are you trying to accomplish? 

    Regards,

    Nick

    Hi Nick,

    I Would like to reframe the question asked.

    We are basically looking for internal pull-ups , pull downs and ROH,ROL,RIH and RILs temperature variation graph. for the pins

    Example: We know EN pin is input pin and there is internal Pull down and pull up(High impedance ). We need the temperature change graph for this resistor or input Voltage/current variation.

    Similarly for below Pins,

    EN ,LIM,SENSE,SENSE_EN, ERR,SENSE SEL 

    we are trying to perform Worst case for each pin.

    Hi Ghana,

    We unfortunately do not collect data in the form that you want for our LDO devices. However, the EC table specs have a lot of the information you are looking for already - see I_I(EN) and I_lkg (in both the current sense and current limit section as well as the interface circuitry section). They are not as granular as what you are requesting, but they are spec'd over the full temperature range so they represent worst-case. 

    Please let me know if this answers your question.

    Regards,

    Nick
