Part Number: LM5060-Q1
Other Parts Discussed in Thread: LM5060

Hi,

I have some questions about LM5060-Q1,please find the below queries

1.Is this having reverse polarity and load dump protection feature?

2.What is the maxim high side load can protect by using this IC?

3.Is this is automotive grade and please suggest if their any iC having all protection for high side load and withstand high current up to 80A?

4.I bought Evaluation board of LM50Q1 ,is this EVAL board having reverse polarity  protection?

Regards,

    Hi Rudraprasad,

    LM5060-Q1 is an automotive grade high-side switch and can support reverse polarity, load dump protection. Please refer TI-design http://www.ti.com/tool/TIDA-01167 for more details. Standard EVM is not capable for reverse polarity, load dump protection.

    What is the load ? application use case? and end product ?

    Hi Rakesh,

    Thanks for the swift response,

    We are developing Body control modules for Off highway vehicles ,our module can drive inductive ,capacitive and resistive loads . The load capacity is up to 80A for that we used external mosfet's ,is this LM5060q1 can protect the external loads ? is their any thermal management recommendations ?   

    Thanks & regards,

    Hi Rudraprasad,

    Thanks for the details.

    LM5060-Q1 provides overvoltage, under voltage protection. With parallel FETs, the controller can support higher currents.

    The LM5060 is intended for applications where precise current sensing is not required, but some level of fault protection is needed. Examples are applications where inductance or impedance in the power path limits the current rise in a short circuit condition. Please refer 8.1.5 Overcurrent Fault in the datasheet.
