Original question:

LM5106: LM5106 HS Undershoot to around -6.6V

LM5106:Undershoot of HS

Part Number: LM5106

HS端子がVssより低い電圧にアンダーシュートした場合、どのような問題が起こるのでしょうか。
データシートに記載されているHSの絶対最大定格ではMin側は規定されておらず、ICが破損する恐れはないと考えていますが、正しいでしょうか。

    Hello,

    The negative transient capability is discussed in the note under the Recommended Operating Conditions of the LM5106 datasheet:

    HS can go below VSS, but must not be more than 15V below VDD. With a minimum VDD = 8V, this would give a minimum HS = -7V.

    Best,
