LM43602-Q1: VIN Maximum Ratings

Peiheng Liu

Part Number: LM43602-Q1

Hi,

I am looking into the datasheet of LM43602-Q1. Maximum rating of VIN is 42V under 'max duty cycle 0.01% of 10000 hours' note. What do the 'duty cycle' and '10000 hours' referred to? Thanks for your help!

Sam,

Great thanks for your input!

From my understanding, maximum duty cycle refers to an repetitive transient event that does not damage LM43602-Q1. Would there be explicit requirements about the Vin maximum pulse wide, as a non-repetitive event goes between 36V and 42V without damaging the device?

Peiheng,

We test our datasheet to a time <500msec at a duty cycle of 0.01%.
