Notes: 1. Max. package power dissipation limits must be respected; low duty cycle pulse techniques are used during test
maintain Tj as close to Tamb as possible.
2.These parameters, although guaranteed, are not 100% tested in production.
3.Parameter measured at trip point of latch with VPIN 2= 0 .
4.Gain defined as:
∆VPIN 1
A=
∆VPIN 3
, 0 ≤ VPIN 3 ≤ 0.8V
5. Adjust VI above the start threshold before setting at 15V.
