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: 5. Adjust VI above the start threshold before setting at 15V. A= ∆VPIN 1 ∆VPIN 3 , 0 ≤ VPIN 3 ≤ 0.8V |
