Electrical Characteristics
(cont’d)
Electrical Characteristics are guaranteed over full junction temperature range (0 to 105
°
C). Ambient temperature must be derated
based on power dissipation and package thermal characteristics. Unless otherwise specified, the conditions of test are V
CC
= 15 V;
BOK = 3 V; OV = 0V; R
T
= 680
; C
T
= 10 nF. To override UVLO, V
CC
should be raised above 18 V prior to test.
