TEST CONDITION
0.5V ≤ V(IMON) ≤ 0.9V
0.5V ≤ V(IMON) ≤ 0.9V
Note 1
V(VDRP) – V(DACBUFF) = 1.67 mV
With FB = 0V, adjust V(SS/DEL) until
EAOUT drives high
Relative to Charge Voltage, SS/DEL rising
Relative to Charge Voltage, SS/DEL falling
Note 1
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5 V < V(VOSEN+) < 1.6V
-0.3V ≤ VOSEN- ≤ 0.3V, All VID Codes
V(VCCL) – V(VO)
V(VCCL)=7V
Measure V(FB) – V(VSETPT). Note 2
