Operating
VIN = 2.4 V
VIN = 0.8 V
VCC = 5.0 V, IREF(OUT) = 90 to 900 µA
3 kΩ ≤ RD = RA + RB ≤ 15 kΩ
VREF(IN) = 1 V
VREF(IN) = 0 V
Operating
CT = 1000 pF, RT = 30 kΩ
Comparator Trip to Source Off
CT = 1000 pF, RT ≥ 15 kΩ, VCC = 5 V
IOUT = ±800 mA, 50% to 90%:

Decreasing VCC
UVLO Enable Volt. - UVLO Disable Volt.
Increasing VCC
VENABLE 1 = VENABLE 2 = 0.8 V
VENABLE 1 = VENABLE 2 = 2.4 V
VENABLE 1 = VENABLE 2 = 0.8 V
