ELECTRICAL CHARACTERISTICS
The q denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VIN1 = 1.5V, VSHDN1 = VIN1, VIN2 = 12V, GATE = 6V, IPOS = INEG = 5V, VSHDN2 = 0.75V unless otherwise noted.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
TJ = TA + (PD • 130°C/W)
Note 3: Switch current limit is guaranteed by design and/or correlation to
static test.
Note 4: The VGS(th) of the external MOSFET must be greater than
3V – VOUT.
