Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specified.

denotes the specifications which apply over the full operating
= 12V, unless otherwise noted.
Note 3: An internal clamp limits the DGATE and CPO pins to a minimum of
10V above and a diode below IN. Driving these pins to voltages beyond the
clamp may damage the device.
Note 4: An internal clamp limits the HGATE pin to a minimum of 10V
above and a diode below OUT. Driving this pin to voltages beyond the
clamp may damage the device.
Note 5: Thermal resistance is specified when the exposed pad is soldered
to a 3" × 4.5", four layer, FR4 board.
