SNAS575A – FEBRUARY 2012 – REVISED MARCH 2013

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of

the device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or

other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating

Conditions indicate conditions at which the device is functional and the device should not be beyond such conditions. All voltages are

measured with respect to the ground pin, unless otherwise specified.

(2)

Human Body Model per MIL-STD-883, Method 3015.7. Machine Model, per JESD22-A115-A. Field-Induced Charge-Device Model, per

JESD22-C101-C.

(3)

For the VSSOP package, the pitch of the solder pads is too narrow for reliable use at higher voltages (VCM >25V). Therefore, it is

strongly advised to add a conformal coating on the PCB assembled with the LMP8278 / LMP8278Q.

(4)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ(MAX), θJA, and the ambient temperature,

TA. The maximum allowable power dissipation PDMAX = (TJ(MAX) - TA)/ θJA or the number given in Absolute Maximum Ratings, whichever

is lower.
