Built-in protection features, like over-temperature, over-current and active inductive energy clamp protect against short circuits, stalled motors and excessive ambient temperature. Designed to safely handle ordinary overload conditions as well as several extraordinary conditions, including loss of ground, load dump and reverse battery, IPS devices eliminate switch failures with the best efficiency and no addition in part count. Overdesigns for low occurrence situations are minimized.

The double level shifter circuitry that drives the MOSFET in the High-Side Switcher (HSS) provides immunity from large offsets between the logic ground and the load ground and short switching times. Internal slew rate control for turn-on/off and the use of a low noise charge pump means lower EMI. Ground noise generation of less than 10mA is the industry’s lowest figure.
