Low Side Protected Switch

The MC3392 is a low side protected switch designed for use in harsh automotive applications which require the capability of handling high voltages attributed to load and field dump transients, in addition to reverse and double battery conditions. The three terminal TO–220 is intended to replace power Darlington transistors in new and existing switching applications when taking into account the CMOS input levels required by the MC3392. It offers improved functionality and ruggedness over power Darlingtons while retaining the same package and pin configuration, and can be used as a replacement in many applications using the industry standard TIP100/101 NPN power Darlington transistor.

The MC3392 is available in a three and five–lead TO–220 package; the five–lead having the added diagnostic feature. The full featured MC3392 is also available in a 16 pin wide body SOIC plastic power package.
