MOTOROLA ANALOG IC DEVICE DATA

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 five–terminal TO–220 has the added feature of having a Fault output

(active low) which will indicate the existence of an over temperature,

over–voltage or current limit condition, including an output short to ground.

When driving a moderate load, the MC3392 performs as an extremely

high gain, low saturation Darlington transistor having CMOS input levels. The

primary advantage of the MC3392 over a Darlington transistor is the

additional protection afforded the device and load when driving difficult or

faulty loads. This device incorporates unique internal current limit and

thermal protection circuitry to safeguard itself and the associated load from

catastrophic failure.

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.
