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.

3.This device incorporates internal circuit techniques which do not allow the internal junction
temperature to reach destructive temperatures.

4.The thermal resistance case is considered to be a point located near the center of the tab and
plastic body of the TO–220 or a point on one of the heatsink leads (Pins 9 to 16) of the SOP.

5.The SOP thermal information is based on simulation data.

Definition of Currents and Voltages. Positive current flow is defined as conventional current flow into the

device. Negative current flow is defined as current flow out of the device. All voltages are referenced to ground.
Both currents and voltages are specified as absolute (i.e., –10 V is greater than –1.0 V).
