The MC3399 is a High–Side Switch designed to drive loads from the  
positive side of the power supply. The output is controlled by a TTL  
compatible input Enable pin. In the “on” state, the device exhibits very low  
saturation voltages for load currents in excess of 750 mA. The device  
isolates the load from positive or negative going high voltage transients by  
abruptly “opening” thus protecting the load from the transient voltage for the  
duration of the transient. The device automatically re–establishes its original  
operating state following the transient condition.  
The MC3399 is fabricated on a power BIMOS process which combines  
the best features of Bipolar and MOS technologies. The mixed technology  
provides higher gain PNP output devices and results in Power Integrated  
Circuits having substantially reduced quiescent currents.

TECHNICAL DATA  
The device operates over a wide power supply voltage range and can  
withstand voltage transients (positive or negative) of ±100 V. A rugged PNP  
output stage along with active clamp circuitry, output current limit and  
thermal shutdown permit the driving of all types of loads, including inductive.  
The MC3399 is offered in 5–lead TO–220 and 16–lead SOIC plastic  
packages to facilitate either “thru–hole” or surface mount use. In addition, it  
is specified over a wide ambient operating temperature of –40°C to +125°C  
and is ideally suited for industrial and automotive applications where harsh  
environments exist.
