Automotive Half-Amp
High-Side Switch
The MC3399 is a HighâSide 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 âonâ 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 âopeningâ thus protecting the load from the transient voltage for the
duration of the transient. The device automatically reâestablishes 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.
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 5âlead TOâ220 and 16âlead SOIC plastic
packages to facilitate either âthruâholeâ or surface mount use. In addition, it
is specified over a wide ambient operating temperature of â40°C to +125°C
and is ideally suited for industrial and automotive applications where harsh
environments exist.
