DESCRIPTION
The LM195 is a fast, monolithic power integrated
circuit with complete overload protection. This device,
which acts as a high gain power transistor, has
included on the chip, current limiting, power limiting,
and thermal overload protection making it virtually
impossible to destroy from any type of overload.
The inclusion of thermal limiting, a feature not easily
available in discrete designs, provides virtually
absolute protection against overload. Excessive
power dissipation or inadequate heat sinking causes
the thermal limiting circuitry to turn off the device
preventing excessive heating.
The LM195 offers a significant increase in reliability
as well as simplifying power circuitry. In some
applications, where protection is unusually difficult,
such as switching regulators, lamp or solenoid drivers
where normal power dissipation is low, the LM195 is
especially advantageous.
The LM195 is easy to use and only a few precautions
need be observed. Excessive collector to emitter
voltage can destroy the LM195 as with any power
transistor. When the device is used as an emitter
follower with low source impedance, it is necessary to
insert a 5.0k resistor in series with the base lead to
prevent possible emitter follower oscillations.
Although the device is usually stable as an emitter
follower, the resistor eliminates the possibility of
trouble without degrading performance. Finally, since
it has good high frequency response, supply
bypassing is recommended.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
