www.ti.com SNLS194A – NOVEMBER 2010 – REVISED MARCH 2013 LM195QML Ultra Reliable Power Transistors
FEATURES 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. 1 2 Internal Thermal Limiting
Greater Than 1.0A Output Current
3.0 ОјA Typical Base Current
500 ns Switching Time
2.0V Saturation
Base Can be Driven up to 40V Without
Damage
Directly Interfaces with CMOS or TTL
100% Electrical Burn-in 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 …
