    thermal shutdown in ic desgn

    the principle goes like this.. a fixed reference base voltage (lower than Vbe) is applied in an off-state NPN transistor (biased by the resistor). when temp rises, transistor Vbe goes down, thereby, triggering the transistor when it reached a Vbe lower than the reference voltage.. when the...
