specifically designed to operate in an automotive or industrial environ-
ment. It uses an internal RC oscillator to drive a digital countdown
circuit for timing periods of typically 2-1/2 to 5 minutes. The
ULQ2436M multiplies the oscillator period by 4064. Internal logic can
automatically cause the timeout to be halved for successive timeouts.

functions. This combination, together with the low-cost 8-pin mini-DIP
plastic package, results in a very economical power timer suitable for a
wide variety of applications.
