The ULQ2436M is a rugged, long-duration countdown timer

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.

conventional linear bipolar devices for the oscillator and output power

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.

The Darlington-connected output driver is capable of switching

loads up to 400 mA.
