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.
I2L technology is used for the countdown and logic circuitry and
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.
