DOZE CIRCUIT: (Figures 6A and 6B)
The Doze circuits shown generate a slow clock (0.04Hz) at
the DZ terminal. If the UP/DOWN inputs (Figures 5A and
5B) are not activated, the Sense node of the Doze circuit
sits at a logic high level.
A momentary pressing of the
Doze switch sets the SR flip-flop, enabling the oscillator.
Every negative transition of the clock (DZ terminal) causes
the lamp brightness to be reduced by equal increments, un-
til eventurally the lamp is shut- off.
When the lamp is off, the oscillator has no further effect on
the dimmer circuit. When the lamp is turned on again by
activating the UP input, the SR flip-flop is reset and the DZ
clock is turned off.
When the Doze circuit is used, the connection between
DOZE input (Pin 2) and Vss (Pin 1), as shown in Figures
5A and 5B, should be removed.

(1) Last intensity achieved before turn off is stored as memory intensity.
(2) On (Dim Up) varies intensity towards maximum and stops there.
(3) Off (Dim Down) varies intensity towards minimum and stops there.
(4) Auto-dimming period controlled by RC components and intensity level when Auto-Dim is activated.
(5) Last intensity achieved before Auto-Dim started is stored as memory intensity.
