INHIBIT
The Output Duration Timer can be inhibited from trig-
gering by the voltage level at the INHIBIT input. When this
voltage level exceeds the Inhibit Threshold, the Timer will
be prevented from triggering if it is OFF. If the Timer is
ON, the INHIBIT input is blocked from affecting the Timer.
There is approximately 10% hysteresis between the In-
hibit and Enable thresholds at the INHIBIT input. The LED
output is not affected by the INHIBIT input. An adjustable
Ambient Light Level Inhibit can be implemented by con-
necting a Light Determining Resistor (LDR) network to the
INHIBIT input (See Figures 3 and 4).
DEAD TIME
False turn-ons are prevented from occurring by es-
tablishing a Dead Time between the end of the timeout of
the Output Duration Timer and the retriggering of that
Timer. The state of the DEAD TIME SELECT input de-
termines the Dead Time duration (See Table 2).
OSCILLATOR
For battery operation, an external RC is connected to the
OSCILLATOR input to produce a 50Hz or 60Hz clock. A
30Hz clock can be used to extend timing durations (See
Tables 1 and 2).
DC POWER SUPPLY
V
DD
-Vss is 8V±1V. Typical quiescent current is 250μA
(
TRIAC/RELAY, LED
and
REGULATOR
outputs not loaded).
DC REGULATOR
The LS6501LP includes a Regulator which provides a
nominal +5V to the Differential Amplifier and Window
Comparator and is available as an output to supply the
PIR Sensor.
TRIAC/RELAY OUTPUT
This open drain output turns ON when the Output Dura-
tion Timer is triggered. The output drives a Triac when
the OSCILLATOR input is tied to ground and 50/60Hz is
applied to the AC input (See Figure 3). The output drives
a Relay when the AC input is tied to ground and an RC
network is connected to the OSCILLATOR input (See
Figure 4).
TRIAC DRIVE
(See Figure 3)
With the Output Duration Timer ON and a 2.7V P-P
60Hz signal applied to the AC input, the output produces
a negative-going pulse in each half-cycle delayed a
nominal 1.2ms from the zero crossing. There is no more
than 150μs difference between the zero-crossing delay
of each pulse.
RELAY DRIVE
(See Figure 4)
The output can sink current continously with the Output
Duration Timer ON and the OSCILLATOR input active.
This output can sink current from a relay coil returned to
a positive voltage (V
DD
to 12.5V maximum).
