General Description
The HT761x is a CMOS LSI chip designed for use in au-
tomatic PIR lamp control. It can operate with a 2-wire
configuration for triac applications or with a 3-wire con-
figuration for relay applications. The chip is equipped
with operational amplifiers, a comparator, timer, a zero
crossing detector, control circuit, a voltage regulator, a
system oscillator, and an output timing oscillator.
Its PIR sensor detects infrared power variations induced
by the motion of a human body and transforms it to a
voltage variation. If the PIR output voltage variation con-
forms to the criteria (refer to the functional description),
the lamp is turned on with an adjustable duration.
The HT761x offers three operating modes (ON, AUTO,
OFF) which can be set through the MODE pin. While the
chip is working in the AUTO mode the user can override
it and switch to the TEST mode, or manual ON mode, or
return to the AUTO mode by switching the power switch.

Description
Negative power supply, ground
RELAY drive output through an external NPN transistor, active high.
TRIAC drive output
The output is a pulse output when active.
Output timing oscillator I/O
It is connected to an external RC to adjust output duration.
System oscillator I/O
OSCS is connected to an external RC to set the system frequency. The
system frequency is at 16kHz for normal application.
Input for AC zero crossing detection
CDS is connected to a CDS voltage divider for daytime/night
auto-detection. Low input to this pin can disable the PIR input. CDS a
Schmitt Trigger input with 5-second input debounce time.
Operating mode selection input:
VDD: Output is always ON
VSS: Output is always OFF
Open: Auto detection
Positive power supply
Regulated voltage output
The output voltage is -4V with respect to VDD.
