SYMBOL
DESCRIPTION
1
CT
tWDM, tWDR, tPR adjustment pin.
tWDM, tWDR, tPR times are dependent on the value of external CT capacitor used. See Figure 18 (Timing
Diagram) for definition of tWDM, tWDR, tPR times.
2
RESET
Reset HIGH output pin.
3
CLK
Clock input pin from logic system for watchdog timer.
4
GND
Circuit ground.
5
VCC
Power supply pin for circuit.
6
WDC
Watchdog timer control pin.
The watchdog timer is enabled when this pin is unconnected, and disabled when this pin is connected to
ground.
7
VS
Detection threshold adjustment pin.
The detection threshold can be increased by connecting this pin to VCC with a pull-up resistor. The detection
threshold can be decreased by connecting this pin to ground with a pull-down resistor.
8
RESET
Reset LOW output pin.
