DESCRIPTION
WD TC
RST1 GND ADJ VCC RST2 NC
Clock input pin for watchdog timer. If this IC is only used as a power-on reset timer, this pin is connected to RST1 .
Time setting pin for the reset and watchdog timers. R1 leads to VCC, and C1 leads to GND.
Supplies an NPN transistor open-collector output.
- Generates a reset signal determined by the CR bination connected to the TC pin.
- Supplies reset pulses intermittently if no clock is given to the WD pin.
Grounded
VCC detect voltage (1) adjusting pin. The detection voltage is 4.6V when this pin is grounded ;...
