ELECTRICAL CHARACTERISTICS (continued)
Vbatt= 12V, Tamb=-40 C to 125 C (unless otherwise specified)
VOLTAGE REGULATOR - Co=220nF - note 2
RESET SUPERVISORY CIRCUIT - note 3
WATCHDOG CIRCUIT
TEMPERATURE OUTPUT
Notes :
1. For proper operation, a 5.6k resistor needs to be connected between OSC and GND.
2. 220nF is the optimized value for the voltage regulator
3. The reset thresholds (Vout increasing and decreasing) are proportional to Vout, (coefficients ki and kd). ki and kd vary in the same direc-
tion with temperature.
4. Watchdog capacitor Cwd should be placed as close as possible to CWD pin.
