6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)

		MIN	TYP	MAX	UNIT
V_DD	Supply pin voltage	1.6		6.5	V
V_SET1	SET1 pin voltage	0		6.5	V
C_CWD	Watchdog timing capacitor	0.1 ⁽¹⁾⁽²⁾		1000 ⁽¹⁾⁽²⁾	nF
CWD	Pullup resistor to VDD	9	10	11	kΩ
R_PU	Pullup resistor, RESET and WDO	1	10	100	kΩ
I_RESET	RESET pin current			10	mA
I_WDO	Watchdog output current			10	mA
T_J	Junction temperature	–40		125	°C

(1) Using standard timing with a C_CWD capacitor of 0.1 nF or 1000 nF gives a t_WD(typ) of 0.704 ms or 3.23 seconds, respectively.

(2) Using extended timing with a C_CWD capacitor of 0.1 nF or 1000 nF gives a t_WD(typ) of 62.74 ms or 77.45 seconds, respectively.
