Measurement Charge Consumption
(77°F (25°C), 3.0 V)
• 0.8 micro-coulombs
450 kPa Pressure
P = 1.3725 x Po + 100
P = Pressure in kPa
Po = 8 bit scaled output pressure
700 kPa Pressure
P = 2.3529 x Po + 100
P = Pressure in kPa
Po = 8 bit scaled output pressure
1400 kPa Pressure
P = 5.490 x Po
P = Pressure in kPa
Po = 8 bit scaled output pressure
Temperature Maximum
SHTD represents the temperature at which the thermal
shut-down function can be enabled and REL represents
the temperature at which the master reset state is
released.
SHTD
• 239°F (115°C) maximum
• 2.1 to 3.6 V
• Thermal shut-down enabled
REL
• 212°F (100°C) minimum
• 2.1 to 3.6 V
• Master reset release
Voltage Minimum
The voltage at which the Vmin-circuit will return a low
battery voltage status is specified in Vmin:
Temperature
T = To - 50
T = Temperature in °F (°C)
To = 8 bit scaled output temperature
V Battery
V = 0.0108 x Vo + 4
V = V Battery in V
Vo = 8 bit scaled output Vbattery
