External temperature monitoring accuracy.
Voltage error at AO when monitoring TEMPI
voltage (measured with TEMPI = 1V)
Internal temperature monitor voltage change
Output at +25°C
From SCL falling edge at data bit 0 of
command to AO output stable within 0.5% of
final value. AO voltage steps from 0V to 2V.

WKUP pin rising edge (WKPOL = 1)
Device wakes up and sets WKUP flag HIGH.
WKUP pin falling edge hystersis
(WKPOL = 1) sets WKUP flag LOW (does not
automatically enter sleep mode)
Resistance from WKUP pin to VSS
(WKPOL = 1)
WKUP pin falling edge (WKPOL = 0)
Device wakes up and sets WKUP flag HIGH.
WKUP pin rising edge hysteresis
(WKPOL = 0) sets WKUP flag LOW (does not
automatically enter sleep mode)
Delay after voltage on WKUP pin crosses the
threshold (rising or falling) before activating
the WKUP bit.
Bit 0 to start of control signal (DFET)
Bit 1 to start of control signal (CFET)
No load on CFET
No load on DFET
DFET voltage = 0 to VCELL3 -1.5V
CFET voltage = 0 to VCELL3 - 1.5V
DFET voltage = VDFET to 1V
VDFET <1V (When turning off the FET)
