BEHAVIOR AT POWER UP AND POWER DOWN
BEHAVIOR AT POWER UP AND POWER DOWN
DEVICE POWER UP
This section describe the device behavior during ramp up,
and ramp down of VSUP/1, and the flexibility offered mainly by
the Crank bit and the two VDD undervoltage reset thresholds.
The figures below illustrate the device behavior during
VSUP/1 ramp up. As the Crank bit is by default set to 0, VDD is
enabled when VSUP/1 is above VSUP TH 1 parameters.
Figure 28. VDD Start-up Versus VSUP/1 Tramp
DEVICE POWER DOWN
The figures below illustrate the device behavior during
VSUP/1 ramp down, based on Crank bit configuration, and
VDD undervoltage reset selection.
Crank Bit Reset (INIT Watchdog Register, Bit 0 =0)
Bit 0 = 0 is the default state for this bit.
During VSUP/1 ramp down, VDD remain ON until device
enters in Reset mode due to a VDD undervoltage condition
(VDD < 4.6 V or VDD < 3.2 V typically, threshold selected by
the SPI). When device is in Reset, if VSUP/1 is below
“VSUP_TH1”, VDD is turned OFF.
Crank Bit Set (INIT Watchdog Register, Bit 0 =1)
The bit 0 is set by SPI write. During VSUP/1 ramp down,
VDD remains ON until device detects a POR and set
BATFAIL. This occurs for a VSUP/1 approx 3.0 V.
