All devices are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed by design.
V
BAT
refers to the voltage across the battery terminals; V
BAT
= V
GND
– V
BATN
.
Output voltage must not exceed V
BB_OUT
- V
BATN
= 5.0V.
Actual value may be limited by the lower of the capability of the source (battery) or the maximum input power of the MAX20310.
Timing must be fast enough to prevent the device from entering sleep mode due to bus low for period > t
SLEEP
.
f
SCL
must meet the minimum clock low time plus the rise/fall times.
The maximum t
HD:DAT
has to be met only if the device does not stretch the low period (t
LOW
) of the SCL signal.
The device internally provides a hold time of at least 100ns for the SDA signal (referred to the V
IH_MIN
of the SCL signal) to
bridge the undefined region of the falling edge of SCL.
