NOTES:
1. Operation at battery voltages down to 5.3 volts is guaranteed by design. Operation higher than 18 volts (18 V < V
< 27 V) for up to two
BAT
minutes is permitted if the thermal design of the board prevents reaching the thermal protection temperature limit, T , otherwise the device
sd
will self protect. Typically these requirements will be encountered during jump start operation at T
85 °C and V
< 27 V. Refer to the
amb
BAT
“Thermal Characteristics” section of this data sheet, or application note AN2005 for guidance.
2. This parameter is characterized but not subject to production test.
