The
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VCC = 3.3V unless otherwise noted.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: All currents into pins are positive, all voltages are referenced to
GND unless otherwise noted.
Note 3: The internal supply voltage (VCC) is generated from the greater
voltage on the V1 and V2 inputs. VCC = V1 for options D1 and E1.
Note 4: Under typical operating conditions, quiescent current is drawn
from the V1 input. When V2 exceeds V1, V2 supplies the quiescent
current. V1 only for options D1 and E1.
Note 5: The RST output pin on the LTC2903-1 has an internal pull-up to
V2 (for options A1, B1 and C1) of typically 10µA. However, for faster rise
times or for VOH voltages greater than V2, use an external pull-up resistor.
The internal pull-up is connected to V1 for options D1 and E1.
Note 6: For options A1, B1 and C1, the RST pulldown current is derived
from V1, V2 and V3. For options D1 and E1, pulldown strength is derived
from V1.
