Note 1: All devices 100% production tested at T J = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: Resistors were added from OUT to CS+ to aid with the power dissipation during testing.
Note 3: Dropout is measured as follows: Connect a resistor from OUT to CS+. Connect R SENSE = 0.56 Ω from CS+ to CS-. Set V IN =
V OUT +3V (record V OUT as V OUT1 ). Reduce V IN until V OUT = 0.97 x V OUT1 (record as V IN2 and V OUT2 ). Δ V DO = V IN2 - V OUT2 .
Note 4: t ON time includes the delay and the rise time needed for I OUT to reach 90% of its final value. t OFF time is the time needed for
I OUT to drop below 10%. See the Typical Operating Characteristics. t ON and t OFF are tested with 13 Ω from OUT to CS+.
Note 5: TPF/SCL (SCL for MAX16805) and TPN/SDA (SDA for the MAX16805) are I 2 C interface compatible only when the
MAX16805/MAX16806 are the only parts on the bus for production programming.
Note 6: C B is the total bus capacitance.
