Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: T J is calculated from the ambient temperature T A and power
dissipation P D according to the following formula:
T J = T A + (P D ? θ JA °C/W)
Note 3: The LTC3559/LTC3559-1 are guaranteed to meet speci?cations
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 4: V CC supply current does not include current through the PROG pin
or any current delivered to the BAT pin. Total input current is equal to this
speci?cation plus 1.00125 ? I BAT where I BAT is the charge current.
Note 5: I C/10 is expressed as a fraction of measured full charge current
with indicated PROG resistor.
Note 6: FB high, regulator not switching.
