L7554 Low-Power SLIC
Recommended Operating Conditions
Electrical Characteristics
Minimum and maximum values are testing requirements. Typical values are characteristic of the device and are the
result of engineering evaluations. Typical values are for information purposes only and are not part of the testing
requirements. Minimum and maximum values apply across the entire temperature range (–40
°
C to +85
°
C) and
the entire battery range unless otherwise specified. Typical is defined as 25
°
C, V
CC
= 5.0 V, V
