Battery Removal Detection
The ISL6291 assumes that the thermistor is co-packed with
the battery and is removed together with the battery. When
the ISL6291 sees a voltage of 2.1V or higher on the TEMP
pin, it assumes that the battery is removed. When the battery
is removed, the charger stops and indicates a fault signal. A
new charge cycle starts when a battery is inserted again.
Output Capacitor C
OUT
C
OUT
is typically a 10
μ
F Tantalum capacitor if the charger is
required to operate with no battery attached. For embedded
battery applications, there is no requirement for a capacitor if
the battery is placed close enough to the charger output. It is
recommended, however, that the charger have at least a
0.1uF ceramic capacitor at the charger output for decoupling
purposes.
Input Capacitor C
IN
C
IN
is typically a 10
μ
F Tantalum capacitor or 1
μ
F Ceramic
capacitor.
Stability
The charger is stable with a wide range of external
components, including the typical external components.
