Li-ion/Li Polymer Linear Battery Charger

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 COUT

COUT is typically a 10µF 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 CIN

CIN is typically a 10µF Tantalum capacitor or 1µF Ceramic

capacitor.

Stability

The charger is stable with a wide range of external

components, including the typical external components.
