Description

The STBC02 is a highly integrated power

management, embedding a linear battery

charger, a 150 mA LDO, 2 SPDT load switches, a

smart reset/watchdog block and a protection

circuit module (PCM) to prevent the battery from

being damaged under fault conditions.

The STBC02 uses a CC/CV algorithm to charge

the battery; the fast charge and the pre-charge

current can be both independently programmed

using dedicated resistors. The termination current

is set by default, being 5% of the programmed

fast charge current, but it can also be fixed to

different values. Likewise, the battery floating

voltage value is programmable and can be set to

a value up to 4.45 V.

The STBC02 also features a charger enable

input to stop the charging process anytime.

The STBC02 is automatically powered off from

the connected battery when the IN pin is not

connected to a valid power source (battery

mode).

A battery under/overtemperature condition can

be detected by using an external circuitry (NTC

thermistor).

The STBC02 draws less than 10 nA from the

connected battery in shipping mode conditions,

so to maximize the battery life during end product

shelf life. The device is available in the Flip Chip

30 package.
