Description

The STBC08 is a constant current/constant

voltage charger for single cell Li-Ion batteries. No

external sense resistor or blocking diode is

required.

The STBC08 is designed to work within USB

power specifications. An internal block regulates

the current when the junction temperature

increases, in order to protect the device when it

operates in high power or high ambient

temperature conditions.

The charge voltage is fixed at 4.2V, and current

limitation can be programmed using a single

resistor connected between PROG pin and GND.

The charge cycle is automatically terminated

when the current flowing to the battery is 1/10 of

the programmed value. If the external adaptor is

removed, the STBC08 turns off and a 2µA current

can flow from the battery to the device. The

device can be put into Shutdown Mode, reducing

the supply current to 25µA. The device also has a

charge current monitor, under voltage lockout,

automatic recharge. The charge termination and

input voltage presence are indicated by two

separate status pins.
