Description
MDC
5
Main DC Input – This input is a voltage monitoring input (and not a high current input). Its purpose is to
determine the presence of the main DC input to provide lockout for the USB power input.
SHDN
6
Shutdown – Pulling this pin high will disable the entire device including the battery discharge path and place
the device in a low power sleep mode. This pin has an internal pull-down.
SUSP
7
Suspend (USB) – Pulling this pin high will prevent current from being drawn from the USB input pin. The rest
of the chip functions are unaffected. This pin has an internal pull-down.
SYS
3
System Power Node – This pin provides power to user system. SYS voltage provided will range from the
battery voltage to the wall adapter and/or USB voltage.
TFB
16
Temperature Feedback – Charging is suspended when the TFB pin falls below 29% (typ) of V
SYS
or rises
above 74% (typ) of V
SYS
.
CHG
and
DONE
pins remain in their prior state during a TFB event. Connecting the
TFB pin to GND disables the TFB function.
USB
4
USB Power Input – USB compliant input.
UCL
8
USB Current Limit – A high logic level will select the high USB current level determined by the programming of
the CUS pin. A low logic level will select a level that is 20% of the high USB current level. This pin has an
internal pull-down.
