suspended and the CHG flag turns on and off at 2Hz.

Either the input power must be cycled or the suspend

mode enabled to clear the fault.

EN1 and EN2 Inputs

EN1 and EN2 are logic inputs that enable the charger

and select the charging current (see Table 1). Drive

EN1 and EN2 high to place the IC in suspend mode.
