SLVS501A – FEBRUARY 2004 – REVISED JANUARY 2005
Bit 5 - Fast charge timer + taper timer enabled:
0 = fast charge timer disabled (default), CHSTATUS < 3 >= status of the taper detect comparator output.
1 = enables the fast charge timer and taper timer. CHSTATUS < 3 >= status of the taper timer.
Bit 4, Bit 3 - MSB/LSB Charge current:
Used to set the constant current in the current regulation phase.

Bit 2 - USB 100 mA / 500 mA:
0 = sets the USB charging current to max 100 mA.
1 = sets the USB charging current to max 500 mA. B2 is ignored if B1 = 0.
Bit 1 - USB charge allowed:
0 = prevents any charging from the USB input.
1 = charging from the USB input is allowed.
Bit 0 - Charge enable:
0 = charging is not allowed.
1 = charger is free to charge from either of the two input sources. If both sources are present and valid, the
TPS65011 charges from the AC pin source.

The LED1_ON and LED1_PER registers can be used to take control of the PG open drain output normally
controlled by the charger.
Bit 7 - PG1: Control of the PG pin is determined by PG1 and PG2 according to the table under LED1_PER
register
Bit 6 - BIT 0 - LED1_ON<6:0> are used to program the on-time of the open drain output transistor at the PG pin.
The minimum on-time is typically 10 ms and one LSB corresponds to a 10-ms step change in the on-time.
