LED1_ON Register (Address: 08h—Default Value: 00h)

LED1_PER Register (Address: 09h—Default Value: 00h)

TPS65013

SLVS517A – AUGUST 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.

B4:B3 CHARGE CURRENT RATE

11 Maximum current set by the external resistor at the ISET pin

10 75% of maximun

01 50% of maximun

00 25% of maximun

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

TPS65013 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

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.
