(1) This product is RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and is suitable for
use in specified lead-free soldering processes. In addition, this product uses package materials that do not contain halogens, including
bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(2) If IN < V_O(OUT-REG), the IN is connected to the OUT pin by a P-FET, (Q1).

DESCRIPTION
I/O Battery input and output.
I Chip enable input (active high)
I Dynamic power-path management set point (account for scale factor)
I Ground input
I Charge input voltage
I/O Charge current set point and precharge and termination set point
I
Charge current set point for USB port. (High = 500 mA, Low = 100 mA) See half-charge current mode
using ISET2.
I Power source selection input (Low for USB mode current limit)
O Output terminal to the system
O Power-good status output (open-drain)
O Charge status output 1 (open-drain)
O Charge status output 2 (open-drain)
I/O
Timer program input programmed by resistor. Disable fast-charge safety timer and termination by tying
TMR to V_REF.
I/O Temperature sense input
