I_CHG	Current, BAT pin (Charging)			1.5⁽²⁾	A
T_J	Junction Temperature		–40	125	°C
R_ILIM	Maximum input current programming resistor		1100	8000	Ω
R_ISET	Fast-charge current programming resistor ⁽¹⁾		590	8900	Ω

R_TMR	Timer programming resistor		18	72	kΩ

(1) Use a 1% tolerance resistor for R_ISET to avoid issues with the R_ISET short test when using the maximum charge current setting.

(2) The IC operational charging life is reduced to 20,000 hours, when charging at 1.5A and 125°C. The thermal regulation feature reduces charge current if the IC’s junction temperature reaches 125°C; thus without a good thermal design the maximum programmed charge current may not be reached.
