PRODUCTION DATA
The regulation voltage is set via the VSET pin to 2s NiMH, the input voltage is 5 V and the charge current is programmed via the ISET pin to 500 mA.
RISET = [KISET / ICHG]
from electrical characteristics table. . . KISET= 300 A?
RISET = [300 A?/0.5 A] = 600 ?
Selecting the closest 1% resistor standard value, use a 604-? resistor between ISET and GND, for an expected ICHG 497 mA.
