SUPPLY CONNECTION DIAGRAM
FAST CHARGE TIME AND TOP-OFF TIME ADJUSTMENT
Fast Charge and Top-Off time are controlled by the external resistor R21. Resistors can be selected to support
Fast Charge timeout periods of 0.5hrs to 10hrs. Top-Off charge timeout is one-half of Fast Charge timeout. The
programmed charge time approximately follows the equation:
The evaluation board value of R21 is 100K
CELL TEST VOLTAGE ADJUSTMENT
V
400mV. The programmed CTST value approximately follows the equation:
The evaluation board value of R20 is 27k
CTST
is controlled by the external resistor R20. Resistors can be selected to support CTST values from 32mV to
t = 1.5 x R/1000
