Description

Pull up resistor. To be used when the ST1s connected with a LED

Pull up resistor. Connected between VREF and TH pin

3K3

End of charge current resistor. Used to set the termination current and, as a

“Gas Gauge“ when measuring the voltage across on it.

24K

Fast-charge current resistor. Used to set the charging current

N.M

VPRETH resistor. Used to set programmable pre-charge voltage threshold. If

not mounted, the VPRETHDefault, equal to 2.8V, is set

N.M

IPRETH resistor. Used to set programmable pre-charge voltage threshold below

the default one. If not mounted, the IPRETHDefault, is set

68K

IPRETH resistor. Used to set programmable pre-charge current threshold above

the default one. If not mounted, the IPRETHDefault, is set

470R

If a NTC is not used, a half value of R3 must be mounted to keep the TH

voltage in the correct window

R10

N.M

It has the same function of R6. Moreover, if it is replaced with a short-circuit,

when J5 is closed, the timer is reset (falling edge)

µF

Input capacitor

10nF

TMAX capacitor. Used to set the maximum charging time

µF

Output capacitor

µFVREF filter capacitor. Not mounted
