NAME
B4P
FUNCTION
Cell 4 Positive Connection. Short B4P to B3P for MAX1924V.
Supply Input. Connect this pin to the top of the battery pack through a diode and a capacitor
(see the
Typical Application Circuit
).
Cell 3 Positive Connection
Internal Connection. Float this pin.
Cell 2 Positive Connection
Internal Connection. Float this pin.
Cell 1 Positive Connection
Internal Connection. Float this pin.
Battery Negative. Connection for the cell 1 negative terminal and the top of the current-sense
resistor R
SENSE
. BN is also chip ground.
Pack Negative. The sense resistor (R
SENSE
) is connected between BN and PKN.
Control Input. Drive CTL low for normal operation. Drive CTL high to turn off the three external
protection MOSFETs.
Shutdown. Drive SHDN low for normal operation. Drive SHDN high to put the device into shutdown
if no charger is present.
Trickle-Charge Driver Output.
TKO
drives the gate of an external P-channel trickle-charge MOSFET
low (on) in normal operation.
Fast-Charge Driver Output.
CGO
drives the gate of an external P-channel fast-charge MOSFET low
(on) in normal operation.
Discharge Driver Output.
DSO
drives the gate of an external P-channel discharge control MOSFET
low (on) in normal operation.
Common Source Connection for MOSFETs. SRC provides the bias for gate drivers
