OPERATING MODES
Power Down
bq2406x
SLUS689A – JUNE 2006 – REVISED OCTOBER 2006
The typical application diagrams shown here are configured for 750 mA fast charge current, 75 mA pre-charge
current, 5 hour safety timer and 30 min pre-charge timer.
NOTE: Temp window set between 0 ° C and 45 ° C for application w/TS pin.
Figure 16. Application Circuits
The bq2406x family is in a power-down mode when the input power voltage (IN) is below the power-down
threshold V
(PDWN)
. During the power down mode all IC functions are off, and the host commands at the control
pins are not interpreted. The integrated power mosfet connected between IN and OUT pins is off, the status
output pins STAT1 and STAT2 are set to high impedance mode and PG output is set to the high impedance
state.
