PM6613N

Operating description

The PM6613N supports 7 SMBus commands as listed in Table 10.

4.2

ACFET/RBFET and BATFET system power selectors

The PM6613N integrates 2 charge pumps to drive nMOS selectors for ACFET/RBFET and

BATFET. At reset condition, the PM6613N internal circuitry controls the RBFET turn-on, to

avoid inrush current flowing from ADP (adapter) to SYS (system). The BATFET selector

connects (disconnects) the battery from the system. At reset condition, the BATFET selector

is controlled by the internal circuitry. During a charging process, if the adapter is

disconnected, the PM6613N stops any charge operation and remains in sleep mode: if the

BSE is set, the PM6613N connects the battery to the system. If the SOVR bit is set, the

internal circuitry can be disabled: the nMOS selectors can be manually controlled changing

the ARED and BED bits respectively.
