SP32106过压保护芯片（OVP）产品说明书

SP32106 Overvoltage and Overcurrent Protection IC and Li+Charger Front-End Protection IC
The SP32106 devices are highly integrated circuits
designed to provide protection to electronic system
from failures of the charging circuit. The IC
continuously monitors the input voltage, the input
current. In case of an input overvoltage condition, the
IC immediately removes power from the charging
circuit by turning off an internal switch. In the case of
an overcurrent condition, if the overcurrent persists,
switches the pass element OFF after a blanking period.
Additionally, the IC also monitors its own die
temperature and switches off if it becomes too hot.
The input overcurrent threshold is user programmable.
The IC can be controlled by a processor and also
provides status information about fault conditions to
the host.
