The SGM4062 is a charger front-end integrated circuit
designed to provide protection to Li-ion batteries from
failures of the charging circuitry. The IC continuously
monitors the input voltage and the battery voltage. The
device operates like a linear regulator, maintaining a 5.1V
output with input voltages up to the input over-voltage
threshold (VOVP = 6.8V). During input over-voltage
conditions, the IC immediately turns off the internal pass
FET disconnecting the charging circuitry from the
damaging input source. Additionally, if the battery voltage
rises to unsafe levels while charging, power is removed
from the system. The IC also monitors its die temperature
and switches off if it exceeds 145°C. When the IC is
controlled by a processor, the IC provides status
information about fault conditions to the host.
The SGM4062 is available in Green TDFN-2×2-8L and
MSOP-8 (Exposed Pad) packages and is rated over the
-40°C to +85°C temperature range. SGM4062YDE8G/TR
