Undervoltage.
If the voltage of the cell drops below undervoltage threshold V
UV
for a period longer than
undervoltage delay t
UVD
, the DS2760 shuts off the charge and discharge FETs, sets the UV flag in the
Protection Register, and enters Sleep Mode.
Overcurrent, Charge Direction.
The voltage difference between the IS1 pin and the IS2 pin (V
IS
= V
IS1
–
V
IS2
) is the filtered voltage drop across the current sense resistor. If V
IS
exceeds overcurrent threshold
V
OC
for a period longer than overcurrent delay t
OCD
, the DS2760 shuts off both external FETs and sets the
COC flag in the Protection Register. The charge current path is not re-established until the voltage on the
PLS pin drops below VDD – V
TP
. The DS2760 provides a test current of value I
TST
from PLS to VSS to
pull PLS down when the offending charge current source has been removed.
Overcurrent, Discharge Direction.
If V
IS
is less than -V
OC
for a period longer than t
OCD
, the DS2760
shuts off the external discharge FET and sets the DOC flag in the Protection Register. The discharge
current path is not re-established until the voltage on PLS rises above VDD - V
TP
. The DS2760 provides
a test current of value I
TST
from VDD to PLS to pull PLS up when the offending low-impedance load has
been removed.
Short Circuit.
If the voltage on the SNS pin with respect to VSS exceeds short circuit threshold V
SC
for
a period longer than short circuit delay t
SCD
, the DS2760 shuts off the external discharge FET and sets the
DOC flag in the Protection Register. The discharge current path is not re-established until the voltage on
PLS rises above VDD - V
TP
. The DS2760 provides a test current of value I
TST
from VDD to PLS to pull
PLS up when the short circuit has been removed.

(1) To allow the device to react quickly to short circuits, detection is actually done on the SNS pin rather
than on the filtered IS1 and IS2 pins. The actual short circuit detect condition is V
