DS2762 High-Precision Li+ Battery Monitor With Alerts
register, and enters sleep mode. The DS2762 provides a current-limited (I RC ) recovery charge path from PLS to
V DD to gently charge severely depleted cells. The recovery path is enabled when 0 ￡ V DD < 3V (typ). Once V DD
reaches 3V (typ), the DS2762 returns to normal operation, awaiting connection of a charger to turn on the charge
FET and pull out of 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 DS2762 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 V DD - V TP . The
DS2762 provides a test current of value I TST from PLS to V SS to pull PLS down to detect the removal of the
offending charge current source.
Overcurrent, Discharge Direction. If V IS is less than -V OC for a period longer than t OCD , the DS2762 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 V DD - V TP . The DS2762 provides a test current of value I TST from
V DD to PLS to pull PLS up to detect the removal of the offending low-impedance load.
Short Circuit. If the voltage on the SNS pin with respect to V SS exceeds short-circuit threshold V SC for a period
longer than short-circuit delay t SCD , the DS2762 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 V DD - V TP .
The DS2762 provides a test current of value I TST from V DD to PLS to pull PLS up to detect the removal of the short
circuit.

NOTE 1: TO ALLOW THE DEVICE TO REACT QUICKLY TO SHORT CIRCUITS, DETECTION OCCURS ON THE SNS PIN RATHER THAN ON THE
FILTERED IS1 AND IS2 PINS. THE ACTUAL SHORT-CIRCUIT DETECT CONDITION IS V SNS > V SC .
Summary. All of the protection conditions described above are ORed together to affect the CC and DC outputs.
DC = (Undervoltage) or (Overcurrent, Either Direction) or (Short Circuit) or (Protection Register Bit DE = 0)
or (Sleep Mode)
CC = (Overvoltage) or (Undervoltage) or (Overcurrent, Charge Direction) or (Protection Register bit CE = 0)
or (Sleep Mode)
