Description
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) All voltages are with respect to the potential at the GND pins.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed
performance limits and associated test conditions, see the Electrical Characteristics tables.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office / Distributors for
availability and specifications.
(4) Battery/Charger voltage should be above 6V no more than 10% of the operational lifetime.
(5) Voltage tolerance of LP3952 above 6.0V relies on fact that V_DD1 and V_DD2 (2.8V) are available (ON) at all conditions. If V_DD1 and V_DD2
are not available (ON) at all conditions, Texas Instruments does not guarantee any parameters or reliability for this device.
(6) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T_J=160°C (typ.) and
disengages at T_J=140°C (typ.).
(7) For detailed soldering specifications and information, please refer to Application Note AN1412 : DSBGA Wafer Level Chip Scale
Package
(8) The Human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
