This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltages are DC and with respect to VSS.

This data is based on using the JEDEC High-K board and the exposed die pad is connected to a copper pad on the board. This is

connected to the ground plane by a 2x3 via matrix.

(1)

Pins VCC and IN must be tied together.

(2)

If Vin is between UVLO and 4.35V, and above the battery voltage, then the IC is active (can deliver some charge to the battery), but the

IC will have limited or degraded performance (some functions may not meet data sheet specifications). The battery may be

undercharged (VO(reg) less than in the specification), but will not be overcharged (VO(reg) will not exceed specification).
