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 my affect device reliability.

2.

All voltages are with respect to network ground terminal.

3.

The ACE45677D are guaranteed to meet performance specifications from 0°C to 70°C. Specifications over

the

–40°C to 85°C operating temperature range are assured by design, characterization and correlation with

statistical process controls.

4.

The human body model is a 100

pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine

model is a 200pF capacitor discharged directly into each pin.

5.

If VCC is between UVLO and 4.5V, 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 (VFLOAT less than in the specification), but will

not be overcharged (VFLOAT will not exceed specification).

6.

The thermal regulation feature r

educes charge current if the IC’s junction temperature reaches 125°C; thus,

without a good thermal design the maximum programmed charge current may not be reached.

7.

Use a 1% tolerance metal film resistor for RPROG to avoid issues with the RPROG short test when using the

maximum charge current setting.
