FUNCTIONAL DEVICE OPERATION

Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not

available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.

The transient load and line response are specified with the

waveforms as depicted in Figure 10. Note that where the

transient load response refers to the overshoot only, so

excluding the DC shift itself, the transient line response refers

to the sum of both overshoot and DC shift. This is also valid

for the mode transition response.

Notes

55.

3.0 V < BP < 4.65 V, no external loading on VCOREDIG, VCORE, or REFCORE. Extended operation down to UVDET with VCORE

down to UVDET, but no system malfunction.

56.

The core is in On mode when charging, or when the state machine of the IC is not in the Off mode, nor in the power cut mode. Otherwise,

the core is in Off mode.
