Applies to
The switch of the 32 kHz clock system from XTAL to
internal clock causes missing pulses in the 32 kHz
clock, which lowers the frequency of the switcher PLL.
The buck switcher then drops in output voltage.
If UVBUS is present before the battery, the switcher
acts as soon as the battery is present, instead of
waiting until the power up sequence is initialized.This
overshoot can tie the switcher output to BP for a short
period.
The reverse supply mode is being shut off if the
temperature increases over approximately 90°C.
The buck current limit does not function properly, there
is no max current limit, and current limit may engage
before the rated load current of the switcher.
Activating the SWLED boost regulator can cause
REFCORE perturbations which cause the part to
shutdown.
When hot plugging a high voltage charger the BP
node can spike up to 7.5V and greater.

Impact
Freescale Semiconductor
Place a 10 MOhm resistor in parallel
with the crystal.

Migrate to revised device:

MC13892AJVK
MC13892BJVK
Place a 100 kOhm pull-down resistor on
VCORE. Note: This workaround is only
needed if the UVBUS supply is present
before the battery. It is not needed if
UVBUS is not used.

Do not use reverse supply mode if the
device is being used at this
temperature.

Immediately after power up firmware
should disable the current limit by
setting the SWILIMB SPI bit = 1.
Application needs to provide current
limit protection circuitry either in the
battery or as a pre regulated supply to
BP.
Do not use SWLEDOUT boost supply to
provide power for backlight LED sinks,
use external supply to generate boost
voltage required for backlight LED's.
Use a overvoltage protection IC on the
charger input
