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: MC13892*VK and MC13892*VL in 139, 186 MAPBGA packages.
efficiency advantage and reduced power dissipation in the
pass devices.
VGEN1 nominal output voltage (VNOM as referred in
Table 4) can be 1.20, 1.50, 2.7775, or 3.15 V, and has a
capability of 200 mA. VGEN2 is configurable for 1.20, 1.50,
1.60, 1.80, 2.70, 2.80, 3.00, and 3.15 V, and can supply up to
350 mA.
VGEN3 has an internal PMOS pass FET, which will
support loads up to 50 mA. For higher current capability,
drive for an external PNP is provided. The external PNP
configuration is offered to avoid excess on-chip power
dissipation at high loads and large differential between BP
and output settings. The input pin for the integrated PMOS
option is shared with the base current drive pin for the PNP
option.
This regulator is configurable for nominal output voltages
capability of 200 mA when working with an external PNP.
GENERAL PURPOSE OUTPUTS
The GPO drivers included can provide useful system level
signaling with SPI enabling and programmable Standby
control. Key use cases for GPO outputs include battery pack
thermistor biasing and enabling of peripheral devices, such
as light sensor(s), camera flash, or even supplemental
regulators.
SPI enabling can be used for coordinating GPOs with ADC
conversions for consumption efficiency and desired settling
characteristics.
The GPO1 output is intended to be used for battery
thermistor biasing. For accurate thermistor reading by the
ADC, the output resistance of the GPO1 driver is of
importance.
Finally, a muxing option is included to allow GPO4 to be
configured for a muxed connection into Channel 7 of the GP
ADC. As an example for a dual light sensor application,
Channel 7 can be toggled between the ADIN7
(ADINSEL7=00) and GPO4 (ADINSEL7=11), for convenient
connectivity and monitoring of two sensors. The GPO4 pin is
configured for ADC input mode by default (GPO4ADIN=1), so
that the GPO driver stage is at high impedance at power up.
The GPO4 pin can be configured by software for GPO
operation with GPO4ADIN=0.

PROTECTION FUNCTIONS
SHORT-CIRCUIT PROTECTION
The higher current LDOs, and those most accessible in
product applications, include short-circuit detection and
protection (VVIDEO, VAUDIO, VCAM, VSD, VGEN1,
VGEN2, and VGEN3). The short-circuit protection (SCP)
system includes debounced fault condition detection,
regulator shutdown, and processor interrupt generation to
contain failures and minimize chance of product damage. If a
short-circuit condition is detected, the LDO will be disabled by
resetting its VxEN bit while at the same time an interrupt
SCPI will be generated to flag the fault to the system
processor.
BATTERY MANAGEMENT
The 13892 supports single path and serial path charging.
In single path charging, the device is always supplied from
the battery and therefore always has to be present and valid.
In a serial path charging scheme, the device may operate
directly from the charger while the battery is removed or
deeply discharged. The charger supports charging from a
USB host or a wall charger.
The charger interface provides linear operation via an
integrated DAC at programmable current levels. It
incorporates a standalone trickle charge mode, in case of a
dead battery with dual LED indicator driver. Over-voltage,
short-circuit, and under-voltage detectors are included as
well as charger detection and removal. The charger includes
the necessary circuitry to allow for USB charging and for
reverse supply to an external accessory. The battery
management system also provides a battery presence
detector, and an A to D converter that serves for measuring
the charge current, battery and other supply voltages, as well
as for measuring the battery thermistor and die temperature.
Finally, a system is included for monitoring the current drawn
from, or charged into the main battery for support of a
Coulomb Counter function.
