In most portable systems designs, battery and display specifications limits the operating range to well within these
specifications. Most battery manufacturers recommend enabling battery charge only when the ambient temperature is between
0°C and 40°C. To ensure that battery charging does not occur outside the recommended temperature range, the system
ambient temperature may be monitored by connecting a thermistor to the LRADC0 or LRADC6 pin on the i.MX28.
For applications powered by external 5V only, the Maximum Ambient Operating Temperature specified in
achieved. Application developers need to do the worst-case power consumption estimation, and then calculate the Total
On-chip Power Dissipation based on the equations specified in note 3 below.

Tested with only the i.MX28 processor loading the MX28 PMU output rails during start up. With external loadings (for example,
one DDR2 device and SD Card/NAND Flash), MX28 PMU was tested at BATT/DCDC_BATT > 3.30 V.
When the real-time clock is enabled, the chip consumes additional current in the OFF state to keep the crystal oscillator and
the real-time clock running.
