Automotiv/Industrial Ambient Operating Temperature Range1, 2
1 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.
