Electrical characteristics
The recommended external ballast transistor is the bipolar transistor BCP68 with the gain range of 85 up to 375 (for IC=500mA,
VCE=1V) provided by several suppliers. This includes the gain variations BCP68-10, BCP68-16 and BCP68-25.The most
important parameters for the interoperability with the integrated voltage regulator are the DC current gain (hFE) and the
temperature coefficient of the gain (XTB). While the specified gain range of most BCP68 vendors is the same, there are slight
variations in the temperature coefficient parameter. MPC5643LVoltage regulator operation was simulated against the typical
variation on temperature coefficient and against the specified gain range to have a robust design.
