Features

1) All outputs except AMP and ANT use a PNP transistor with a low saturation voltage. 2) Output current limit circuit prevents damage to the IC due to short-circuiting. 3) Overvoltage protection circuit provides protection against surges from the ACC or BACKUP input. 4) Compact 12-pin POWER package allows large power dissipation. 5) Thermal protection circuit prevents heat damage to the IC.
