1.2 Improvements Compared to TDA 4862 and
TDA4863
• Suitable for universal input applications with low THD at low load conditions
• Very low start up current
• Accurate OVR and V_ISENSEmax threshold
• Competition compatible V_CC thresholds
• Enable threshold referred to V_VSENSE
• Compared to TDA4863 a bigger MOS Transistor can be driven (see 2.10)
