description

The IC is designed to control bidirectional serial data transmission with special standby current-, ambient temperature- and voltage sup- ply requirements. The implemented voltage regulator in combination with the reset function allows a complete power supply for micro - controller including power-on reset and power-down reset. The over temperature protection disables the voltage regulator and the bus driver. After return to normal operation conditions a reset function will be generated. block diagram
