Description

The RE46C119 is intended for use in applications where low voltage regulation and a high voltage horn driver are required. The circuit RE46C119 features a voltage boost converter/regulator and driver circuit suitable for driving a piezoelectric horn. The horn enable pin activates the boost converter and horn driver circuit. Supply current RE46C119 is 6.5uA maximum when the boost regulator and horn driver are not in use. A 3V regulator is also provided for microprocessor voltage regulation. Low battery detection and signaling are also available. Interconnect pins are provided to allow communication in multiple unit environments. A power good pin monitors the status of the regulator output.
