RE46C109 Datasheet | R - E International

Description The RE46C109 is intended for use in applications where low voltage regulation and a high voltage horn driver are required. The circuit 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 is 6.5u A 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 munication in multiple unit environments. A power good pin monitors the status of the regulator output.
