标题: RE46C119 DataSheet [打印本页] 作者: admin 时间: 2010-4-17 19:00 标题: RE46C119 DataSheet Voltage Regulator, Voltage Converter and Piezoelectric Horn Driver
The RE46C119 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 6.5uA 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.
