RE46C119
RE46C119 is a Horn driver w/Vreg, interconnect, low batt det, BO det for Smoke Detectors and CO Detectors
制造商:Microchip
产品信息
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.
