R&E International
A Subsidiary of Microchip Technology Inc. RE46C109
Voltage Regulator, Voltage Converter and Piezoelectric Horn Driver
Product Specification General Description Features 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 6.5uA 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. Low Quiescent Current
