RE46C119
Voltage Regulator, Voltage Converter and Piezoelectric Horn Driver
Product Specification
General Description
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.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used
when handling this product. Damage can occur when exposed to extremely high static electrical charges.
