RE46C104S14F

Sensor And Detector Interfaces Overview

The RE46C104S14F is a piezoelectric horn driver and voltage converter manufactured by Microchip Technology. It operates within a supply voltage range of 4.0V to 8.0V and features a built-in charge pump that generates an output voltage up to 2 x Vdd, allowing outputs to swing from Vss to the boosted level. The device supports a continuous output current of 30mA per driver pin (HornS, HornB, or Vpos) and includes dedicated pins for charge pump enablement and horn activation. It is housed in a 14-pin SOIC package with surface mount mounting and functions reliably across an operating temperature range of 0°C to 50°C.
