RE46C104S14TF

Sensor And Detector Interfaces Overview

The RE46C104S14TF 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 supports an operating temperature from 0°C to 50°C. The device features a built-in charge pump that converts the supply voltage to Vpos, allowing outputs to swing from Vss to 2 x Vdd. Standby supply current is specified at 100nA to 500nA depending on voltage conditions, while active supply current reaches up to 500µA. The component utilizes a 14-pin SOIC package with gull-wing leads for surface mount installation.
