RE46C104E14F

Sensor And Detector Interfaces Overview

The RE46C104E14F 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 boosts the output voltage up to 2 x Vdd, allowing outputs to swing from Vss to Vpos. The device draws a standby supply current of 500 nA maximum at 5V and a typical operating supply current of 500 µA. It provides continuous output currents of up to 30mA per driver pin and includes dedicated pins for charge pump enable and horn activation.
