RE46C104S14F

Microchip Tech · Buffers / Drivers · SOIC-14

RE46C104S14F from Microchip Tech, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 N/C unconnected No internal connection.
2 FEED input Feedback control input for a self-oscillating piezoelectric horn (also usable for direct drive), with an input voltage range of -10V to +22V.
3 CAP- passive Charge pump flying capacitor negative terminal, connected to C1 (10uF in the typical application).
4 VSS power_in Ground / negative supply, 0V reference.
5 CAP+ passive Charge pump flying capacitor positive terminal, connected to C1 (10uF in the typical application).
6 HRNEN input Active-high piezo horn enable input, with a logic low of 1.0V max and a logic high of 2.3V min.
7 N/C unconnected No internal connection.
8 N/C unconnected No internal connection.
9 VPOS power_out Charge pump voltage output (typically 8.9V at -16mA, swinging up to 2 x Vdd) that supplies the horn drivers, with a 10uF capacitor C2 and 30mA max continuous output current.
10 HORNB output Horn driver output, swinging from Vss to Vpos, with 30mA max continuous output current.
11 HORNS output Horn driver output, swinging from Vss to Vpos, with 30mA max continuous output current.
12 CPMPEN input Active-high charge pump enable input, which minimizes supply current when low, with a logic low of 1.0V max and a logic high of 2.3V min.
13 VDD power_in Positive supply, operating range 4.0V to 8.0V (absolute maximum -0.5V to +9.0V).
14 N/C unconnected No internal connection.
