Piezoelectric Horn Driver
The piezoelectric horn driver provides circuitry to drive
a 3-pin piezoelectric horn/annunciator. These horns
contain a ceramic element that bends or expands when
a voltage is applied, generating a single tone capable
of reaching 100dB. They can be used in a wide variety
of applications requiring audible alerts such as theft,
intrusion proximity or fire alarms, chemical sensors,
door sensors, and safety monitors.
The three-terminal piezoelectric horn is connected to
the horn silver (HORNS), horn brass (HORNB), and
feedback (FEED) pins, plus a dedicated ground for the
horn driver (GNDHORN). The MAXQ3210 is designed to
drive any industry-standard piezoelectric horn, allowing
the designer maximum flexibility and lowest overall sys-
tem cost. A single bit (HRNE) enables or disables the
horn output, and software can toggle the bit to produce
sounds of varying durations and patterns.
