HORN DRIVER W/BO DET

The RE46C317/18 are CMOS piezoelectric horn driverICs with built-in boost converter. They are intended foruse in 3V battery or battery-backed applications. Thecircuits feature a boost converter and a driver circuitsuitable for driving a piezoelectric horn.The RE46C317/18 are compatible with the RE46C117device and offer lower standby current.The RE46C317 has three valid states of Horn Enable(tri-state, low and high), while the RE46C318 has onlytwo valid states, low and high.
