SGM4157
GENERAL DESCRIPTION
The SGM4157 is a single Low ON-Resistance(1Ω), fast
single-pole double-throw (SPDT) CMOS switch. It is
designed for low operating voltage, high current switching
of speaker output for cell phone applications. The SGM4157
can handle a balanced microphone/speaker/ringtone
generator in a monophone mode. The device contains a
break−before−make (BBM) feature.
The control input, IN, tolerates input drive signals up to
5.5V, independent of supply voltage.
SGM4157 is available in a DFN-6 package.
