The SG3546 is an undervoltage sensing
circuit specifically designed for use as
a reset controller in 3.3V
microprocessor-based applications. Its
micropower operation makes this
device ideal for portable applications
where extended battery life is required.
The device offers a 1.2V temperature
compensated bandgap reference, a

precision comparator with hysteresis
and a high-current open collector
output. This device operates from 1 to
10V input supply and drains <10μA in
the non-fault condition.
The SG3546 is available in an 8-pin
150mil SOIC package or a 3-pin TO-92
package and is rated for an ambient
temperature of 0°C to 70°C.
