MAX6377UR23+T

The MAX6377UR23+T is an ultra-low-power voltage detector in 3 pin SOT23 package. It is an ultra-low-power circuit used for monitoring battery, power supply and regulated system voltages. Each detector contains a precision bandgap reference, comparator and internally trimmed resistors that set specified trip threshold voltages. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 2.5V to 5V. It performs a single function which assert an output signal whenever the VCC supply voltage falls below a preset threshold. The devices are differentiated by their output logic configurations and preset threshold voltages. It is used in precision battery monitoring, load switching/power sequencing, power supply monitoring in digital/analogue systems and portable/battery powered equipment.

• Vcc operating range from 1.2V to 5.5V
