Overview
MIC2774 Dual Micro-Power Low Voltage Supervisor General Description The MIC2774 is a dual power supply supervisor that provides undervoltage monitoring, manual reset capability, and power-on reset generation in a compact 5-pin SOT-23 package.
Features include two undervoltage detectors, one fixed and one adjustable, and a choice of reset outputs.
One undervoltage detector compares VDD against a fixed threshold.
Ten factory-programmed thresholds are available.
The second, user-adjustable input is compared against a 300mV reference.
This low reference voltage allows for the monitoring of voltages lower than those supported by previous supervisor ICs.
The reset outputs are asserted at power-on and at any time either voltage drops below the programmed threshold voltage and remains asserted for 140ms (min.
) after they subsequently rise back above the threshold boundaries.
Manual reset functionality can be provided by a switch connected between ground and the /MR input.
A wide choice of vol...
