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 V
DD
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 voltage thresholds provides for a variety of
supply voltages and tolerances. Hysteresis is included to
prevent chattering due to noise. Typical supply current is a
low 3.5µA.

What is the principle of this circuit?
[size=6]My analysis is that the single-ended to differential circuit is a differential circuit. The signal only goes from mic-p, and there is no signal from mic-m. It is a pseudo differential. I don't...

Burning is successful, but startup is unsuccessful
The message printed by the serial port is as shown in the figure above, but when starting up, many TWID TIMEOUT messages appear. Has anyone seen this phenomenon before? Please solve it! Thank you....

Is this weather going to be unbearable?
The day before yesterday, the sun was shining brightly, and the atmosphere was full of summer heat. I felt like wearing a coat would evaporate, and I seemed to have the urge to wear short sleeves. But...
