Working Principle of MAX6125ESA+T

The MAX6125ESA+T is based on the diode-string topology where each diode connects to a resistor. The voltage at each diode is proportional to the current passing through it. The voltage reference output is then generated by connecting a resistor in series with the diode string and to ground. The voltage varies linearly with the current and the resistor value can be adjusted to manipulate this relationship.

The MAX6125ESA+T operates on a 4V to 35V input voltage range, making it suitable for most applications. It also features a soft-start circuit to limit power-on transients during start-up. The device also has a wide operating temperature range of -40°C to 85°C, which makes it well-suited for use in hostile environments.
