Description

The SMM0204503K0 is an electronic component model that falls under the product category of IC Chips. This component is a highly accurate power supply voltage/current supervisor and monitor, designed to provide voltage margining of the monitored supply. It includes an internal voltage reference for accurate monitoring and margining within a ±1% range. The SMM0204503K0 can margin over a wide range from 0.3V to VDD using the internal reference. It also features the ability to read the differential voltage of the supply and voltage drop of the current sense resistor over the I2C bus using a 10-bit ADC.
