SMM02040C1003FB300 - Brand New IC Chips
-
Description
The SMM02040C1003FB300 is an electronic component model of IC chips, which falls under the product category of IC Chips. It is a highly accurate power supply voltage/current supervisor and monitor with provisions for voltage margining of the monitored supply. This model includes an internal voltage reference to accurately monitor and margin the supply within ±1%. It also has the capability to margin over a wide range from 0.3V to VDD using the internal reference and can read the differential voltage of the supply and voltage drop of the current sense resistor over the I2C bus using an on-chip 10-bit ADC. The margin levels can be set using the I2C serial bus. The model can initiate margining via the I2C bus or by using the MUP or MDN inputs. Once the preprogrammed margin target voltage is reached, it holds the converter at this voltage until receiving an I2C command or de-asserting the margin input pin. When not margining, the TRIM output pin is held in a high impedance state allowing the converter to operate at its nominal set point.
