SMM02040E1000BB300 - Brand New VISHAY IC Chips
-
Description
The SMM02040E1000BB300 is an electronic component model in the IC Chips category. It is a highly accurate power supply voltage/current supervisor and monitor with provisions for voltage margining of the monitored supply.
Specifications and features
The SMM02040E1000BB300 includes an internal voltage reference for accurate monitoring and margining of the supply to within ±1%. It has the capability to margin over a wide range from 0.3V to VDD using the internal reference. The SMM02040E1000BB300 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 device can initiate margining via the I2C bus or by using the MUP or MDN inputs. Once the preprogrammed margin target voltage is reached, the SMM02040E1000BB300 holds the converter at this voltage until receiving an I2C command or de-asserting the margin input pin. When the SMM02040E1000BB300 is not margining, the TRIM output pin is held in a high impedance state, allowing the converter to operate at its nominal set point.
Application Scenarios
The SMM02040E1000BB300 is suitable for various application scenarios, including:
- In-system test and control of Point-of-Load (POL)
- Power supplies for multi-voltage processors, DSPs, and ASICs
- Routers, servers, storage area networks
