SMM150
Description
The SMM150 is capable of margining the DC output voltage of LDOs or DC/DC converters that use a trim/adjust pin.
Key Features
- Capable of margining supplies with trim inputs using either positive or negative trim pin control
- Wide Margin range from 0.3V to VDD using internal reference
- 10-bit ADC readout of supply voltage over I2C bus
- Margining Controlled Via: I2C mand .. Input Pins (MUP, MDN)
- Two programmable general purpose sensor inputs (P1/2) – UV/OV with FAULT Output
- Programmable glitch filter (P1/2)
- Programmable internal VREF, 0.5V or 1.25V
- Operates from 2.7V to 5.5V supply
- General Purpose 256-Byte EEPROM with Write Protect
- I2C 2-wire serial bus for programming configuration and monitoring status
Applications
- In-system test and control of Point-of-Load (POL) Power Supplies for Multi-voltage Processors, DSPs and ASICs
