INTRODUCTION

The SMM153 is a highly accurate power supply voltage/current supervisor and monitor that allows realtime power measurement for power-critical designs. The part includes an internal voltage reference to accurately monitor the supply to within ±1. The SMM153 can read the differential voltage of the supply and voltage drop of the current sense resistor over the I2C bus using an onchip 10-bit ADC.
