PRODUCT BRIEF Consumer Industrial Intersil Industrial and Consumer Solutions Intersil’s Digital Power Monitoring Solutions Intersil’s Digital Power Monitoring (DPM) devices provide a bi-directional high-side and low-side digital current sense and voltage monitor with serial interface. The device monitors current and voltage and provides the results digitally along with calculated power. The DPM provides tight accuracy with 16-bit ADC for both voltage and current monitoring over the entire input range. The DPM handles common-mode input voltage ranging from 0V to 60V. The wide range permits the device to handle telecom, automotive and industrial applications with minimal external circuitry. Both high and low-side ground sensing applications are easily handled with the flexible architecture.
