PAC1710/20 Single and Dual High-Side Current-Sense Monitor with Power Calculation Features Description Single and Dual High-Side Current Sensor The PAC1710/20 are single and dual high-side bidirectional current sensing monitors with precision - Current measurement is integrated over 2.5 ms voltage measurement capabilities. Each sensor to 2.6 seconds with up to 11-bit resolution measures the voltage developed across an external - 1% current measurement accuracy in sense resistor to represent the high-side current of a positive range battery or voltage regulator. The PAC1710/20 also - Measures V voltages SOURCE measures the SENSE+ pin voltage and calculates Calculates Power average power over the integration period. The V Voltage Range 0V to 40V PAC1710/20 can be programmed to assert the ALERT SOURCE pin when high and low limits are exceeded for Current Bidirectional Current Sensing Sense and Bus Voltage. Auto-Zero Input Offset Voltage Digital Averaging The PAC1710/20 device is good for measuring dynamic power. The long integration time allows for - Adjustable sampling time and resolution extending system polling cycles without losing any 5 A Typical Standby Current power consumption information. In addition the alert Programmable Sense Voltage Range ensures that transient events are captured between the - 10 mV, 20 mV, 40 mV, and 80 mV polling cycles. Power Supply Range 3.0V to 5.5V Available in a RoHS compliant 3 x 3 mm 10-pin VDFN Wide Temperature Operating Range: -40C to package. +85C ALERT Output for Voltage and Current out of Package Types Limit Transients Between Sampling Interval PAC1710/20 SMBus 2.0 Communications Interface 3x3 VDFN* - Block Read and Block Write - Address selectable by resistor decode SENSE1+ V 1 10 DD Sample Time Configurable from 2.5 ms to 320 ms SENSE1- SMCLK 2 9 - With averaging effective sampling times up to EP SENSE2+ 3 8 SMDATA 2.6 seconds 11 SENSE2- ALERT 4 7 10-Lead 3 x 3 mm VDFN package GND 5 6 ADDR SEL Applications *Includes Exposed Thermal Pad (EP), see Table 3-1 Notebook and Desktop Computers Industrial PAC1720 only.
