Summary of PAC1710 CURRENT SENSING MONITOR IC
Microchip’s PAC1710 is a high-side bidirectional current sensing monitor IC that measures voltage across an external sense resistor and the SENSE+ pin to derive current and average power. It offers long integration (2.5 ms–2.6 s) with up to 11-bit resolution, 1% positive-range accuracy, bidirectional sensing, auto-zero offset, digital averaging, adjustable sampling/resolution, and programmable alerts via ALERT#. It supports VSOURCE 0–40 V, has 5 µA standby, and comes in a RoHS-compliant 3 mm x 3 mm DFN-10 package for use in notebooks, desktops, industrial and embedded power-management applications.

Microchip’s high-side bidirectional current sensing monitor ICs come in a RoHS compliant DFN package
The PAC1710 from Microchip Technology is a high-side bidirectional current sensing monitor with precision voltage measurement capabilities. The power monitor measures the voltage developed across an external sense resistor to represent the high-side current of a battery or voltage regulator.
The PAC1710 also measures the SENSE+ pin voltage and calculates average power over the integration period. The PAC1710 can be programmed to assert the ALERT# pin when high and low limits are exceeded for current sense and bus voltage. It is available in a RoHS compliant 3 mm x 3 mm 10-pin DFN package.
The PAC1710 device is good for measuring dynamic power. The long integration time allows for extending system polling cycles without losing any power consumption information. In addition, the alert ensures that transient events are captured between the polling cycles. These current sensing products are ideal for notebooks, desktop computers, industrial, power management systems, and other embedded applications.
