Description

• On-Chip Accumulation of 30-bit Power Results for

Energy Measurement

The PAC195X products are one, two, three and

four-channel energy monitors, with bus voltage moni-

tors and current sense amplifiers that feed

high-resolution ADCs. There are two versions of the

PAC195X: the PAC195X-1 devices are for high-side

current sensing and the PAC195X-2 devices are for

low-side current sensing or floating VBUS applications.

- User programmable sampling rates of 8, 64,

256 and 1024 SPS

- 5120 SPS for a single channel in Burst mode

• 2.7V to 5.5V Supply Operation

- 1.62-5.5V capable I²C/SMBus and digital I/O

- SMBus 3.1 and I²C Fast Mode Plus, 1 Mbps

- High-Speed mode (3.4 Mbps)

Digital circuitry performs power calculations and

energy accumulation. This enables energy monitoring

with integration periods up to one year or longer. Bus

voltage, sense resistor voltage and accumulated pro-

portional power are stored in registers for retrieval by

the system host or embedded controller. The PAC195X

devices have a set of digital comparators that allow the

user to detect over/undervoltage, over/undercurrent

and overpower against user programmed limits for

each channel and generate an ALERT when the

threshold is exceeded.

• SMBus Address – 16 Options, Set with Resistor

• ALERT Features that Can Be Enabled:

- ALERT on conversion complete

- ALERT on Over/Undervoltage and Current or

Overpower conditions

• Coulomb Counting: When Selected, the

Accumulator Accumulates V_SENSEValues.

• 8X Averaging Mode for Single-Shot

Measurements to Reduce Noise and Offset

The sampling rate and energy integration period can be

controlled over SMBus or I²C. Active channel selection,

single-shot measurements and other controls are also

configurable by the SMBus or I²C. The PAC195X

device family uses real-time calibration to minimize the

offset error. No input filters are required for this device.

• Two Independent ALERT/GPIO pins

• AEC-Q100 Qualified (VQFN)

• Available Packages:

- 3 x 3 mm 16-Lead VQFN with wettable flanks

- 2.225 x 2.17 mm 16-Lead WLCSP
