PAC1944T-E/4MX 产品详情

Description
The PAC194X products are one, two, three and
four-channel energy monitors, with bus voltage
monitors and current sense amplifiers that feed
high-resolution ADCs. There are two versions of the
PAC194X: the PAC194X-1 devices are for high-side
current sensing and the PAC194X-2 devices are for
low-side current sensing or floating VBUS applications.
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 proportional
power are stored in registers for retrieval by
the system host or embedded controller. The PAC194X
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.
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 PAC194X
device family uses real-time calibration to minimize the
offset error. No input filters are required for this device.
