What is PAC1934T-I/J6CX used for?
The PAC1934T-I/J6CX is ideal for multi-rail power monitoring in servers, embedded computing platforms, and portable electronics where tracking per-channel power consumption across 4 voltage rails is required. It suits battery management systems and cloud computing hardware that need continuous energy accumulation without constant CPU polling. The WLCSP-16 package makes it particularly attractive for space-constrained designs such as wearables and compact IoT gateways.

Frequently Asked Questions
How many power channels can the PAC1934T-I/J6CX monitor simultaneously, and what bus voltage range does it support?
The PAC1934T-I/J6CX monitors 4 independent DC power channels simultaneously, supporting bus voltages from 0 V to 32 V per channel. This allows it to cover a wide range of system rails, from low-voltage digital supplies at 1.8 V to higher analog rails up to 32 V, all within a single 16-pin WLCSP device.
What is the package size of the PAC1934T-I/J6CX and how does it benefit PCB layout in space-constrained designs?
The PAC1934T-I/J6CX uses a WLCSP-16 package measuring approximately 1.62 mm x 1.42 mm with a 0.5 mm pitch bump array, providing one of the smallest footprints available for a 4-channel power monitor IC. This makes it especially suited for wearables, IoT modules, and compact compute modules where board area is limited.
When would the PAC1934T-I/J6CX be preferred over the PAC1921 for a server power management design?
The PAC1934T-I/J6CX is preferred over the single-channel PAC1921 when a design requires monitoring 4 independent power rails simultaneously, such as tracking 3.3 V, 5 V, 12 V, and a variable CPU rail in a server platform. Its internal energy accumulation over 28-week lead times and I2C addressability make it more suitable for multi-channel system telemetry in 1U rack servers.
Does the PAC1934T-I/J6CX support bidirectional current sensing for battery charge and discharge monitoring?
Yes. The PAC1934T-I/J6CX supports bidirectional current sensing on all 4 channels, allowing detection of both charging (positive current) and discharging (negative current) flows. This makes it suitable for battery management systems in laptops and embedded devices where net energy flow across a 0 V to 32 V rail needs to be accurately tracked over time.
