Applications
The PAC1954T-E/J6CX is well suited for server power management systems where monitoring 4 independent power rails in a space-constrained 16-ball WLCSP package is critical. It is also used in industrial IoT gateways and telecom equipment requiring precise current sensing at up to 32 V with SMBus reporting. Battery-powered portable devices benefit from its low-power monitoring capabilities across multiple supply channels.

Frequently Asked Questions
How many power channels can PAC1954T-E/J6CX monitor simultaneously, and what is the maximum input voltage?
The PAC1954T-E/J6CX monitors 4 independent high-side current channels simultaneously with a maximum input voltage of 32 V. Each channel provides independent current and power accumulation, making it suitable for multi-rail server and industrial power management designs.
Which communication interface does PAC1954T-E/J6CX use, and how does it fit into a multi-device power monitoring architecture?
PAC1954T-E/J6CX uses an I2C/SMBus interface operating up to 400 kHz, with configurable device addresses allowing multiple units on the same bus. This makes it straightforward to scale a design to 8 or more monitored rails by daisy-chaining 2 devices with different addresses in a 32 V system.
What package does PAC1954T-E/J6CX use and how compact is the footprint for dense PCB layouts?
PAC1954T-E/J6CX is housed in a 16-ball WLCSP (Wafer-Level Chip Scale Package), which offers an extremely small PCB footprint of approximately 2.03 mm x 1.63 mm. This compact size enables high-density board layouts for portable and space-constrained applications requiring 4-channel power monitoring.
When would a designer choose PAC1954T-E/J6CX over a single-channel power monitor?
A designer chooses PAC1954T-E/J6CX when monitoring 4 rails is needed while minimizing component count and board area. A single IC replaces 4 discrete current sensors, reducing BOM by at least 3 components and saving over 50% PCB space compared to individual monitors, especially valuable in systems with 32 V multi-rail architectures.
