PAC1944T-E/J6CX

Current Regulation/Management Overview

The PAC1944T-E/J6CX is a four-channel DC power monitor with an accumulator, manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports high-side sensing. The device features ±1% accuracy for current and power measurements. It functions across an extended temperature range from -40°C to +125°C. The component is housed in a 16-pin WLCSP package and is designed for surface mount installation.

Current Regulation/Management Feature Summary

• Four-channel simultaneous monitoring capability
• Integrated accumulator function for energy tracking
• High-side current sensing architecture
• Extended industrial temperature operation

Current Regulation/Management Applications

• Battery management systems
• Portable electronic devices
• Industrial equipment power monitoring
• Automotive electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the required packaging format. Confirm the E-grade designation matches the intended operating temperature range requirements. Ensure compatibility with the target PCB footprint for the 16-pin WLCSP package before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when four independent channels are required for power monitoring. The high-side sensing feature simplifies circuit design compared to low-side alternatives. The wide operating temperature range makes it suitable for harsh environments. Verify that the supply voltage constraints align with the system's power rails.

Current Regulation/Management Part Context

This part belongs to the PAC194X series of power monitors. It shares functional similarities with other members like the PAC1942 but offers four channels instead of two. The series is characterized by high accuracy and low power consumption. It is distinct from the PAC1934 which has different channel counts and temperature ratings.

Current Regulation/Management Replacement Considerations

The PAC1942T-1E/J6CX is a related two-channel variant. Verify channel count requirements before substitution. Other PAC194X family members may offer similar functionality with different pinouts or features.
