PAC1942T-2E/4MX

Current Regulation/Management Overview

The PAC1942T-2E/4MX is a two-channel power monitor manufactured by Microchip Technology, designed for high-side sensing applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an operating supply current of 395 uA. The device provides measurement accuracy of 1% and functions across a temperature range from -40°C to +125°C. It is housed in a VQFN-16 surface-mount package.

Current Regulation/Management Feature Summary

• Supports high-side current and power monitoring with integrated accumulator functionality
• Delivers precise measurements with 1% accuracy across wide operating conditions
• Optimized for low-power systems with minimal operating supply current consumption

Current Regulation/Management Applications

• Battery management systems requiring high-side current monitoring
• Portable electronic devices with strict power budget constraints
• Industrial equipment needing reliable power regulation verification

Current Regulation/Management Procurement Notes

Verify the specific suffix '4MX' against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with the required VQFN-16 footprint and thermal performance specifications before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required for dual-channel power monitoring. The VQFN-16 package suits space-constrained designs. Confirm that the 1% accuracy meets system requirements and that the 395 uA quiescent current aligns with battery life expectations.

Current Regulation/Management Part Context

This part belongs to the PAC194x series of multi-channel power monitors from Microchip Technology. These devices are engineered for accurate energy metering and power regulation monitoring in compact form factors, supporting both high-side and low-side configurations depending on the specific model variant.

Current Regulation/Management Replacement Considerations

Consult official substitution lists for equivalent Microchip power monitors. Verify pinout compatibility and functional equivalence with other PAC194x variants or similar high-side sensing ICs before implementation.
