MC3761PK1HAU

Overview

The MC3761PK1HAU is a single-cell lithium-ion battery protection integrated circuit manufactured by Mitsumi Electric. It integrates high-side and low-side N-channel MOSFETs to provide comprehensive protection against overcharge, overdischarge, and overcurrent conditions. The device operates within a supply voltage range of 2.0V to 5.5V and supports continuous load currents up to 4.0A for discharge and 2.0A for charge. It features a compact 6-pin XFDFN package with an exposed pad for efficient thermal dissipation.

Feature Summary

• Integrates dual N-channel MOSFETs for space-efficient design
• Provides precise overcharge and overdischarge voltage protection
• Includes short-circuit detection with rapid shutdown capability
• Features low on-resistance for minimal power loss

Applications

• Portable electronic devices such as smartphones and tablets
• Power tool battery packs
• Consumer electronics with single-cell lithium-ion batteries
• Medical equipment requiring reliable battery management

Procurement Notes

Verify the exact suffix PK1HAU to confirm the specific tape and reel packaging configuration. Ensure compatibility with your PCB footprint for the 6-XFDFN exposed pad package. Confirm that the manufacturer's standard lead time aligns with your production schedule before placing orders.

Selection Notes

Select this component when a compact solution for single-cell lithium-ion protection is required. The integrated MOSFETs reduce external component count compared to discrete solutions. Ensure the application current does not exceed the 4.0A discharge or 2.0A charge limits specified in the datasheet.

Part Context

This part belongs to the MC3761 series of battery protection ICs from Mitsumi Electric. The series is designed for consumer electronics applications where size and cost are critical factors.
