MAX6848KATD3

Overview

The MAX6848KATD3 is a low-power, adjustable battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates within a supply voltage range of 1.6 V to 5.5 V and is housed in an SOT-23-8 package. The device supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides user-adjustable low-battery output thresholds with hysteresis for precise power management signaling.
• Integrates an independent microprocessor supervisor that monitors the supply voltage and provides an active-low reset output.
• Includes a manual reset function accessible via a pushbutton to force a system reset.

Applications

• Single-cell lithium-ion battery monitoring systems
• Multicell alkaline or NiCd/NiMH battery pack supervision
• Microprocessor reset circuitry in portable electronic devices

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and pin alignment against the SOT-23-8 specification before integration. Review official discontinuation notifications for lifecycle implications and long-term supply constraints.

Selection Notes

Select this component when adjustable battery thresholds are required alongside dedicated CPU reset functionality. Ensure the input voltage range aligns with the target battery chemistry. Verify that the SOT-23-8 footprint matches the PCB layout requirements for the specific application design.

Part Context

This part belongs to the MAX6846–MAX6849 family of ultra-low-power battery monitors. These devices are designed to eliminate external components by integrating both battery monitoring and microprocessor supervision into a single compact solution suitable for space-constrained portable applications.
