U2403B-M

Overview

The U2403B-M is a battery charger timer integrated circuit manufactured by Microchip Technology, housed in an 8-DIP package. It supports a maximum supply voltage of 13.7V and operates within a junction temperature range of -10°C to 150°C. The device provides constant current charging capabilities and includes overtemperature fault protection. This component is currently listed as obsolete.

Feature Summary

Provides constant current charging control for battery management applications
Integrates overtemperature fault protection for enhanced safety
Designed for through-hole mounting via 8-pin DIP configuration

Applications

Battery charging systems requiring timer functionality
Portable electronic devices with NiCd or NiMH batteries
Industrial equipment battery maintenance circuits

Procurement Notes

Verify component obsolescence status before integration into new designs. Confirm package compatibility with existing PCB footprints. Review datasheet specifications for thermal performance limits. Ensure supply chain availability for legacy production runs. Validate electrical parameters against system requirements.

Selection Notes

Consider the 8-DIP package constraint for board layout. Evaluate the 13.7V maximum supply voltage limit. Assess the operating temperature range for environmental conditions. Check if constant current charging meets specific battery chemistry needs. Verify overtemperature protection thresholds.

Part Context

This part belongs to Microchip's battery charger timer series. It serves as a dedicated solution for managing charge cycles without complex microcontroller intervention. The 8-DIP variant offers through-hole assembly options compared to surface-mount alternatives.
