Overview
The AP4310AMTR-AE1 is a discontinued monolithic integrated circuit from Diodes Incorporated, designed for regulating output current and voltage in switching battery chargers and power supplies. It integrates two operational amplifiers and a 2.5V precision shunt voltage reference within an SO-8 package. The device features a unity gain bandwidth of 1 MHz, an input offset voltage of 0.5 mV, and a supply current of 75 µA per op amp at 5.0 V. The voltage reference offers a tolerance of ±0.4% with a sink current capability ranging from 0.05 to 80 mA.
Feature Summary
- Integrates two operational amplifiers and a 2.5V precision shunt voltage reference on a single chip
- Provides high-precision control solutions for switching power converters
- Features low supply current consumption and wide operating temperature range
Applications
- Battery Charger
- Switching Power Supply
Procurement Notes
Verify component status as the AP4310AMTR-AE1 is officially listed as End-of-Life (EOL) by Diodes Incorporated. Confirm availability through authorized distributors or secondary market suppliers. Ensure compliance with RoHS and lead-free requirements if sourcing replacement inventory. Review datasheet revision DS36510 Rev. 2-2 for accurate electrical specifications before integration into new designs.
Selection Notes
Select this component for applications requiring precise voltage and current regulation in compact designs. The internal connection of Op Amp 1 to the voltage reference simplifies constant voltage control loops. Op Amp 2 remains uncommitted, offering flexibility for current sensing configurations. Consider the SO-8 surface mount package for PCB space optimization. Evaluate system complexity reduction benefits against the availability constraints of this discontinued part number.
Part Context
The AP4310 series belongs to Diodes Incorporated's portfolio of power management ICs tailored for charger and power supply applications. This specific model combines dual op amps with a fixed voltage reference to streamline control circuitry. The 'AE1' suffix indicates a specific packaging or qualification variant within the broader AP4310 family, which also includes active parts like the AP4310AMTR-G1.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate alternative dual op amp and voltage reference combinations or consult Diodes Incorporated for updated product recommendations compatible with existing board layouts.
