Overview
The AP9101CAK-AXTRG1 is a single-chip protection IC designed for one-cell lithium-ion or lithium-polymer rechargeable battery packs. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, and current abnormalities, controlling external MOSFET switches for safety. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.4 V to 4.5 V. It features low current consumption of 3 µA in operation mode and 0.01 µA in power-down mode. The component is housed in an SOT-25-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-accuracy voltage detection for overcharge and overdischarge protection with built-in fixed time circuits requiring no external capacitors.
- Provides comprehensive fault protection against overcurrent and overvoltage conditions by controlling external MOSFET switches.
- Designed for minimal external component count, offering a compact solution for single-cell battery management systems.
Applications
- Protection circuits for single-cell lithium-ion battery packs
- Safety monitoring for lithium-polymer rechargeable batteries
- Portable electronic devices requiring integrated battery management
Procurement Notes
Verify the specific suffix AXTRG1 against official Diodes Incorporated documentation to confirm exact electrical tolerances and packaging details. Ensure compatibility with the target PCB footprint, specifically the SOT-25-5 package dimensions. Confirm that the required detection voltage steps align with the system's battery specifications before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact, single-cell battery protection solution with low quiescent current. The SOT-25-5 package suits space-constrained designs. Verify that the external MOSFETs selected can handle the expected load currents and that the system voltage remains within the 1.5 V to 5.5 V operating range for reliable detection functionality.
