AP9101CAK6-CETRG1

Battery Management Overview

The AP9101CAK6-CETRG1 is a single-chip protection IC designed for one-cell lithium-ion or lithium-polymer rechargeable battery packs. Manufactured by Diodes Incorporated, it integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, and current abnormalities. The device controls external MOSFET switches to isolate the battery during fault conditions. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output detection voltages from 2.3 V to 4.275 V. The component is housed in an SOT-26-6 surface-mount package and functions reliably across temperatures from -40°C to +85°C.

Battery Management Feature Summary

• Integrates high-accuracy voltage detection for overcharge and overdischarge protection without requiring external timing capacitors due to built-in fixed time circuits.
• Provides comprehensive battery safety by detecting abnormal currents and voltages to automatically turn off external MOSFET switches.
• Supports low-power operation with minimal current consumption in both active and power-down modes.

Battery Management Applications

• Protection circuits for single-cell lithium-ion battery packs
• Safety management for lithium-polymer rechargeable batteries
• Portable electronic devices requiring integrated battery protection
