AP9101CK6-CQTRG1

Battery Management Overview

The AP9101CK6-CQTRG1 is a battery management IC from Diodes Incorporated, designed for single-cell lithium-ion and lithium-polymer rechargeable batteries. It provides comprehensive protection by detecting overcharge voltage, overdischarge voltage, overcharge current, and overdischarge current abnormalities, subsequently turning off an external MOSFET switch. The device features a high-precision voltage detection circuit with built-in fixed time circuits, eliminating the need for external capacitors. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.5 V to 4.275 V. The component is housed in an SOT-26-6 package, suitable for surface mount installation, and functions reliably across temperatures from -40°C to +85°C.

Battery Management Feature Summary

• Provides multi-fault protection including overcharge, overdischarge, overcharge current, and overdischarge current detection for single-cell Li-ion and Li-polymer batteries.
• Integrates a high-precision voltage detection circuit with built-in fixed time delays, reducing the requirement for external components.
• Operates with ultra-low power consumption, featuring a typical operating current of 3 µA and a power-down mode current of 0.01 µA.

Battery Management Applications

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

Battery Management Procurement Notes

Verify the specific suffix 'CQ' against the official Diodes Incorporated datasheet to confirm the exact overcharge detection voltage and hysteresis settings, as these parameters vary across the AP9101C series. Confirm availability status directly with authorized distributors, as some variants may be subject to discontinuation notices or limited stock conditions. Ensure the ordering part number matches the required package type and temperature range specifications for your application.

Battery Management Selection Notes

Select this component when designing protection circuits for single-cell lithium-based batteries that require minimal external component count due to its integrated timing functions. Consider the SOT-26-6 package size constraints and the specific voltage detection thresholds defined by the 'CQ' suffix. Evaluate the low standby current requirements if battery longevity in power-down modes is critical for the end product.

Battery Management Part Context

The AP9101CK6-CQTRG1 belongs to the AP9101C series of battery management ICs manufactured by Diodes Incorporated. This series is specifically engineered as a single-chip solution for protecting lithium-ion and lithium-polymer battery cells. The 'CK6' designation typically indicates the SOT-26-6 package variant, while the suffix determines specific electrical characteristics such as detection voltages.
