AP9101CK6-CFTRG1

Battery Management Overview

The AP9101CK6-CFTRG1 is a single-chip protection IC designed for lithium-ion and lithium-polymer rechargeable battery packs. Manufactured by Diodes Incorporated, it integrates high-precision voltage detection circuits to safeguard against overcharge, overdischarge, overcharge current, and overdischarge current conditions by controlling external MOSFET switches. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.8 V to 4.28 V. It features low power consumption with a typical operating current of 3 µA at +25°C and 3.5 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-precision voltage detection for comprehensive battery protection including overcharge, overdischarge, and current abnormalities.
• Eliminates the need for external timing capacitors through built-in fixed time circuits, reducing external component count.
• Operates with ultra-low current consumption in both active and power-down modes to preserve battery life.
• Supports standard SOT-26 packaging for compact surface-mount assembly.

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 monitoring

Battery Management Procurement Notes

Verify the specific suffix CFTRG1 against official Diodes Incorporated documentation to confirm exact detection voltage thresholds and hysteresis settings. Ensure compatibility with target PCB footprint and thermal requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

Battery Management Selection Notes

Select this component when designing protection circuits for single-cell Li-ion or Li-Po batteries requiring minimal external components. Consider the SOT-26 package size constraints and the required detection accuracy levels. Evaluate the operating temperature range against the intended application environment. Verify that the external MOSFET selection aligns with the IC's drive capabilities and the battery's maximum current specifications.

Battery Management Part Context

This part belongs to the AP9101C series of battery management ICs from Diodes Incorporated. The series focuses on providing complete protection solutions for rechargeable batteries with high precision and low power consumption. Variants within the series typically differ by detection voltage parameters and package options, such as SOT-25 or SOT-26, allowing designers to tailor protection characteristics to specific battery chemistries and safety standards.

Battery Management Replacement Considerations

Check for direct substitutes within the AP9101C family or other single-cell battery protection ICs from Diodes Incorporated. Ensure any replacement matches the SOT-26-6 package, voltage ranges, and protection thresholds. Verify pinout compatibility if swapping between different manufacturers' equivalents to avoid circuit redesign.
