AP9101CK-BJTRG1

Battery Management Overview

The AP9101CK-BJTRG1 is a battery management integrated circuit manufactured by Diodes Incorporated, designed for single-cell lithium-ion and lithium-polymer rechargeable batteries. It functions as a multicell battery manager with charge management capabilities. 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 4.4 V. It is housed in an SOT-25-5 surface-mount package and complies with RoHS standards. The component operates reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Provides protection against overcharge, overdischarge, overcharge current, and overdischarge current abnormalities by controlling external MOSFET switches.
• Features high-precision voltage detection circuits with fixed time functionality that eliminates the need for external capacitors.
• Maintains low power consumption with typical operation current of 3.0µA and power-down mode current of 0.01µA.

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

Battery Management Procurement Notes

Verify the specific suffix BJTRG1 against official Diodes Incorporated documentation to confirm exact detection voltage thresholds and hysteresis values, as these parameters vary significantly across the AP9101C series. Confirm availability status directly with the manufacturer or authorized distributors, as inventory levels fluctuate. Ensure the ordering information matches the required package type and environmental compliance specifications before finalizing procurement.

Battery Management Selection Notes

Select this component when designing protection circuits for single-cell Li-ion or Li-Po batteries requiring minimal external components due to its built-in fixed time delay. Consider the SOT-25-5 package constraints for space-limited applications. Evaluate the specific voltage detection thresholds associated with the BJ suffix to ensure they align with the target battery's maximum and minimum operating limits.

Battery Management Part Context

The AP9101CK-BJTRG1 belongs to the AP9101C family of battery protection ICs from Diodes Incorporated. This series is engineered to provide comprehensive safety monitoring for portable electronics by integrating high-accuracy detection and control logic into a small footprint. The family supports various voltage configurations through different suffixes, allowing designers to tailor protection levels to specific cell chemistries.

Battery Management Replacement Considerations

Cross-reference other AP9101C variants with matching detection voltages and the same SOT-25-5 package. Verify functional compatibility regarding protection thresholds and interface requirements before substitution.
