AP9101CK6-BITRG1

Battery Management Overview

The AP9101CK6-BITRG1 is a single-chip protection IC for 1-cell lithium-ion and lithium polymer batteries, manufactured by Diodes Incorporated. It detects overcharge voltage, overdischarge voltage, overcharge current, and overdischarge current to turn off external MOSFET switches. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output detection voltages from 2.3 V to 4.28 V. It features low current consumption of 3 µA in operation mode and utilizes an SOT-26-6 surface-mount package with an operating temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Integrated high-precision voltage detection circuit for monitoring battery status
• Built-in fixed time circuit eliminates the need for external capacitors
• Shutdown input capability for power management control

Battery Management Applications

• Protection circuits for portable electronic devices
• Single-cell lithium-ion battery pack management
• Lithium polymer rechargeable battery safety systems

Battery Management Procurement Notes

Verify the specific suffix BITRG1 against official Diodes Incorporated documentation to confirm exact detection thresholds and hysteresis values. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the SOT-26-6 package compatibility matches your PCB footprint requirements before finalizing procurement orders.

Battery Management Selection Notes

Select this component when designing compact battery protection systems requiring minimal external components. The integrated timing circuit reduces bill of materials complexity compared to solutions requiring external RC networks. Ensure the selected detection voltage ranges align with the specific chemistry and capacity of the target lithium-ion or lithium-polymer cell being protected.

Battery Management Part Context

This part belongs to the AP9101C series of battery management ICs designed for single-cell applications. It serves as a specialized PMIC solution focusing on safety rather than active charging regulation. The SOT-26 package allows for space-constrained designs common in modern mobile and wearable electronics.

Battery Management Replacement Considerations

Check for AP9101CK6 variants with different suffixes (e.g., BSTRG1, BUTRG1) which may offer adjusted voltage detection parameters. Verify pinout compatibility if substituting with other single-cell protection ICs from alternative manufacturers.
