AP9101CK6-BLTRG1

Battery Management Overview

The AP9101CK6-BLTRG1 is a single-cell battery protection IC from Diodes Incorporated, designed for lithium-ion and lithium-polymer rechargeable batteries. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, activating external MOSFET switches to isolate the battery during faults. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages typically between 2.8 V and 4.28 V. It features low power consumption with a typical operating current of 3.0 µA at 25°C and 3.5 V. The component is housed in an SOT-26-6 surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Battery Management Procurement Notes

Verify the specific suffix BLTRG1 against official Diodes Incorporated documentation to confirm exact detection voltage thresholds and hysteresis values, as these parameters vary significantly across the AP9101C series. Confirm current availability status directly with authorized distributors, as inventory levels fluctuate. Ensure that the ordering information matches the required package type and tape-and-reel quantity specifications for your production line requirements.

Battery Management Selection Notes

Select this component when designing protection circuits for single-cell Li-ion or Li-Po batteries requiring minimal external components. The integrated timing functions reduce bill-of-materials complexity compared to discrete solutions. Ensure the application's maximum operating voltage remains within the 5.5 V limit and that the thermal environment stays within the specified -40°C to +85°C range for reliable operation.
