AP9101CAK6-AMTRG1

Battery Management Overview

The AP9101CAK6-AMTRG1 is a single-cell lithium-ion and lithium-polymer battery protection IC from Diodes Incorporated. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, controlling external MOSFET switches for protection. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages between 2.3 V and 4.275 V. It features low power consumption with typical operating currents of 3 µA and power-down currents of 0.01 µA. 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-accuracy voltage detection for overcharge and overdischarge protection without requiring external timing capacitors due to built-in fixed time circuits.
• Provides comprehensive fault protection against overcurrent and overvoltage conditions by controlling external MOSFET switches.
• Supports ultra-low power operation with minimal current draw in both active and power-down modes to preserve battery life.

Battery Management Applications

• Protection circuits for single-cell lithium-ion rechargeable battery packs
• Safety management for lithium-polymer battery systems in portable electronics
• Battery management units requiring compact surface-mount integration

Battery Management Procurement Notes

Verify the specific suffix AMTRG1 against official Diodes Incorporated documentation to confirm exact detection voltage thresholds and hysteresis settings. Confirm package type and RoHS compliance status directly with the manufacturer or authorized distributors. Check for any product change notices or end-of-life announcements prior to final design approval.

Battery Management Selection Notes
