AP9101CAK-BVTRG1

Overview

The AP9101CAK-BVTRG1 is a single-chip protection IC designed for lithium-ion and lithium-polymer rechargeable battery packs. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, automatically turning off external MOSFET switches during abnormalities. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.4 V to 4.5 V. It features low power consumption with typical operating current of 3.0 µA at +25°C and 0.01 µA in power-down mode. Packaged in SOT-25-5, it functions reliably between -40°C and +85°C.

Feature Summary

• Integrates high-precision voltage detection for overcharge and overdischarge protection without requiring external timing capacitors.
• Provides comprehensive fault protection against overcurrent and abnormal voltage states by controlling external MOSFETs.
• Features ultra-low current consumption in both active operation and power-down modes to preserve battery life.

Applications
