HY2112-BB Battery Protection IC HYCON SOT-23-6 C161942

Product Overview

The HY2112 is a protection integrated circuit designed for 1-cell Lithium Iron Phosphate (LiFePO4) rechargeable battery packs. It integrates a high-precision voltage detection circuit and delay circuit to monitor and safeguard battery cells from overcharge, over-discharge, and overcurrent conditions.

Core Specifications

• Manufacturer: HYCON Technology

• Package Type: SOT-23-6

• Function: 1-Cell LiFePO4 battery protection IC

• Operating Voltage: Wide range of supply voltages supported for LiFePO4 chemistry

• Control Interface: Internal logic (integrated delay timers eliminate the need for external capacitors)

Key Features

• High-Precision Voltage Detection: Monitors cells for:

  • Overcharge detection and release.

  • Over-discharge detection and release.

  • Discharge overcurrent, charge overcurrent, and load short-circuit detection.

• Internal Delay Timers: All detection delay times are set internally within the chip, simplifying the external circuit design.

• Low Power Consumption: Designed to draw minimal current during normal operation, preserving battery life in standby modes.

• Robust Protection: Includes integrated circuitry to handle fault conditions and protect the battery from damage.

Operating Characteristics

• Normal Status: The IC monitors the cell voltage and current through the external sense resistor.

• Fault Protection: If voltages or currents exceed predefined safety thresholds for a duration exceeding the internal delay, the IC switches to a protection mode, typically by disabling external MOSFETs.

• Recovery: The device is designed to recover to normal status automatically once the fault condition is removed (e.g., disconnecting a charger or load).

Applications

• LiFePO4 Battery Packs: Specifically optimized for single-cell LiFePO4 battery management systems.

• Portable Electronics: Ideal for small electronic devices, power tools, or communication equipment requiring high-safety LiFePO4 power sources.
