The HY2113-RB1A is Hongkang's high-precision single-cell lithium battery protection IC.

The HY2113-RB1A is a protection IC for single-cell rechargeable lithium batteries. The following details its features, applications, and a comparison with similar models:

Feature

• High-Precision Voltage DetectionThe high-precision voltage detection circuit features overcharge detection voltage ranging from 4.000 to 4.500V with an accuracy of ±25mV; overcharge release voltage from 3.800 to 4.500V with an accuracy of ±50mV; over-discharge detection voltage from 2.00 to 3.10V with an accuracy of ±50mV; and over-discharge release voltage from 2.00 to 3.40V with an accuracy of ±50mV.

• Overcurrent DetectionThe discharge overcurrent detection voltage ranges from 25 to 250mV with an accuracy of ±15mV. Additionally, the charging overcurrent detection voltage is available. For load short-circuit detection, the voltage is fixed at 0.85V, with an accuracy of ±0.3V.

• Additional featuresSelectable with over-discharge recovery and sleep functions, models with sleep function feature low quiescent current, with typical values of 3.0μA and maximum of 6.0μA (VDD=3.9V), and sleep mode maximum of 0.1μA (VDD=2.0V). The terminals for connecting the charger are designed for high voltage resistance, with CS and OC terminals rated at 20V. Options also include whether to allow charging to a 0V battery, with operating temperature range of -40℃ to +85℃，and comes in a compact DFN-1.8*2.0-6L or SOT-23-6 package. It is a halogen-free green environmental product.

Applied

Primarily applied to 1 lithium-ion rechargeable battery pack and 1 lithium polymer rechargeable battery pack, such as single-cell lithium-ion battery protection integrated into small portable electronic devices, including electric toothbrushes, smart magnetic door sensors, and small mobile power banks.

Similar Model Comparison

• HY2113-OB1CThe HY2113-RB1A is functionally similar, being a single-cell lithium-ion/lithium polymer battery protection IC with the same SOT-23-6 package. It features high-precision voltage detection and overcurrent detection, and also offers options for over-discharge self-recovery and sleep modes. Both can be interchanged in many applications.
