Description

HY2120 ICs is best created for 2-cell lithium-ion/lithium polymer rechargeable battery protection and it also comprises high-accuracy voltage detectors and delay circuits. These ICs are suitable for protecting 2-cell rechargeable lithium-ion/lithium polymer battery packs against the problems of overcharge, overdischarge and overcurrent.

Technical parameters:

The features that whole series of HY2120 comprised are as follows:

(1) High-accuracy voltage detection circuit

● Overcharge detection voltage VCUn  (n=1, 2)   4.10 to 4.50V     Accuracy  ±25mV

● Overcharge release voltage VCRn    (n=1, 2)   3.90 to 4.30V     Accuracy  ±50mV

● Overdischarge detection voltage VDLn (n=1, 2)  2.00 to 3.20V      Accuracy  ±80mV

● Overdischarge release voltage VDRn  (n=1, 2)  2.30 to 3.40V     Accuracy  ±100mV

● Discharge overcurrent detection voltage      (by option)       

● Charge overcurrent detection voltage        (by option)           Accuracy  ±30mV

● Short-circuiting detection voltage            1.0V(fixed)           Accuracy  ±0.4V (2)Delay times are generated by an internal circuit (external capacitors are unnecessary).

● Overcharge delay time       1000ms typ.

● Overdischarge delay time      110ms typ.

● Discharge overcurrent delay time     10ms typ.

● Charge overcurrent detection voltage    7ms typ.

● Short circuit delay time       250μs typ. (3) Low current consumption(Products with Power-down Function)

● Operation mode                 5.0μA typ., 9.0μA max. (VDD=7.8V)

● Ultra low power-down current at   0.1μA max. (VDD=4.0V)

(4) High-withstanding-voltage device is used for charger connection pins (CS pin and OC pin : Absolute maximum rating = 33 V)

(5) 0 V battery charge function “available” / “unavailable” are selectable

(6) Wide operating temperature range −40°C to +85 °C

(7) Small package SOT-23-6 

(8) The HY2120 series are Halogen-free, green package
