How to measure the maximum current for abnormal charge current detection of HY2110 series?
The maximum current for abnormal charge current is calculated by ＩCHA＝︱VCHA︱/ RON﹒ (2)
Where ICHA is the maximum current for abnormal charge current, VCHA is the charger detection voltage. RON is the sum of internal resistance of M1 and M2 MOSFET.
HY2110-AB for instance, VCHA is -0.3V (typ.), and RON is 50mΩ. Then, ICIP is 6A.
