How to measure the maximum current for charge overcurrent detection of HY2111 series?
The maximum current for charge overcurrent is calculated by ＩCIP＝︱VCIP︱/ RON﹒ (3)
Where ICIP is the maximum current for charge overcurrent, VCIP is the charge overcurrent detection voltage. RON is the sum of internal resistance of M1 and M2 MOSFET.
HY2111-EB for example, VCIP is -0.1V (typ.) and RON is 50mΩ. Then, ICIP is 2A.
