Overvoltage Protector with  
Active Current Limit  
7–MAX4981  
General Description  
Features  
♦ Input Voltage Protection Up to +28V  
♦ Integrated nFET Switch, 85mΩ (typ)  
The MAX4978–MAX4981 overvoltage-protection devices  
protect low-voltage systems against voltage faults up to  
+28V and feature a low 85mΩ R  
FET, an active cur-  
ON  
♦ Preset Overvoltage Protection Trip Level  
5.7V (typ) (MAX4978/MAX4980/MAX4981)  
6.8V (typ) (MAX4979)  
♦ Low-Current Undervoltage Lockout Mode  
♦ Overcurrent Protection  
rent limiter, and lithium-ion battery overcharge protec-  
tion (MAX4980/MAX4981). These devices are used to  
protect the charger input port on a portable device.  
The overvoltage protector feature protects against volt-  
ages up to 28V with two different trip thresholds: 5.7V  
(MAX4978/MAX4980/MAX4981) and 6.8V (MAX4979).  
There is an undervoltage protector with two different trip  
thresholds: 4.4V (MAX4978) and 2.63V (MAX4979/  
MAX4980/MAX4981).  
♦ Internal 160ms (typ) Startup Delay  
♦ Thermal-Shutdown Protection  
♦ Battery Overcharge Protection  
(MAX4980/MAX4981)  
♦ Startup Debounce Time Indicator  
The overcurrent limiter and battery voltage monitor fea-  
tures provide a second layer of protection for a lithium-  
ion battery charger. The overcurrent limiter is available  
in two different thresholds: 0.9A (MAX4978/MAX4979/  
MAX4980) and 1.95A (MAX4981). Once current reach-  
es the threshold, it is held for a 20ms blanking time. If  
the current is still at the limit after the blanking time, the  
FET is turned off, and the device restarts the cycle after  
160ms. The battery voltage monitor measures the volt-  
age of a lithium-ion battery and disables the FET if the  
battery voltage reaches 4.4V (MAX4980/MAX4981).
