Current-Limit Switches Detailed Description The MAX4795–MAX4798 are forward/reverse current- limited switches that operate from 4.5V input voltage range and guarantee a 450mA and 500mA minimum current-limit threshold for different options. The voltage drop across an internal ...

Current-Limit Switches Autoretry (MAX4796/MAX4798) When the forward or reverse current-limit threshold is exceeded, t timer begins counting (Figure 2). BLANK The timer resets if the overcurrent condition disappears before t has elapsed. A retry time delay, t BLANK is ...
