... I is the desired current limit. LIMIT Short-Circuit Protection The MAX893L is a short-circuit protected switch. In the event of an output short circuit or a current overload condition, the current through the switch is limited by the internal current-limiting error amplifier to 1.5 · I The short-circuit current is typically 1.8A for a pro- grammed current limit of 1 ...

... If the fault condition is not removed, the switch will cycle on and off, resulting in a pulsed out- put. The MAX893L provides a fault output (FAULT). This open-drain output goes low when in current limit or when the die temperature exceeds +165°C. A 100kΩ ...
