Texas Instruments TLV1805/TLV1805-Q1 High Voltage Comparator
Texas Instruments TLV1805/TLV1805-Q1 High Voltage Comparator offers a unique combination of wide supply range, push-pull output, rail-to-rail inputs, low quiescent current, shutdown capability, and fast output response. All these features make this comparator well-suited for applications that require sensing at the positive or negative voltage rails. These applications include reverse current protection for a smart diode controller, overcurrent sensing, and overvoltage protection circuits where the push-pull output stage is used to drive the gate of a p-channel or n-channel MOSFET switch. The Texas Instruments TLV1805-Q1 devices are AEC-Q100 qualified for automotive applications.
