Texas Instruments TLV192x 65V Open-Drain Comparators
Texas Instruments TLV192x 65V Open-Drain Comparators are a family of 65V comparators with an integrated 2.5V reference that is externally accessible. The inputs are fail-safe tolerant up to 65V, independent of the supply voltage. This feature makes the comparators well-suited for 12V and 24V industrial systems where operating voltage compliance to 65V is required. Likewise, the fail-safe inputs eliminate power supply sequencing concerns.
The single and dual channel options have an externally available 2.5V reference output and undedicated comparator inputs, allowing for inverting and non-inverting configurations. The dual also has an externally available 2.5V reference output, internally connected to the non-inverting input of the first comparator. The dual configuration enables window comparator applications or dual channel over-voltage detection.
The Texas Instruments TLV192x includes a Power-On Reset (POR) feature that sets the output to a known state until the minimum supply voltage has been reached and the output responds to the inputs, thus preventing false outputs during system power-up and power-down.
