WSON (DSG)-8-4 mm² 2 x 2

The TLV1921 and TLV1922 are a family of single and dual 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 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 refernce output which is internally connected to the non-inverting input of the first comparator. The dual configuration enables window comparator applications or dual channel over-voltage detection.

All devices include 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.

The Family of comparators have an open-drain output stage that is 65V compliant.
