Frequently Asked Questions
What type of output does the TLV1391CDBVRG4 have?
The TLV1391CDBVRG4 has an open-collector (open-drain) output stage, which requires an external pull-up resistor to the desired logic supply voltage. This configuration allows the output to interface with different logic voltage levels than the comparator supply, enables wired-OR connection of multiple comparator outputs for fault bus architectures, and provides flexibility in output logic level selection.
What is the input offset voltage of the TLV1391CDBVRG4?
The TLV1391CDBVRG4 has a maximum input offset voltage of 5000 µV (5 mV), which sets the minimum voltage difference between the two inputs that the comparator can reliably detect. This offset must be considered when designing precise threshold detection circuits, as it represents a potential error in the comparison voltage point across the full operating temperature range.
What package is the TLV1391CDBVRG4 available in?
The TLV1391CDBVRG4 is housed in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5), a very compact and cost-effective package for single-channel analog ICs. The SOT-23-5 provides the non-inverting input, inverting input, output, and power supply connections in an ultra-small footprint ideal for portable and densely populated PCB designs.
What applications is the TLV1391CDBVRG4 best suited for?
The TLV1391CDBVRG4 is best suited for battery voltage monitoring, supply rail supervision, analog signal threshold detection, and logic-level translation circuits. Its open-collector output makes it particularly useful for generating interrupt signals for microcontrollers, driving indicator LEDs through pull-up resistors, and implementing simple analog-to-digital conversion in low-cost sensor interfaces where single-threshold comparisons are sufficient.
