Description as follow:

The TPS3803-01DCKR is a voltage detector. The TPS3803-01DCKR supervisory circuit provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. The TPS3803-01DCKR device has a fixed-sense threshold voltage VIT set by an internal voltage divider, whereas the TPS3803.01 has an adjustable SENSE input that can be configured by two external resistors.
