The TPS3803G15-Q1 device has a fixed-sense threshold voltage VIT set by an internal voltage divider, whereas the TPS3803-01-Q1 has an adjustable SENSE input that can be configured by two external resistors. In addition to the fixed sense threshold monitored at VDD, the TPS3805-Q1 devices provide a second adjustable SENSE input. RESET is asserted in case either of the two voltages drops below VIT. During power on, RESET is asserted when supply voltage VDD becomes higher than 0.8 V. Thereafter, the supervisory circuit monitors VDD (and/or SENSE) and keeps RESE...
