The TPS3847085DBVT: The reset timeout is 4.5 ms typical, long enough to allow the downstream rail to settle before the processor starts code execution.
The push-pull output eliminates the pull-up resistor that open-drain supervisors require, saving one component and one PCB trace per channel.
The TPS3847085DBVT is an active Texas Instruments part.
No. The TL7702BID has an open-drain output and a propagation-delay-based reset (270 ns typical), while the TPS3847085DBVT uses a push-pull output with a 4.5 ms timeout. The pinout and threshold voltage also differ — a board spin is required to swap between them.
