Output Logic Configurations

TPS38 has two channels with separate sense pins and reset pins that can be configured independently of each other. Channel 1 is available as Open-Drain and Push-Pull while channel 2 is only available as Open-Drain topology.

The available output logic configuration combinations are shown in Table Table 8-2.
