6.3.3 Standalone Operation

In a typical application, the TPS1H000-Q1 device is controlled by a microcontroller. The device also supports standalone operation. IN and DIAG_EN have a 40V maximum dc rating, and can connect to the VS pin directly. In auto-retry mode, the DELAY pin can also connect to the VS pin through a 100kΩ resistor.
