The TEST pin is an input pin that is used during IC level test. This pin should be connected directly to ground for
normal device operation.
The FAULT pin is an open drain output pin. This pin will be pulled low by the device when an unmasked fault has
been detected. The fault masks are programmed via SPI message #7.
Electrical Characteristics:
V5D = 4.75V to 5.25V, Vbat = 5.5V to 42V,
current flowing into pin (unless otherwise specified)

The TLE7242 2G includes both on-state and off-state diagnostics. On-state diagnostics are active when the OUTx
pin is driven high and off-state diagnostics are active when the OUTx pin is driven low. A detected fault can be
used to activate the open drain FAULT pin on the IC. This pin can be used to interrupt the microcontroller when a
