INH-Pin

The INH-pin ("inhibit-pin") is a high-voltage-output controlled by the EN-input. In the normal-mode and in the wait-

The INH-pin may be used to switch on an external regulator or to set external switches active for an interrupt

request. The inhibit-driver is capable to source 40mA typically.

tristating the INH-pin. Hence, a voltage regulator with its inhibit pin connected to INH will be disabled. If the master

node pull-up resistor is connected to INH then it will be disabled from the LIN bus.

A WAKE-UP-event or EN=high sets INH=high.
