2.1.6 Inhibit (INH) High Voltage Output

The inhibit output terminal is used to control system power management devices allowing for extremely low system current consumption in sleep mode. Use this terminal to enable and disable local power supplies. The pin has two states: driven high, and high impedance (High Z).

When high (on) the terminal will show VSUP minus a diode voltage drop. In the high impedance state the output will be left floating. The INH pin will be high for normal, silent, go to sleep, and standby modes. It will be low when in sleep mode. INH is available via JMP2 position 10 and TP8.
