13.4 Output Enable (OE) Input

The Output Enable Input pin is used to enable/disable the output driver and the on-board functions. When OE is high, all device functions are enabled. When OE is low, the device operates in Standby or Sleep mode. When Standby mode is active, the V_BOOT output supply and charge pump are disabled. The high-side and low-side gate drive outputs are all set to a Low state within 100 ns of OE going low. The device transitions to Standby or Sleep mode, 1 ms after OE goes low.

The OE pin may be used to clear any hardware Faults. When a Fault occurs, the OE input may be used to clear the Fault by setting the pin low and then high again. The Fault is cleared by the rising edge of the OE signal if the hardware Fault is no longer active.

The OE pin is used to enable Sleep mode when the SLEEP bit in the CFG0 Configuration register is set to a ‘1’. OE must be low for a minimum of ms before the transition to Standby or Sleep mode will occur. This allows time for OE to be toggled, to clear any Faults, without going into Sleep mode.

The OE pin has an internal 51 kΩ pull-down to ground.
